- Abstract
Objective: Preoperative atrial fibrillation (AF) increases risk of stroke, heart failure, and all-cause mortality after cardiac surgery. Despite encouraging results and guideline recommendations, surgical ablation (SA) for AF concomitant with other heart surgery remains low. In the current study we aimed to address the long-term mortality after SA concomitant with cardiac surgery., Methods: This report pertains to the HEart surgery In atrial fibrillation and Supraventricular Tachycardia (HEIST) registry. We identified 20,765 adult patients (62% male) with preoperative AF who underwent conventional sternotomy heart surgery between 2010 and 2021 in 8 tertiary centers in Poland, Netherlands, and Italy. We used Cox proportional hazards models for computations and propensity score matching to minimize differences in baseline characteristics., Results: Of included patients, 2755 (13.4%) underwent SA for AF. The highest rates of SA were observed for mitral interventions (mitral valve repair or replacement and tricuspid intervention, 25.2%), lowest for isolated coronary artery bypass grafting (6.2%). Patients in the SA group were younger (mean age 64.5 ± 9.0 years vs 68.7 ± 16.0 years; P < .001) and lower risk (mean European System for Cardiac Operative Risk Evaluation [EuroSCORE] II, 4.1 vs 5.7; P < .001). During the 11-year study period, there was a mortality reduction associated with SA (hazard ratio, 0.57; 95% CI, 0.52-0.62; P < .001). After propensity matching, 2750 pairs with similar baseline characteristics were identified. SA was associated with 16% mortality decline (hazard ratio, 0.84; 95% CI, 0.75-0.94; P = .003)., Conclusions: In this multicenter, retrospective, propensity matched study, SA concomitant with other cardiac surgery was associated with improved long-term survival regardless of baseline surgical risk., (Copyright © 2022 The American Association for Thoracic Surgery.

- Abstract
One of the target of perioperative tratment in surgery is decreasing intraoperative bleeding, which increases the number of perioperative procedures, mortality and treatment costs, and also causes the risk of transfusion of blood and its components. Trying to minimize the blood loss(mainly during the operation) as well as the need to transfuse blood and its components (broadly understood perioperative period) should be standard treatment for a patient undergoing a procedure. In the case of this method, the following steps should be taken: 1) in the preoperative period: identyfication of risk groups as quickly as possible, detecting and treating anemia, applying prehabilitation, modyfying anticoagulant treatment, considering donating one's own blood in some patients and in selected cases erythropoietin preparations; 2) in the perioperative period: aim for normothermia, normovolemia and normoglycemia, use of surgical methods that reduce bleeding, such as minimally invasive surgery, high-energy coagulation, local hemostatics, prevention of surgical site infection, proper transfusion of blood and its components if it occurs; 3) in the postoperative period: monitor the condition of patients, primarily for the detection of bleeding, rapid reoperation if required, suplementation (oral administration preferred) nutrition with microelements (iron) and vitamins, updating its general condition. All these activities, comprehensively and in surgical cooperation with the anesthesiologist, should reduce the blood loss and transfusion of blood and its components.

- Abstract
Objective: The objective of this study was to report midterm clinical outcomes with a self-expandable sutureless aortic valve., Methods: Between 2010 and 2013, 658 patients at 25 European institutions received the Perceval sutureless valve (LivaNova Plc, London, United Kingdom). Mean follow-up was 3.8 years; late cumulative follow-up was 2325.2 patient-years., Results: The mean age of the population was 78.3 ± 5.6 years and 40.0% (n = 263) were 80 years of age or older; mean Society of Thoracic Surgeons-Predicted Risk of Mortality score was 7.2 ± 7.4. Concomitant procedures were performed in 31.5% (n = 207) of patients. Overall duration of cardiopulmonary bypass time was 64.8 ± 25.2 minutes and aortic cross-clamping time was 40.7 ± 18.1 minutes. Thirty-day all-cause mortality was 3.7% (23 patients), with an observed:expected ratio of 0.51. Overall survival was 91.6% at 1 year, 88.5% at 2 years, and 72.7% at 5 years. Peak and mean gradients remained stable during follow-up, and were 17.8 ± 11.3 mm Hg and 9.0 ± 6.3 mm Hg, respectively, at 5 years. Preoperatively, 33.4% of those who received the Perceval valve (n = 210) were in New York Heart Association functional class I or II versus 93.1% (n = 242) at 5 years., Conclusions: This series, representing, to our knowledge, the longest follow-up with sutureless technology in a prospective, multicenter study, shows that aortic replacement using sutureless valves is associated with low mortality and morbidity and good hemodynamic performance., (Copyright © 2021 The American Association for Thoracic Surgery.

- Abstract
Cardiac stereotactic body radiotherapy is an emerging treatment method for recurrent ventricular tachycardia refractory to invasive treatment methods. The single-fraction delivery of 25 Gy was assumed to produce fibrosis, similar to a post-radiofrequency ablation scar. However, the dynamics of clinical response and recent preclinical findings suggest a possible different mechanism. The data on histopathological presentation of post-radiotherapy hearts is scarce, and the authors provide significantly different conclusions. In this article, we present unique data on histopathological examination of a heart explanted from a patient who had a persistent anti-arrhythmic response that lasted almost a year, until a heart failure exacerbation caused a necessity of a heart transplant. Despite a complete treatment response, there was no homogenous transmural fibrosis in the irradiated region, and the overall presentation of the heart was similar to other transplanted hearts of patients with advanced heart failure. In conclusion, our findings support the theorem of functional changes as a source of the anti-arrhythmic mechanism of radiotherapy and show that durable treatment response can be achieved in absence of transmural fibrosis of the irradiated myocardium., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Miszczyk, Sajdok, Nożyński, Cybulska, Bednarek, Jadczyk, Latusek, Kurzelowski, Dolla, Wojakowski, Dyla, Zembala, Drzewiecka, Kaminiów, Kozub, Chmielik, Grza̧dziel, Bekman, Gołba and Blamek.)

- Abstract
Objectives: Although endorsed by international guidelines, complete revascularization (CR) with Coronary Artery Bypass Grafting (CABG) remains underused. In higher-risk patients such as those with pre-operative atrial fibrillation (AF), the effects of CR are not well studied., Methods: We analyzed patients' data from the HEIST (HEart surgery In AF and Supraventricular Tachycardia) registry. Between 2012 and 2020 we identified 4770 patients with pre-operative AF and multivessel coronary artery disease who underwent isolated CABG. We divided the cohort according to the completeness of the revascularization and used propensity score matching (PSM) to minimize differences between baseline characteristics. The primary endpoint was all-cause mortality., Results: Median follow-up was 4.7 years [interquartile range (IQR) 2.3-6.9]. PSM resulted in 1,009 pairs of complete and incomplete revascularization. Number of distal anastomoses varied, accounting for 3.0 + -0.6 vs. 1.7 + -0.6, respectively. Although early (< 24 h) and 30-day post-operative mortalities were not statistically different between non-CR and CR patients [Odds Ratio (OR) and 95% Confidence Intervals (CIs): 1.34 (0.46-3.86); P = 0.593, Hazard Ratio (HR) and 95% CIs: 0.88 (0.59-1.32); P = 0.542, respectively] the long term mortality was nearly 20% lower in the CR cohort [HR (95% CIs) 0.83 (0.71-0.96); P = 0.011]. This benefit was sustained throughout subgroup analyses, yet most accentuated in low-risk patients (younger i.e., < 70 year old, with a EuroSCORE II < 2%, non-diabetic) and when off-pump CABG was performed., Conclusion: Complete revascularization in patients with pre-operative AF is safe and associated with improved survival. Particular survival benefit with CR was observed in low-risk patients undergoing off-pump CABG., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Pasierski, Staromłyński, Finke, Litwinowicz, Filip, Kowalówka, Wańha, Kołodziejczak, Piekuś-Słomka, Łoś, Stefaniak, Wojakowski, Jemielity, Rogowski, Deja, Jagielak, Bartus, Mariani, Li, Matteucci, Ronco, Jiritano, Fina, Martucci, Meani, Raffa, Słomka, Malvidni, Lorusso, Zembala, Suwalski and Kowalewski.)

