Abstract Background The diagnosis of acute cellular rejection (ACR) is a major objective in the management of heart transplant recipients. The aim of this study was to assess the utility of speckle-tracking derived parameters in identifying patients at risk of graft rejection. Methods A prospective, single-center study was carried out involving 45 consecutive heart transplant patients who underwent a total of 220 routine endomyocardial biopsies (EMBs) with correlative echocardiographic examination. Results No significant ACR (grade 0-1R) was seen in 190 biopsies (81.2% of the ACR-free group), and moderate ACR requiring specific treatment (grade 2R) was detected in 30 biopsies (13.6% of the ACR group). Grade 3R was not observed. All longitudinal left ventricular (LV) and right ventricular (RV) strain parameters were greater in the ACR-free group than in patients with ACR, while no differences were observed between radial and circumferential strain parameters. In our analysis, we selected RV free wall longitudinal strain (RV FW) ≤ 16.8% and 4-chamber longitudinal strain (4CH LS) ≤ 13.8%, which related to the presence of ACR requiring treatment. We assigned 1 point for each parameter (minimum 0, maximum 2 points) and derived a new echocardiographic index, the Strain Rejection Score (SRS). Our proposed approach—a combination of the 2 abovementioned indices—for screening patients at risk of ACR ≥ 2R, when expressed by a score 2 points, showed good specificity, strong negative predictive value, and the highest area under the curve. Conclusions Our study demonstrated that combination of 4CH LS and RV FW as a new echocardiographic index, the Strain Rejection Score, can be useful as a noninvasive assessment of ACR during the first year of follow-up after heart transplant. Highlights • Noninvasive detection of rejection is a major objective in the management of heart transplant recipients. • We evaluated a new echocardiographic index, Strain Rejection Score (SRS), in the assessment of cardiac allograft rejection. • The new index includes RV free wall longitudinal strain and 4-chamber longitudinal strain analysis. • According to our results, SRS is sufficient for use as an auxiliary diagnostic tool for identifying most patients with a high degree of ACR suspicion.

- Abstract
Background: Graft vasculopathy is a leading cause of death after heart transplantation (HTx). Diagnosing cardiac allograft vasculopathy (CAV) within this patient group poses significant challenges. This study aimed to evaluate the safety and efficacy of coronary computed tomographic angiography (CCTA) in patients after HTx., Methods: We enrolled 107 consecutive HTx recipients (26 women, mean age 50 ± 17 years); all were ≥3 years post-HTx with minimal or no evidence of CAV in a prior coronary angiography performed a minimum of 2 years before the current examination. The inclusion criteria comprised an estimated glomerular filtration rate (eGFR) of ≥30, absence of new heart failure symptoms, and no contraindications to iodine contrast or CT scans. All patients underwent a 64-slice CCTA. In cases of minimal or no changes, noninvasive follow-up examinations were conducted. Significant changes in CT prompted additional coronary angiography., Results: Of the enrolled participants, 9 exhibited minimal changes; 98 displayed no changes in coronary angiography. The median time since transplant was 7 years, with IQR of 4 to 11.25 years. Significant changes were excluded in 98 patients. Among the 9 patients with suspected significant CAV, significant changes were confirmed in 8 patients, resulting in percutaneous transluminal coronary angioplasty (PTCA) performed in 6. One patient from this group died shortly after PTCA. No cardiovascular incidents were observed within the remaining group. The median follow-up period was 539 (IQR = 289-654 days). The mean left ventricular ejection fraction at follow-up was 58% ± 5% compared with 58% ± 4% at baseline. At follow-up, the mean eGFR was 64 ± 18 mL/kg/1.73 m
2 compared with the baseline value of 67.2 mL/kg/1.73 m2 ., Conclusions: CCTA appears to offer a secure and efficient means of assessment in HTx recipients., Competing Interests: Declaration of competing interest All the authors declare no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