- Abstract
Objectives: In the third report of the European Registry for Patients with Mechanical Circulatory Support of the European Association for Cardio-Thoracic Surgery, outcomes of patients receiving mechanical circulatory support are reviewed in relation to implant era., Methods: Procedures in adult patients (January 2011-June 2020) were included. Patients from centres with <60% follow-ups completed were excluded. Outcomes were stratified into 3 eras (2011-2013, 2014-2017 and 2018-2020). Adverse event rates (AERs) were calculated and stratified into early phase (<3 months) and late phase (>3 months). Risk factors for death were explored using univariable Cox regression with a stepwise time-varying hazard ratio (<3 vs >3 months)., Results: In total, 4834 procedures in 4486 individual patients (72 hospitals) were included, with a median follow-up of 1.1 (interquartile range: 0.3-2.6) years. The annual number of implants (range: 346-600) did not significantly change (P = 0.41). Both Interagency Registry for Mechanically Assisted Circulatory Support class (classes 4-7: 23, 25 and 33%; P < 0.001) and in-hospital deaths (18.5, 17.2 and 11.2; P < 0.001) decreased significantly between eras. Overall, mortality, transplants and the probability of weaning were 55, 25 and 2% at 5 years after the implant, respectively. Major infections were mainly noted early after the implant occurred (AER<3 months: 1.44 vs AER>3 months: 0.45). Bilirubin and creatinine levels were significant risk factors in the early phase but not in the late phase after the implant., Conclusions: In its 10 years of existence, EUROMACS has become a point of reference enabling benchmarking and outcome monitoring. Patient characteristics and outcomes changed between implant eras. In addition, both occurrence of outcomes and risk factor weights are time dependent., (© The Author(s) 2022.

- Abstract
Background: Continuous-flow left ventricular assist devices (LVADs) have been extensively used in a strategy of bridge to orthotopic heart transplant and destination therapy. The usage of LVAD, however, is not free from limitations such as device-related adverse events, including pump thrombosis (PT). We aimed to develop an algorithm of early PT detection based on the maintenance parameters monitored by the implanted device., Methods: We analyzed log files of 101 patients implanted with HeartWare pump (HVAD) with 18 PT events among them. For signal processing, we used the open-high-low-close format transformation and typical price (TP) technical analysis indicator. Model parameters were tuned with 5-fold cross-validation, and the final performance was measured on a separate group of patients., Results: Our algorithm achieved 100% sensitivity and 100% specificity of indications. In the final evaluation, alarms preceded the clinical acknowledgement of events by 2 days and 20 h on average. In the worst-case scenario, an alarm was raised 1 day and 8 h prior to the event., Conclusions: The proposed algorithm could be installed to work directly with the device controller and provide clinicians with automatic readings analysis, raising an alarm when there is a high probability of thromboembolism. Early event detection could enable better thrombosis management and improve prognosis in patients implanted with HVAD., (© 2022 International Center for Artificial Organs and Transplantation and Wiley Periodicals LLC.)

- Abstract
Introduction: With the development of less invasive techniques ministernotomy has become an increasingly popular choice for minimally invasive aortic valve replacement (MIAVR). However, a large discrepancy in the published results, often derived from the center's own experience, intensifies the need for further re-evaluation in order to better define the real impact of the ministernotomy approach on postoperative clinical condition in short- and long-term observation., Aim: To assess the safety and efficacy of MIAVR in comparison to a reference full sternotomy AVR (FSAVR)., Material and Methods: Between January 2004 and January 2018, 2386 patients underwent isolated surgical aortic valve replacement (AVR) at our institution. 620 patients were treated minimally invasively (MIAVR) and 1766 patients received FSAVR. Forced propensity score 1 : 1 matching and conditional regressive methods were introduced, ensuring valid comparison and correct estimation. Ultimately, 557 well allocated pairs of treated and control patients were included., Results: In-hospital mortality was low and comparable (1.26% for MIAVR, 1.62% for FSAVR). No significant differences in terms of serious adverse events were found, although in patients undergoing MIAVR there tended to be lower incidence of neurological complications (OR = 0.72; p = 0.09) and low output syndrome (OR = 0.66; p = 0.13). In addition to a much faster extubation and discharge from the ICU as well as improved blood management, MIAVR significantly reduced the risk of wound complications (OR = 0.31; p < 0.0010)., Conclusions: MIAVR is a safe, effective and reproducible procedure providing at least as good results as FSAVR. Nevertheless, it should be especially recommended to obese, diabetic patients with pulmonary and mobility disorders in order to improve their early recovery., Competing Interests: The authors report no conflict of interest., (Copyright: © 2022 Polish Society of Cardiothoracic Surgeons (Polskie Towarzystwo KardioTorakochirurgów) and the editors of the Polish Journal of Cardio-Thoracic Surgery (Kardiochirurgia i Torakochirurgia Polska).)

- Abstract
Background: Data concerning the comparison between transcatheter aortic valve implantation and surgical aortic valve replacement in a real-world setting are scarce and in Central and Eastern Europe no such data exist. In this study, we aimed at analyzing retrospectively the characteristics and outcome of patients with aortic stenosis treated either with surgical aortic valve replacement or transcatheter aortic valve implantation between 2006 and 2016 in the Silesian Province, Poland in a representative real-world cohort., Methods: In the Silesian Cardiovascular Database we retrospectively identified 5186 patients who received either transcatheter aortic valve implantation or surgical aortic valve replacement in 1 of 3 tertiary cardiovascular centers. Baseline characteristics, including relevant clinical history, and outcomes were compared before and after propensity-score matching of both groups, with 348 pairs of patients constituting the propensity-matched study cohort. The primary end-point was 24-month all-cause mortality., Results: Preoperative characteristics of propensity-matched groups were similar. There was no difference between transcatheter aortic valve implantation and surgical aortic valve replacement groups with respect to the death rate at 2 years (19.9% vs. 15.6%; P =.479). In the transcatheter aortic valve implantation group, cardiac resynchronization therapy devices were more frequently implanted after the procedure (3.7% vs. 0.0, P <.001). The groups had similar rates of myocardial infarction, stroke, and re-hospitalization. Hospital stay in the matched groups was shorter after transcatheter aortic valve implantation: 14.1 versus 15.7 days (P <.001)., Conclusions: At 24 months, transcatheter aortic valve implantation patients had similar outcomes as surgical aortic valve replacement except for a higher rate of cardiac resynchronization therapy device implantation and shorter hospital stay.

- Abstract
Introduction: Transcatheter aortic valve‑in ‑valve implantation (ViV‑TAVI) has emerged as an alternative to redo surgery in patients with failed surgical aortic bioprosthesis., Objectives: We evaluated the safety and efficacy of ViV‑TAVI in Polish patients after surgical aortic valve replacement., Patients and Methods: This was a nationwide multicenter registry of ViV‑TAVI procedures. Data were collected using an online form, and the clinical follow ‑up lasted 1 year., Results: From 2008 to 2020, 130 ViV‑TAVI procedures were performed (1.9% of all transcatheter aortic valve implantation [TAVI] cases). A considerable increase in ViV‑TAVI procedures since 2018 has been observed (n = 59, 45% of ViV‑TAVI cases). Hancock II, Freestyle, and homograft were the most frequently treated bioprostheses. The self ‑expanding supra ‑annular Corevalve / Evolut valve was used in 76% of cases. In 21% of cases, the mean postprocedural pressure gradient (PG) exceeded 20 mm Hg. All‑cause mortal‑ity at 1 year was 10.8%. Aortic valve stenosis was associated with a higher mean PG than aortic valve regurgitation or mixed disease (P = 0.004). Supra ‑annular transcatheter aortic valves were associated with lower mean PGs than intra ‑annular valves (P = 0.004). Second ‑generation devices were associated with shorter procedure time (120 min vs 135 min, P = 0.04), less frequent need for additional TAVI (2% vs 10%, P = 0.04), and lower 1‑year cardiovascular mortality (95% vs 82.8%, P = 0.03) than first‑generation valves., Conclusions: Transcatheter treatment of failed bioprostheses is increasingly common, with the best hemodynamic effect shown for supra ‑annular valves. The introduction of second‑generation valves has improved procedural and clinical outcomes.

- Abstract
Background: This study aimed to assess long-term results after surgical AVR (sAVR) depending on the used surgical technique (ministernotomy vs. full sternotomy) and to determine which patient- and treatment-related attributes were most associated with shorter time to the main endpoint., Methods: Out of 2147 patients, who underwent sAVR from January 2006 to December 2017, 615 patients were treated minimally invasively (MIAVR) and 1532 patients received conventional full sternotomy aortic valve replacement (FSAVR). Multiple Cox regressive models corresponding to the four major endpoints were developed. Long-term survival and a time to re-hospitalization for acute coronary syndrome, stroke, and heart failure (HF) were analyzed independently. Kaplan-Meier actuarial analysis was performed for univariate comparison., Results: The median follow-up time was 71.9 months. No significant difference in terms of long-term survival was found between MIAVR and FSAVR (hazard ratio [HR], 0.99; P = 0.91). Novel advantages of MIAVR in preventing re-hospitalization for late cerebrovascular events and the progression of HF were observed (HR, 0.53; P = 0.03; HR, 0.64, P = 0.005; respectively). Importantly, for the late mortality risk, early in-hospital complications dominated. However, the baseline atrial fibrillation (AF), diabetes, pulmonary disease, and impaired mobility showed the strongest patient-specific prediction for the other three long-run models., Conclusions: MIAVR through ministernotomy provides at least as good long-term survival as FSAVR. Nevertheless, it should be recommended for diabetic, poor-mobility patients with pre-existing AF to reduce their high cerebrovascular risk and to limit the progression of HF. MIAVR also needs to be considered in patients with chronic lung diseases to improve their extremely poor survival prognosis.

- Abstract
Observational studies suggest improved outcomes with multiple (MAG) as compared to single arterial grafting (SAG) in patients with multivessel coronary artery disease and undergoing coronary artery bypass grafting (CABG). Even though around 6% of CABG patients have preoperative atrial fibrillation, previous studies did not address MAG versus SAG comparison in this setting. Data from KROK (Polish National Registry of Cardiac Surgery Procedures) were retrospectively collected. 5738 patients with multivessel coronary artery disease and AF (77.9% men, mean age 69.0 ± 8.0) undergoing isolated CABG surgery between 2006 and 2019 in 37 reference centers across Poland were analyzed. Propensity score matching was performed. Primary endpoint was mid-term survival. Median follow-up was 5 years ([IQR 1.9-7.6], max.13). One-to-three Propensity score matching included 2364 patients divided into MAG (591) and SAG (1773) subsets. Subjects were no different in terms of baseline risk and surgical characteristics. Number of distal anastomoses was 2.82 ± 0.83 versus 2.80 ± 0.75 (P = 0.516) for MAG and SAG, respectively. In-hospital outcomes and mortality risk at 1-year (hazard ratio, 95% confidence intervals: 1.13 [0.81-1.58]; P = 0.469) was unchanged with MAG. Multiple arterial grafting was associated with 20% improved mid-term survival: HR 0.80; (95% confidence intervals: 0.65-0.97); P = 0.026. Benefit was sustained in subgroup analyses, yet most appraised in low risk patients (<70-year-old; EuroSCORE <2; no diabetes) and when complete revascularization was achieved. Multiple as compared to single arterial grafting in atrial fibrillation patients undergoing CABG is safe and associated with improved mid-term survival. A particular survival benefit was observed in lower risk patients., (Copyright © 2020 Elsevier Inc. All rights reserved.)

- Abstract
Introduction: Cardiac allograft vasculopathy remains one of the most important factors leading to chronic cardiac allograft rejection. When revascularization is needed percutaneous coronary interventions are the method of choice., Aim: To compare the short- and long-term outcomes of cardiac allograft vasculopathy patients treated with everolimus- (EES) or sirolimus-eluting stents (SES)., Material and Methods: Between December 2012 and December 2020, 319 patients after heart transplantation undergoing coronary angiography at our institution were analysed. Subsequently 39 patients underwent de novo angioplasty with second-generation EES. The primary study endpoint was angiographic restenosis as evaluated by quantitative coronary angiography. Secondary outcomes included binary restenosis, target lesion revascularization and cardiac death during the follow-up period (6 months)., Results: Twenty-four patients were treated with EES and 15 treated with SES. No significant differences were observed regarding the rate of risk factors of cardiovascular diseases and comorbidities. The patients treated with EES were younger (55.8 ±11.8 vs. 60.1 ±12.2) and less frequently male (79% vs. 93%). The majority of patients were diagnosed with single vessel disease with LAD involvement (62% and 86% in the EES group, and 47% and 56% in the SES group). In 6 months follow-up, late lumen loss was comparable in both groups, 0.19 ±0.15 vs. 0.14 ±0.15, and binary restenosis was 4% and 0% for EES and SES groups, respectively., Conclusions: Second generation drug-eluting stents eluting rapamycin analogues are associated with high direct efficacy of procedures and low incidence of restenosis in a 6-month follow-up., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

- Abstract
Left ventricular assist device (LVAD) is well established as an alternative treatment for end-stage heart failure (HF) patients. The aim of the study was to determine the prognostic value of oxidative stress markers and the modified Model for End-Stage Liver Disease (modMELD) in patients receiving bridged therapy with continuous-flow LVAD. We prospectively analyzed 36 end-stage HF patients who received LVAD therapy between 2015 and 2018. The total antioxidant capacity (TAC) and total oxidant status (TOS) were measured by the methods described by Erel. The oxidative stress index (OSI) was defined as the ratio of the TOS to TAC levels. The modMELD scores were calculated based on the serum bilirubin, creatinine, and albumin levels. The patients' median age was 58 (50-63.0) years. During the 1.5-years follow-up, a major adverse cardiac event-MACE (death, stroke, or pump thrombosis) was observed in 17 patients (47.2%). The area under the receiver operating characteristics curves (AUCs) indicated a good prognostic power of TAC (AUC 0.7183 (0.5417-0.8948)), TOS (AUC 0.9149 (0.8205-0.9298)), OSI (AUC 0.9628 (0.9030-0.9821)), and modMELD (AUC 0.87 (0.7494-0.9905)) to predict a MACE. Oxidative stress markers serum concentrations, as well as the modMELD score, allow the identification of patients with a risk of MACE.

- Abstract
Heart transplantation is performed in patients with end-stage heart failure. The number of suitable donors for patients on the urgent heart transplantation waiting list is still low, and effort has been made to increase the number of suitable donors, including extended-criteria donors. We present a case report of heart retransplantation because of graft failure from an hepatitis B core antibody (anti-HBcore-positive, HBcAb [+]) and HBs antigen-negative (HBsAg [-]) donor to a seronegative recipient. We show that the procedure, with the use of antiviral prophylaxis, is a safe option for the recipient. Based on anatomopathologic and histopathologic examination of the explanted graft, we also suggest that acute cellular rejection in the transplanted heart may exist despite negative findings in right-sided endomyocardial biopsy., (Copyright © 2021 Elsevier Inc.