- Abstract
Objective: To evaluate the safety, feasibility and effectiveness of minimally invasive HeartMate 3 LVAD implantation., Methodology: Forty-seven patients who underwent the HeartMate 3 LVAD implantation by sternotomy and 26 ones who had implantation via minimally invasive method were analyzed. The observation lasted from November 2016 to May 2020., Results: ECMO as a bridge to LVAD, was more usual in the sternotomy group (11% vs 0%, P = .03). In the minimally invasive group, a history of previous cardiac surgery was more common (54% vs 12%, P < .001), this was the main indication for a minimally invasive approach in our institution. Patients undergoing a minimally invasive implantation had a significantly longer duration of surgery (Med. = 367.5 min vs Med. = 265.0 minutes, P < .001), and significantly higher intraoperative use of fresh frozen plasma (FFP) and platelet concentrates (PCs). There was no significant difference in the number of postoperative bleedings requiring surgical intervention. Postoperative wound infections were observed significantly more often in the sternotomy group (6% vs 0.0%, P < .001). There was no significant difference in survival between groups in the first 180 days after surgery. A slightly lower percentage of patients reached 2-year postsurgery survival in the group undergoing sternotomy, but this finding was not statistically significant. The mean survival time among sternotomy patients was 430.0 days (+/- 291.77 days) vs 633.15 days (+/- 426.84) in minimally invasive group., Conclusions: Minimally invasive implantation of the HeartMate 3 LVAD may be an alternative method of LVAD implantation in a selected group of patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
Objective: To evaluate the impact of heart donors and recipients parameters on the outcomes after orthotopic heart transplantation (OHT)., Methodology: Two hundred fifteen patients who underwent OHT from 2020 to 2023 were analyzed., Results: Average donors age 36.3 (±13.1) years, 74 women (34.42%), BMI 25.3 (±4.99), Na+ concentration 153.7 (±11.8) mmol/L. Mean intraventricular septum thickness 10.0 (±2.2) mm, left ventricular end-diastolic diameter 44.3 (±6) mm, ejection fraction 60.3 (±7.92) %. Median procalcitonin was 0.6 ng/mL. Levonor was used in 75.8%, Empressin in 4.2%, Dopamine in 5.1%, Dobutamine in 3.7%, and Adrenaline in 3.7% of donors. The most common cause of death: intracranial injury (34.42%). Cardiopulmonary resuscitation occurred in 34%, alcoholism in 20.9%, nicotinism in 16.3%, and drug addiction in 7.4% of donors. Mean aortic cross-clamping time was 200.3 (±48.8) minutes. Intra-aortic balloon pump (IABP) after OHT required 6.1%, extra corporeal membrane oxygenation (ECMO) 6.1%, and renal dialysis 36% of recipients. The 1-year mortality rate was 19.1%. Death after OHT correlated with: longer aortic cross-clamping time (207.6 vs 198.59 minutes, P = .292), longer extracorporeal circulation time (196.3 vs 186.47 minutes, P = .335), lower Empressin dose (median 0.01 vs 0.02 j.m/min, P = .03) in donors, longer postoperative mechanical ventilation (mean 101.46 vs 23.09 hours, P = .001), more frequent dialysis, IABP or ECMO (P = .001) and older age of the recipient (51.2 vs 44.8 years, P = .014). Previous cardiac surgery or any surgical intervention after transplantation significantly influenced mortality. The remaining donor factors had no impact on the OHT result., Conclusions: Identification of risk factors in the donor and recipient may improve treatment outcomes after OHT., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

- Abstract
BioGlue is one of the best-known substances used as a tissue adhesive during surgical procedures, especially in cardiac surgery. Inappropriate use of BioGlue can result in inflammation in both the heart and adjacent tissues after its intraoperative application. Inflammation caused by BioGlue in cardiac surgery is a topic that has been discussed by numerous authors in scientific studies, meta-analyses and evaluations of this tissue adhesive. However, there is a lack of collected knowledge on this subject in a single concise article. The purpose of this paper is to review the current medical knowledge on the use of BioGlue in cardiac surgery versus the induction of an inflammatory response. Our paper discusses the details of this problem according to the most recent scientific reports., Competing Interests: The authors report no conflict of interest., (Copyright: © 2024 Polish Society of Cardiothoracic Surgeons (Polskie Towarzystwo KardioTorakochirurgów) and the editors of the Polish Journal of Cardio-Thoracic Surgery (Kardiochirurgia i Torakochirurgia Polska).)

- Abstract
Despite significant advancements in pharmacological treatment, interventional and surgical options are still viable treatments for patients with pulmonary arterial hypertension (PAH), particularly idiopathic PAH. Herein, we review the interventional and surgical treatments for PAH. Atrial septostomy and the Potts shunt can be useful bridging tools for lung transplantation (Ltx), which remains the final surgical treatment among patients who are refractory to any other kind of therapy. Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) remains the ultimate bridging therapy for patients with severe PAH. More importantly, VA-ECMO plays a crucial role during Ltx and provides necessary left ventricular conditioning during the initial postoperative period. Pulmonary denervation may potentially be a new way to ensure better transplant-free survival among patients with the aforementioned disease. However, high-quality randomized controlled trials are needed. As established, obtaining the Eisenmenger physiology among patients with severe pulmonary hypertension by creating artificial defects is associated with improved survival. However, right-to-left shunting may be harmful after Ltx. Closure of the artificially created defects may carry some risk associated with cardiac surgery, especially among patients with Potts shunts. In conclusion, PAH requires an interdisciplinary approach using pharmacological, interventional, and surgical modalities.