- Abstract
Background: The prognosis of men and women with chronic coronary syndromes (CCS) remains ambiguous., Aims: This study aimed to compare the clinical characteristics and 12‑month prognosis of women and men with CCS included in the prospective single‑center registry., Methods: The study was based on the Prospective Registry of Stable Angina Management and Treatment (PRESAGE) including 11 021 patients with CCS hospitalized between 2006 and 2016 and subjected to coronary angiography. The composite endpoint included all‑cause death, nonfatal myocardial infarction, acute coronary syndrome with revascularization, unstable coronary artery disease, or stroke., Results: Women were older than men (mean [SD] age, 66.6 [9] vs 63.5 [9.6] years; P <0.001). Arterial hypertension (85.8% vs 79%; P <0.001) and type 2 diabetes (38.2% vs 33.7%; P <0.001) were more often diagnosed in women compared with men. Multivessel disease or left main disease were more frequent in men. Percutaneous coronary intervention and coronary artery bypass grafting were more often performed in men than in women (47.1% vs 36%, P <0.001 and 10.6% vs 6.1%, P <0.001, respectively). At 12‑month follow‑up, the composite endpoint was more frequently reached in men (7.4% vs 10.2%; P <0.001), including death (3.3% vs 4.5%; P = 0.002). In multivariable analysis, sex was not an independent predictor of the composite endpoint (hazard ratio, 1.08; 95% CI, 0.89-1.31, P = 0.45)., Conclusions: Women and men with CCS differ in terms of the incidence of risk factors and revascularization treatments received. In men, a higher frequency of death and the composite endpoint was noted at 12‑month follow‑up. However, sex was not an independent predictor of patient outcomes at 12 months.

- Abstract
Background: The aim of the study was a comparison of culprit-lesion-only (CL-PCI) with the multivessel percutaneous coronary intervention (MV-PCI) in terms of 30-day and 12-month mortality in a national registry., Methods: Patients from the PL-ACS registry with MI and CS were analyzed. Patients meeting the criteria of the CULPRIT-SHOCK trial were divided into two groups: CL-PCI and MV-PCI groups., Results: Of the 3265 patients in the PL-ACS registry with MI complicated by CS, the criteria of the CULPRIT-SHOCK trial were met by 2084 patients (63.8%). The CL-PCI was performed in 883 patients, and MV-PCI was performed in 1045 patients. After the propensity score matching analysis, 617 well-matched pairs were obtained. In a 30-day follow-up, death from any cause occurred in 49.3% in the CL-PCI group and 57.0% in the MV-PCI group (RR 0.86, 95% CI 0.58-0.92, p = 0.0081). After 12 months, the rate of mortality was 62.5% in the CL-PCI group and 68.0% in the MV-PCI group (RR 0.92, 95% CI 0.84-1.01, p = 0.066)., Conclusions: The results confirm the validity of CULPRIT-SHOCK findings in a national registry and current guideline-recommended strategy of revascularization limited to the infarct-related artery.

- Abstract
Introduction: Indications for transcatheter aortic valve implantation (TAVI) are constantly expanding, including younger patients. Bicuspid aortic valves (BAV) often occur in this group. In order to achieve optimal treatment results in younger patients, it is necessary to develop an effective method for selecting the size of implanted valves., Aim: To compare the results of TAVI with use of a self-expanding prosthesis in patients with a BAV and a tricuspid aortic valve (TAV) with valve selection based on annular sizing., Material and Methods: The diagnosis of BAV and TAV and measurements (annular sizing) were based on multi-slice computed tomography scans. Eighty-three patients received a self-expanding CoreValve or Evolut R prosthesis. In group I (BAV) there were 21 (25.3%) patients and in group II (TAV) there were 62 (74.7%) patients., Results: The groups did not differ in terms of baseline clinical characteristics. Device success was achieved in 16 (76.2%) and 55 (88.7%) ( p = NS) in group I and II respectively. Composite endpoints: early safety occurred in 5 (23.8%) and 11 (17.7%) patients ( p =NS) in group I and II respectively; clinical efficacy occurred in 10 (47.6%) and 28 (45.2%) patients ( p = NS) in group I and II respectively. 30-day mortality was 4.8% vs 9.7%, 1-year mortality was 28.6% vs 17.7% ( p = NS) in group I and II respectively., Conclusions: TAVI in patients with severe aortic stenosis and BAV is as effective as in patients with TAV using self-expanding prostheses if the valve selection is based on annular sizing., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

- Abstract
BACKGROUND Lung transplant recipients may suffer from airway stenosis (AS). The aim of this study was to assess whether pulmonary function (as measured by spirometry and a 6-minute walk test [6MWT]) in patients with AS treated consistently with bronchoscopic interventions (BIs) was comparable to that in their AS-free counterparts at the 1-year follow-up visit. MATERIAL AND METHODS Fifty patients who underwent primary double-lung transplantation between January 2015 and March 2019 at a single center (23 who received BIs and 27 who did not) were enrolled in this retrospective study. Graft function was assessed with spirometry, based on forced expiratory volume (FEV₁) and forced vital capacity (FVC), both measured in liters (L) and percentages (%), and the Tiffeneau-Pinelli index (FEV₁/FVC), and a 6MWT and parameters such as oxygen saturation measured before and after the test. RESULTS Patients in need of BIs had significantly lower FEV₁% compared with individuals who did not receive BIs during their first post-transplant year. Airway obstruction was present in 22% of patients who did not receive BIs and 65.23% of those who did receive the interventions. There were statistically significant, strong, negative correlations pertaining to the number of balloon BIs and 1-year FEV₁% (rs=0.67) as well as the number of balloon BIs and 1-year FEV₁/FVC (rs=0.72). A statistically significant, strong, negative correlation (rs=0.75) was found between the number of balloon bronchoplasty treatments and oxygen saturation after the 6WMT. CONCLUSIONS Despite receiving BIs, patients who experience bronchial stenosis may not obtain the expected ventilatory improvement at their 1-year follow-up visit. Their AS may recur or persist despite use of various procedures. Further study in that regard is required.

- Abstract
Infant respiratory distress syndrome (IRDS) develops among premature infants due to structural immaturity of the lungs and insufficient production of pulmonary surfactant. Nowadays, treatment takes place under conditions of intensive care and includes oxygen therapy, mechanical ventilation, exogenous supplementation of pulmonary surfactant and antenatal corticosteroid therapy. The treatment of IRDS, especially mechanical ventilation, may lead to complications which can contribute to developing a severe dysfunction of the respiratory system. Unavailability of pharmacological treatment of IRDS and development of pulmonary barotrauma due to mechanical ventilation in our patient led to the forming of severe pulmonary interstitial emphysema. In this case report, lung transplantation was performed as an only successful therapeutic option.

- Abstract
Mechanical circulatory support (MCS) methods are used in patients with both acute and chronic heart failure, who have exhausted other options for pharmacological or surgical treatments. The purpose of their use is to support, partially or completely, the failed ventricles and ensure adequate organ perfusion, which allows patients to restore full cardiovascular capacity, prolonging their life and effectively improving its quality. The three most popular devices include an intra-aortic balloon pump (IABP), percutaneous assist devices (including Impella, TandemHeart), and venoarterial extracorporeal membrane oxygenation (VA-ECMO). A multidisciplinary approach with the special participation of the Heart Team is required to determine the proper MCS strategy, the choice of the supporting method, and the time of its use. The studies published so far do not allow us to determine which MCS method is the safest and the most effective. Thus, the site experience and accessibility of the method seem to matter most today. MCS finds particular application in patients with acute coronary syndromes complicated by refractory cardiogenic shock, as well as in patients with acute heart failure of the high potential for reversibility. It can also serve as a backup for percutaneous coronary interventions of high risk (complex and high-risk indicated percutaneous coronary intervention [PCI], complex and high-risk indicated PCI [CHIP]). The use of appropriate supportive drugs, precise hemodynamic and echocardiographic monitoring, as well as optimal non-invasive or mechanical ventilation, are extremely important in the management of a patient with MCS. The most serious complications of MCS include bleeding, thromboembolic events, as well as infections, and hemolysis.

- Abstract
A 44-year-old male with no history of underlying diseases was referred to academic hospital due to ARDS with confirmed SARSCoV-2 infection after 7 days of mechanical ventilation. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated as no improvement was noted in prone position. Mechanical ventilation was continued with TV of 3-4 mL/kg. A gradual decline of static lung compliance was observed from baseline 35 mL/cm H20 to 8 mL/cm H2O. The chest CT scan revealed extensive ground-glass areas with a significant amount of traction bronchiectasis after 3 weeks since admission. When the patient was negative for SARS-CoV-2 during the 4th week of ECMO, the decision to perform an emergency lung transplantation (LTx) was made based on the ongoing degradation of lung function and irreversible damage to lung structure. The patient was transferred to the transplant center where he was extubated, awaiting the transplant on passive oxygen therapy and ECMO. Double lung transplantation was performed on the day 30th of ECMO. Currently, the patient is self-reliant. He does not need oxygen therapy and continues physiotherapy. ECMO may be life-saving in severe cases of COVID-19 ARDS but some of these patients may require LTx, especially when weaning proves impossible. VV ECMO as a bridging method is more difficult but ultimately more beneficial due to insufficient number of donors, and consequently long waiting time in Poland.

- Abstract
Introduction: There is a paucity of real‑world registries concerning patients with chronic coronary syndromes (CCS)., Objectives: We aimed to assess the long‑term outcomes of patients with CCS and after coronary angiography performed in accordance with the treatment strategy., Patients and Methods: The analysis involved 11 021 patients treated in a single center between 2006 and 2016 who were enrolled into the ongoing PRESAGE registry. Based on the results of coronary angiography and the treatment strategy adopted, patients were classified into 4 groups: with nonsignificant lesions (n = 3637), undergoing percutaneous coronary intervention (n = 4678), undergoing coronary artery bypass grafting (CABG; n = 997), and receiving conservative treatment (notwithstanding significant lesions on an angiogram; n = 1709). All‑cause death, assessed in every study group at 1-, 3-, and 5‑year follow‑up, was regarded as the primary outcome measure., Results: The mean (SD) age of the study patients was 64.6 (9.5) years, and women constituted 35% of the cohort. Patients treated conservatively were the oldest (mean [SD] age, 64.9 [9.3] years) in the group and showed the highest prevalence of previous myocardial infarction (50.5%), CABG (31.8%), diabetes (40.3%), chronic total occlusion (65.5%), and left ventricular ejection fraction below 35% (24.4%). Death from any cause in patients with nonsignificant lesions, undergoing percutaneous coronary intervention, undergoing CABG, and receiving conservative treatment occurred 5 years following the index hospitalization in 11.2%, 16.2%, 9.7%, and 21% of those patients, respectively., Conclusions: The PRESAGE registry provides valuable information about the clinical characteristics and long‑term outcomes of patients with CCS. The population of CCS patients is heterogeneous, and long‑term prognosis is also varied. The poorest characteristics and outcomes were reported in patients with significant lesions and ineligible for revascularization procedures.

- Abstract
Introduction: Despite the establishment of multiple factors influencing short- and mid-term outcomes in patients treated with transcatheter aortic valve implantation (TAVI), the real-world data on the association between gender and outcomes after TAVI remain conflicting., Aim: To evaluate the association of female gender with the clinical and periprocedural characteristics along with in-hospital, short- and medium-term outcomes of patients treated with TAVI in comparison with male patients., Material and Methods: Data from the prospective, single-centre registry of consecutive patients with severe AS referred for TAVI from 26 November 2008 to 31 December 2018 were analysed retrospectively. The study population comprised 275 patients who were divided by gender. The primary endpoint of the study was all-cause mortality at 1 year., Results: Women constituted 132 (48.0%) of the overall population. Women were significantly older, but had a significantly higher left ventricular ejection fraction (LVEF) and had less frequently undergone coronary artery bypass grafting (CABG) before TAVI. The implantation success rate was comparable between genders, but women less frequently required implantation of a pacemaker after TAVI, although they more frequently required blood transfusion due to severe bleeding. The primary endpoint occurred in 13.6% of women and 7.7% of men ( p = 0.12)., Conclusions: Despite advanced age and prevalence of cardiovascular risk factors, the overall short- and medium-term mortality in patients treated with TAVI in our analysis of the real-world population remains relatively low. Although women seemed to have a slightly better clinical baseline profile, their in-hospital, 30-day, 6-month and 12-month outcomes did not differ significantly from the male patients., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Termedia Sp. z o. o.)

- Abstract
Background: An increasing number of patients with end‑stage heart failure implies a wider use of left ventricular assist devices (LVADs). Irreversible pulmonary hypertension (PH) is a predictor of unfavorable prognosis and a contraindication to orthotopic heart transplant (OHT)., Aims: The aim of this study was to evaluate the effect of continuous‑flow LVAD (CF‑LVAD) support on pulmonary pressure and pulmonary vascular resistance (PVR) as well as the impact of pre‑LVAD hemodynamic parameters on survival during LVAD support., Methods: Data collected from 106 patients who underwent CF‑LVAD implantation in the years 2009 to 2018 (men, 95.3%; mean [SD] age, 51.8 [12] years; mean [SD] INTERMACS profile, 2.9 [1.6]; mean [SD] LVAD support time, 661 [520] days; follow‑up until May 2019) were retrospectively analyzed., Results: Right heart catheterization was performed before LVAD implantation in 94 patients (88.7%), after implantation-in 31 (29.2%), and before and after implantation-in 28 (26.4%). We observed mean pulmonary artery pressure (mPAP) >25 mm Hg in 65 patients (61.3%) and PVR >2.5 Wood units in 33 patients (31.1%) before LVAD implantation. A significant improvement after CF‑LVAD implantation was noted in mPAP, pulmonary capillary wedge pressure, transpulmonary gradient, PVR, cardiac output (P <0.001 for all parameters), and cardiac index (P = 0.003). All patients with initially irreversible PH became eligible for OHT during LVAD support. Survival during LVAD support did not depend on initial mPAP and PVR., Conclusions: In patients with end‑stage heart failure, CF‑LVAD support leads to a significant reduction of pre‑ and postcapillary PH. Survival on CF‑LVAD support is independent of elevated mPAP and PVR before implantation, which suggests that LVADs decrease the risk associated with PH.

- Abstract
Background: Cystic fibrosis is a congenital, progressive disease affecting many organs. It frequently leads to severe respiratory failure, which can be treated by means of a double lung transplantation. Single lung transplantation is justified only in certain cases., Case Report: This is a case report describing a 20-year-old female patient who became the recipient of a single lung transplant as a result of cystic fibrosis. The transplant was performed during cardiothoracic surgery, which included an intervention in the right atrium. At the age of 14, the patient underwent left pneumonectomy. In addition, the patient had a percutaneous endoscopic gastrostomy placed and a vascular port implanted. During preoperative evaluation, she presented with clinical symptoms of chronic respiratory failure. The patient was approved for lung transplantation at the age of 16. After 2 years on the national lung transplant waiting list, in 2018, the patient underwent right lung transplantation and removal of numerous thrombi in the right atrium during 1 procedure. This surgery was accomplished with the use of extracorporeal circulation, which is an extracorporeal membrane oxygenator combined with cardiopulmonary bypass. The patient was discharged 3 weeks after the procedure in good general condition. Presently, her pulmonary function is excellent and she presents with normal respiratory capacity., Conclusions: Patients with cystic fibrosis often require double lung transplantation. Under normal circumstances, performing only a single lung transplantation would be considered medical malpractice. However, in certain cases, a single lung transplant is a life-saving procedure., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: In middle-aged patients undergoing aortic valve replacement (AVR), the selection of prosthesis type is a complex process. Current guidelines do not unequivocally indicate the type of prosthesis (bioprosthetic or mechanical) recommended for patients between 60-70 years of age. The aim of the study was to present the trends in AVR prosthesis selection in borderline patients over a 10-year period, based on real-life registry data., Methods: The study population comprised of 9,616 consecutive patients aged between 60-70 years, who underwent isolated AVR between 2006 and 2016 in all cardiac surgery departments in Poland. Data were extracted from the Polish National Registry of Cardiac Surgery., Results: Among 27,797 consecutive AVR procedures, patients aged 60-70 years represented 34.6% of the population operated on. From 2006 to 2016, bioprosthetic valves (BVs) were implanted in 53.9% cases, (and) mechanical valves (MVs) in 42.1%. The proportion of different valve types changed in time: from 77.5% of MVs vs. 22.5% of BVs in 2006 to 23.2% of MVs vs. 76.8% of BVs in 2016 (P<0.001). The most commonly implanted BV was the Hancock II (used in 36.4% of BV implantations), the most commonly used MV was the Saint Jude Mechanical prosthesis (implanted in 36.4% of MV implantation cases). A multivariable model identified smaller annulus [OR (95% CI) 0.89 (0.86-0.92), P<0.001], atrial fibrillation [OR (95% CI) 1.32 (1.05-1.67), P=0.017], male sex [OR (95% CI) 1.47 (1.24-1.74), P<0.001] and year of implantation [OR (95% CI) 0.75 (0.71-0.79), P<0.001] as predictors of MV implantation., Conclusions: Patients aged 60-70 years represent more than one-third of all AVR patients. Between 2006 and 2016, the proportion of implanted prostheses has changed dramatically. In 2016 BVs were implanted in nearly 75% of AVR cases, three times more often than in 2006., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/jtd-19-3586).

- Abstract
Oxidative stress is defined as an imbalance between the production of free radicals and their elimination by the antioxidant defense system. However, the role of oxidative stress in cardiac allograft vasculopathy (CAV) has not been fully understood. Therefore, this study is aimed at determining the role of oxidative-antioxidative balance disturbances in patients after HT. Furthermore, we sought to analyze factors associated with the presence of CAV, with particular emphasis placed on oxidative stress markers. The study analyzed data of 194 consecutive patients after HT who underwent routine visits in the Transplantation Clinic between 2015 and 2016. Total oxidant status (TOS) and total antioxidant capacity (TAC) were measured by the method described by Erel. The oxidative stress index (OSI) was defined as the ratio of the TOS to TAC levels. Patients' mean age was 55.4 ± 15.0 years, and 73.4% were men. The frequency of CAV was 50%. The area under the receiver operating characteristic curves indicated a good discriminatory power of TAC and TOS (0.8940 (0.8515-0.9365); 0.8620 (0.8126-0.9114), respectively) as well as excellent discriminatory power of OSI (0.9530 (0.9279-0.9781)) for CAV detection. Multivariate analysis of the Cox proportional hazard model confirmed that OSI (hazard ratio (HR) = 1.294 (1.204-1.391), p < 0.0001), age (HR = 1.023 (1.006-1.041), p = 0.0091), and high-sensitivity C-reactive protein (HR = 1.049 (1.016-1.083), p = 0.0151) were independently associated with CAV presence. In conclusion, TAC and TOS had a good discriminatory power and OSI had excellent strength for detecting CAV. The independent factors of CAV were higher OSI and CRP levels, as well as older recipient age., Competing Interests: The authors declare that they have no conflict of interest., (Copyright © 2020 Wioletta Szczurek et al.)

- Abstract
Background: According to the medical literature, both on-pump and off-pump coronary artery surgery is safe and effective in octogenarians., Objectives: The aim of our study was to examine the epidemiology, in-hospital outcomes and long-term follow-up results in octogenarians undergoing off-pump and on-pump coronary artery surgery utilizing nationwide registry data., Methods: All octogenarians (≥ 80 years) enrolled in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry), who underwent isolated coronary surgery between January 2006 and September 2017 were identified. Preoperative data, perioperative complications, hospital mortality and long-term mortality were analyzed. Unadjusted and propensity-matched comparisons were performed between octogenarians undergoing off-pump and on-pump coronary artery bypass surgery., Results: Octogenarians accounted for 4.1% of the total population undergoing coronary artery surgery in Poland during the analyzed period (n = 152,631) and this percentage is increasing. Among 6,006 analyzed patients, 2,744 (45.7%) were operated on-pump and 3,262 (54.3%) were operated off-pump. Propensity-matched analysis revealed that patients operated on-pump were more often reoperated due to postoperative bleeding and their in-hospital mortality was higher (6.6% vs 4.5%, p = 0.006 and 8.7% vs 5.8%, p = 0.001, respectively). Long-term all-cause mortality was lower among patients operated off-pump (p = 0.013)., Conclusion: On the basis of our findings we suggest that off pump technique should be considered as perfectly acceptable in octogenarians., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Introduction: Lung transplantation (LTx) is the only effective method of treatment to improve the health and quality of life (QoL) of patients with end-stage lung diseases. After LTx, medical examination accompanied by quality of life assessment should be performed on routine follow-up visits. The aim of the study was to assess the QoL of patients after LTx., Material and Methods: The study group consisted of 60 patients (29 women and 31 men); 20 patients received single lung transplantation (SLT), and 40 received double lung transplantation (DLT). To determine the patient's QoL, the General Health Questionnaire (GHQ), the World Health Organization Quality of Life Test-BREF (WHOQOL-BREF), and the Saint George Respiratory Questionnaire (SGRQ) were used. Spirometry and the 6-minute walk test were analyzed to examine efficiency of transplanted organs., Results: In SGRQ there are differences between patients with cystic fibrosis and interstitial lung disease in symptom domain (20.28% vs 39.26%, P = .025) and total score (19.38% vs 32.47%, P = .028). As reported in the GHQ, men had worse overall results than women in sten scale (5.22 points vs 4.69 points). Patients after SLT achieved similar scores in every questionnaire., Conclusion: Studies assessing QoL should be an important addition to lung function tests and an integral part of control during postoperative follow-up visits. This study is one of the important contributions to understanding of how essential QoL is after LTx. The authors of this study realize that their work does not cover the whole issue, and further studies in this area are warranted., (Copyright © 2020 The Authors. Published by Elsevier Inc.

Introduction: Secondary pulmonary hypertension (PH) is a serious complication of end-stage lung disease and is associated with unfavorable prognosis. The aim of the study was to evaluate the incidence and severity of secondary PH among patients qualified for lung transplantation (LTx)., Material and Methods: The study population consisted of 143 patients qualified for LTx between 2004 and 2019. Analyzed medical records included results collected during the qualification process (eg, echocardiography parameters, right heart catherization [RHC]). There were 37.8% (n = 54) of patients with chronic obstructive pulmonary disease (COPD), 58.7% (n = 84) of patients with interstitial lung diseases (ILDs), and 3.5% (n = 5) of patients with combined pulmonary fibrosis and emphysema (CPFE). The inclusion criteria were ILDs, COPD or CPFE diagnosis, and the presence of RHC data preformed during qualification for LTx. The exclusion criteria were lack of RHC results and diagnosis of idiopathic pulmonary artery hypertension, pulmonary artery hypertension associated with connective tissue disease, cystic fibrosis, or bronchiectasis., Results: PH was detected among 60.1% (n = 86) of patients qualified for LTx. The prevalence of PH was 39% (n = 18) vs 76.19% (n = 64) in the COPD vs ILDs groups, respectively. Both ILDs and COPD patients presented with similar mean artery pulmonary pressure (36.3 ± 9.61 vs 34.78 ± 11.47 mm Hg; not statistically significant). Severe PH was more frequent in the ILDs group than in the COPD group (60.94% vs 38.89%)., Conclusions: PH is commonly diagnosed in patients with chronic lung diseases qualified for LTx and more often observed among patients qualified because of ILDs. It is important to assess the pulmonary pressure because of frequent occurrence of PH among patients referred for LTx., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: The cold ischemia time (CIT) is a period of time between harvesting an organ for transplant and its reperfusion just after implantation. CIT may have an impact on frequency of complications after lung transplant that can be treated by means of bronchoscopic intervention. The aim of the study was to investigate the correlation between CIT and frequency of bronchoscopic intervention., Methods: The retrospective study consists of 91 patients: 22 single lung recipients (24%) and 69 double lung recipients (76%) who underwent lung transplant from March 2012 to June 2019. All statistical analyses were performed in SPSS 25.0 and R 3.5.3. The P levels less than .05 were deemed statistically significant., Results: The average CIT in single lung transplant was 5.91 hours, and in double lung transplant it was 8.61 hours. For the 4- to 8-hour CIT the percentages were 80.95% for single lung recipients and 46.38% for double lung recipients. For CIT longer than 8 hours, the following percentages were observed: 9.53% in single lung transplant and 53.62% in double lung transplant. Each subsequent hour of CIT exponentially increases the risk of intervention 1505 times (50.05%)., Conclusions: Prolonged CIT seems to be a risk factor for airway complication, especially in the double lung recipient group., (Copyright © 2020 The Authors.

- Abstract
Background: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide. Lung transplantation (LTx) is often the only therapeutic option for patients with end-stage COPD. The aim of the study was to establish whether patients with end-stage COPD benefited from lung transplantation and assess the pulmonary function by the 6-Minute Walk Test (6MWT) and forced expiratory volume in 1 second (FEV1)., Methods: A retrospective study was carried out in the group of 69 patients (40 recipients, 18 patients currently waiting, and 11 patients who died while waiting for a lung graft) diagnosed with end-stage COPD, referred to the Silesian Center for Heart Diseases' Lung Transplant Ward, and qualified to be treated by means of lung transplantation between 2006 and 2018. The beginning of the observation for all 69 patients was a qualification date., Results: Kaplan-Meier estimation determined that graft recipients noted 50% probability of survival at approximately 5.5 years, whereas patients from the other group had such parameters at about 1.4 years. The average results FEV1 obtained at qualification were 23.69% for single lung transplantation (SLT); and 22.06% for double lung transplantation (DLT). Average patient acquired 158.07m in the 6MWT. One year after procedure the average values of FEV1 were SLT, 55.83%; DLT, 79.54%; and 430.7 m in the 6MWT overall., Conclusions: Qualified patients who underwent lung transplantation lived longer than those who did not undergo such a procedure. We observed a difference in SLT and DLT recipients., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Primary pulmonary hypertension can lead to hypertrophy of the right ventricle and ultimately to its insufficiency. Lung transplantation remains the only viable treatment for patients with certain forms of this disease. Usage of extracorporeal membrane oxygenation in veno-arterial form (VA-ECMO) after transplantation is both protective for left ventricle (enables adaptation to increased blood flow) and right ventricle (provides time to return to appropriate dimensions and in some cases to correct tricuspid regurgitaion)., Case Presentation: The case study describes 4 patients who were treated with VA-ECMO as a perioperative support. Three patients were diagnosed with idiopathic form of precapillary primary pulmonary hypertension. A fourth patient was a 49-year old woman diagnosed with hypoplastic pulmonary veins representing the postcapillary form of pulmonary hypertension. In all of the cases, VA-ECMO was introduced during the surgery (femoral vein/internal jugular vein and femoral artery) and maintained for several days after the transplantation. Regular echocardiographic and biochemical assessment in postoperative course revealed that cardiac function improved during and after such treatment among all patients. They were successfully weaned off ECMO and finally surgically explanted without any local complications. One patient was treated with awake ECMO protocol., Conclusions: VA-ECMO was proved to be a useful tool during the transplantation and postoperative period. It helps to restore proper cardiac function, as well as prevent adverse effects of aforementioned pathologic changes of a heart., (Copyright © 2020 The Authors. Published by Elsevier Inc.

- Abstract
Background: Interstitial lung diseases (ILDs) are a heterogeneous group of more than 200 diseases manifested by progressive exercise dyspnea, radiological lung changes, and ventilation restrictive disorders. ILDs are the second most common indication for lung transplantation (LTx). Our study group consisted of 139 patients who qualified for LTx at the Silesian Center for Heart Diseases between 2004 and 2018. Of the 139, 92 patients died while on the waiting list, and 47 patients underwent LTx. Medical records including laboratory test results, spirometry, and the 6-minute walk test (6MWT) were analyzed to determine eligibility for LTx. We also assessed quality of life post-LTx., Results: Patients who qualified for LTx showed decreased values of parameters measured by spirometry (43.69 ± 19.05% of forced expiratory volume in the first second [FEV1] and 43.07 ± 20.55% of forced vital capacity [FVC] and severe desaturation during the 6MWT (SpO
2 = 88.78% before 6-minute walk test and 73.23% after the test). After LTx, longer distances were achieved in the 6MWT (235.47 ± 159.57 m during qualification vs 533.2 ± 34.15 m 12 months after LTx) and increased values of spirometry. On average, patients had stopped working 6 years prior to LTx., Conclusion: There is no effective medical treatment for patients with end-stage ILDs. Therefore, lung transplantation is a lifesaving procedure for patients that also extends patients' lives and improves their quality of life., (Copyright © 2020 The Authors. Published by Elsevier Inc.

- Abstract
Background: Lung transplantation remains the only viable option for patients with end-stage lung diseases. However, due to an insufficient number of lung donors, many potential candidates die without undergoing the procedure. In the cases of some patients, bridges to transplantation can be implemented. One such method is extracorporeal membrane oxygenation (ECMO), which, depending on the type, has the ability to replace patients' circulatory and respiratory function., Case Presentation: This case study describes 4 cases of patients, who were successfully bridged to lung transplantation. The first patient developed respiratory failure as a result of acute pulmonary embolisms. His respiratory function was insufficient and he had ECMO implanted for 84 days until he was transplanted. Another patient presented respiratory failure due to massive bleeding, which occurred during transbronchial lung biopsy. Such event led to extensive exacerbation, which resulted in using ECMO as a bridge to recovery at first, but later a bridge to lung transplantation. The patient became a lung graft recipient after 14 days on ECMO. The third patient was a woman who developed severe respiratory failure during the course of the progression of her underlying disease. She was treated with ECMO for 14 days as well, and she also underwent lung transplantation. The fourth patient was qualified for retransplantation. She was bridged to retransplantation via veno-venous ECMO., Conclusion: ECMO can be used a bridge to lung transplantation for suitable patients even for a long period of time, given that it is maintained in accordance with the guidelines., (Copyright © 2020 The Authors.

- Abstract
Background: Lung transplant remains the only viable treatment for most of the end-stage lung diseases. It is believed that extending criteria for donor lungs would increase the number of lung transplants. The aim of the study was to compare the graft function by means of oxygenation index among recipients who received the lungs from donors of extended criteria with those whose received lungs from donors who met the standard criteria., Methods: This retrospective study analyzed 71 donors whose lungs where transplanted into 71 first-time double lung recipients of 2 groups: patients who received transplants before and after 2018. The objective was to assess whether there is a significant difference in quality of the donor pool after applying extended criteria. The second objective was to compare results of recipients with lungs from donors of oxygenation index > 400 mm Hg with those obtained among recipients with this parameter < 400 mm Hg., Results: In the case of transplants performed in 2018 to 2019, oxygenation indices were significantly lower in donors but significantly higher in recipients on the first day than those observed in 2015 to 2017. The number of transplants increased from 9 per year to 22 per year. Irrespective of whether the donor had PaO
2 /fraction of inspired oxygen above or below 400 mm Hg, recipients showed similar oxygenation index values after transplant (mean oxygenation index, 462 vs 412 mm Hg, respectively). Short-term mortality did not differ either., Conclusions: Extended criteria of lungs suitability as a potential grafts not only increases the donor pool but also proves that suboptimal donors are not associated with producing inferior results of the recipients., (Copyright © 2020 The Authors.

- Abstract
Background: Lung transplant is a surgical procedure for end-stage lung disease. Many factors related to lung donors influence the outcome of transplant. The main aim of this single-center study was to assess which donor-related and procedure-related factors would influence the 30-day or hospital mortality of the recipients., Methods: This retrospective study group consisted of 110 donor-recipient pairs undergoing lung transplant between 2012 and 2017 (group 1) and 2018 and 2019 (group 2) in Silesian Center for Heart Diseases. Both groups of donor- and procedure-related factors were included in the analysis: oxygenation index at reporting of the donor, time donor spent in the intensive care unit (ICU), presence of cardiac arrest while being in the ICU, donor age, type of transplant, cumulative ischemia time, duration of the operation, and time of mechanical ventilation., Results: The type of surgery was significantly associated with an increase in the chance of death within 30 days. Patients who underwent single lung transplant had a 20.217 times greater chance of dying within 30 days than patients after double lung transplant (interquartile range, 2.116-193.125)., Conclusions: Single lung transplant increases the risk of death during the first 30 days after lung transplant, and using lungs from older donors may increase the rate of hospital mortality. Oxygenation index, sudden cardiac arrest of the donors, and donor time spent in the ICU do not impact the short-term mortality of lung graft recipients., (Copyright © 2020 The Authors.

- Abstract
Background: Lung transplant remains the only viable treatment for certain patients with end-stage lung diseases. Such patients can become either single or double lung recipients. The 2 procedures are associated with specific risks and benefits. The aim of the study was to assess the survival of patients after lung transplant in a single center., Methods: The retrospective study consists of 128 lung transplant recipients. Patients underwent transplant between 2004 and 2017 because of following diseases: chronic obstructive pulmonary disease (28.2%), cystic fibrosis (26.5%), and primary pulmonary hypertension (12.3%), including idiopathic pulmonary arterial hypertension and interstitial lung diseases (33%). Patients with idiopathic pulmonary arterial hypertension were not treated with postoperative extracorporeal membrane oxygenation as left heart conditioning., Results: Regardless of underlying disease, 75% of DLT recipients and 51% of SLT recipients reached 5-year survival (P = .0066). A total of 87% of lung transplant recipients with cystic fibrosis reached 1-year survival. Among lung recipients with primary pulmonary hypertension who underwent DLT and SLT, 5-year survival was reached by 84% and 51%, respectively (P = .025). Among patients with chronic obstructive pulmonary disease, 82% of DLT recipients and 62% of SLT recipients reached 1-year survival (P = .22). Patients who received transplants because of primary pulmonary hypertension presented the worst short-term survival among all SLT recipients., Conclusions: Patients with CF have the best overall survival among all lung transplant recipients. Double lung transplant provides statistically significantly better outcomes than single lung transplant. This observation is also present among recipients who underwent transplant because of primary pulmonary hypertension, as single lung transplant is not recommended among such patients in particular., (Copyright © 2020 The Authors.

- Abstract
Background: Lung transplant (LTx) is a procedure associated with risk of complications related to airway stenosis that can be treated with bronchoscopic interventions (BIs). The aim of the study was to assess the frequency and risk factors associated with increased need of bronchial interventions in the post-transplant period., Methods: The retrospective study reviewed cases of 165 patients (63 women) who underwent LTx from April 2013 to June 2019. For dichotomous discrete variables (occurrence or lack of intervention) multivariate logistic regression analysis was performed to assess the aforementioned risk factors., Results: BIs were required among 38.55% of lung recipients (n = 65). The number of interventions/patient/y decreases between years 1 and 2 (P < .001), 2 and 3 (P = .013), and 3 and 4 (P < .001); after the fourth year post LTx the differences are not statistically significant. Each 1 mm Hg above 25 mm Hg of mean pulmonary arterial pressure causes statistically significant elevation in the number of interventions by 0.7% in the first year after the procedure. The number of BIs per patient among lung recipients who received a transplant because of idiopathic pulmonary arterial hypertension was statistically significantly higher compared with patients with another underlying lung disease., Conclusions: Airway complications developed in the post-transplant period caused a significant number of patients to be in need of BI, especially balloon bronchoplasty. The highest number of interventions occurred within the first year after LTx, and BI decreases over time. Mean pulmonary arterial pressure measured during qualification may have the ability to predict whether the patient would require BI after LTx., (Copyright © 2020 The Authors.

- Abstract
Introduction: Long-term outcomes of airway complications (AC) after lung transplantation are unknown. The incidence of AC varies from 1.6% to 32% with the related mortality rate of 2% to 4%. The management of most AC is based on endobronchial methods, including balloon bronchoplasty, endobronchial stent placement, and ablative techniques. The aim of the study was to assess the connection between airway complications treated by bronchial intervention (BI) and the survival of lung transplant recipients., Materials and Methods: The single-center retrospective study reviewed the cases of 165 patients (63 women [38.18%], 103 men [61, 82%]; median age at referral for lung transplantations (LTx), 41 years [range, 15-68 years]). The cohort was stratified into 2 groups comprising those whose procedures were complicated by ACs and those without. The primary outcome measured was mortality, with survival endpoints calculated at 6 months., Results: The comparison of the survival of recipients regarding underlying disease (cystic fibrosis [CF], chronic obstructive pulmonary disease [COPD], idiopathic pulmonary artery hypertension [IPAH], and others) with the use of the Kaplan-Meier estimator indicated that the only statistically significant (P = .0194) differences between patients who underwent BI and patients without BI performed were observed in CF patients (Fig 1). In any other diagnosis, the results were not statistically significant (P > .05)., Conclusions: Bronchoscopic intervention because of airway complications after lung transplantation are often-used procedures, but they have no impact on the survival of patients with cystic fibrosis., (Copyright © 2020 The Authors.

- Abstract
Background: Model for End-Stage Liver Disease (MELD) score is used to assess the severity of chronic liver disease. It is implemented in transplantology in the process of qualification for urgent liver transplant. The aim of our study was to assess the liver function of patients qualified for lung transplant using MELD score, taking under consideration mean pulmonary artery pressure as an important risk factor of death., Methods: The study group consisted of 123 patients qualified for lung transplant in Silesian Center for Heart Diseases between 2004 and 2017. Data relevant for MELD score calculations and medial pulmonary artery pressure were acquired from medical records., Results: The average MELD score among patients qualified for lung transplant was 8.24 points, and mean pulmonary pressure (mPAP) was 35.02 mm Hg. Patients with idiopathic pulmonary artery hypertension acquired the highest MELD and highest mPAP results (13.1 points and 57.7 mm Hg, respectively). Patients with idiopathic pulmonary fibrosis presented higher mean MELD-Na score among those with pulmonary arterial hypertension than those without pulmonary arterial hypertension (36.59 mm Hg; 7.74 points vs 18 mm Hg; 6.5 points). There is strong positive correlation between MELD-Na and mPAP among patients who underwent lung transplant because of idiopathic pulmonary fibrosis., Conclusions: This is the first study in the worldwide literature assessing MELD-Na as a predictor of survival among patients qualified for lung transplant and those who already are recipients. Further studies regarding this issue are required as authors will explore this issue in the future., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)