- 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
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
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
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.

- Abstract
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.)

- Abstract
Background: Lung transplantation (LTx) is the only treatment for patients with end-stage lung disease. This procedure is associated with a risk of complications related to airway stenosis, which can be treated by means of bronchoscopic interventions (BI). Microbiological colonization may have an impact on airway complications. The aim of the study was to investigate the effect of presence of microbiological pathogens in graft among lung recipients and frequency of BI, considered as the indicator of severe complications., Materials and Methods: The study design was single-center retrospective cohort research; cases of 116 patients with complete microbiological data who underwent LTx from April 2013 to June 2019 were reviewed (70.3% of transplanted patients). All statistical analyses were performed with SPSS version 25.0 and R 3.5.3. For analyses involving the number of bronchoscopy interventions, univariate and multivariate Poisson regression were used. Interaction effect of variables in multivariate Poisson regression was assessed with partial response plot., Results: The mean number of pathogens colonizing each patient was approximately 4.66 (range, 0 to 19) with Candida albicans (n = 42, 36.2%), Aspergillus spp. (n = 33, 28.4%), Pseudomonas aeruginosa (n = 32, 27.59%), and methicillin-sensitive Staphylococcus aureus (MSSA) (n = 29, 25%) being the most prominent. Microbiological agents causing the greatest increase in the risk of intervention are as follows: Proteus mirabilis by 3.84 times, Aspergillus spp. by 3.53 times, and Stenotrophomonas maltophilia by 3.09 times. Burkholderia multivorans, Enterococcus spp., and Klebsiella spp. do not have a statistically significant impact on the number of BI., Conclusions: Some pathogens increase the frequency of complications, which are associated with deterioration of the general condition. Therefore, patients should be monitored for the presence of pathogens in the airways., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
Antibiotic use and microbial resistance in health care-associated infections are increasing globally and causing health care problems. Intensive Care Units (ICUs) represent the heaviest antibiotic burden within hospitals, and sepsis is the second noncardiac cause of mortality in ICUs. Optimizing appropriate antibiotic treatment in the management of the critically ill in ICUs became a major challenge for intensivists. We performed a surveillance study on the antibiotic consumption in 108 Polish ICUs. We determined which classes of antibiotics were most commonly consumed and whether they affected the length of ICU stay and the size and category of the hospital. A total of 292.389 defined daily doses (DDD) and 192.167 patient-days (pd) were identified. Antibiotic consumption ranged from 620 to 3960 DDD/1000 pd. The main antibiotic classes accounted for 59.6% of the total antibiotic consumption and included carbapenems (17.8%), quinolones (14%), cephalosporins (13.7%), penicillins (11.9%), and macrolides (2.2%), respectively, whereas the other antibiotic classes accounted for the remainder (40.4%) and included antifungals (34%), imidazoles (20%), aminoglycosides (18%), glycopeptides (15%), and polymyxins (6%). The most consumed antibiotic classes in Polish ICUs were carbapenems, quinolones, and cephalosporins, respectively. There was no correlation between antibiotic consumption in DDD/1000 patient-days, mean length of ICU stay, size of the hospital, size of the ICU, or the total amount of patient-days. It is crucial that surveillance systems are in place to guide empiric antibiotic treatment and to estimate the burden of resistance. Appropriate use of antibiotics in the ICU should be an important public health care issue.

- Abstract
BACKGROUND Recent advances in ultrasound strain imaging facilitate more precise monitoring of subtle myocardial changes and thus may allow for more appropriate assessment of myocardium after orthotopic heart transplantation (OHT). This study aimed to explore longitudinal left ventricular (LV) and right ventricular (RV) function by speckle-tracking echocardiography (STE) during a 12-month follow-up period in relation to acute cellular rejection (ACR) degree ≥2R and the response to intense immunosuppressive therapy with intravenous steroids. MATERIAL AND METHODS Forty-five adult heart transplant recipients were prospectively assessed at a single center from January 2016 until June 2017. Echocardiography was performed serially at baseline and together with routine biopsies at 2 weeks and 1, 2, 3, 6, 9, and 12 months after OHT. Changes in graft function were evaluated using STE before and during ACR and in the resolving period of ACR. RESULTS A total of 220 pairs of biopsy specimens and strain recordings were analyzed. Moderate ACR was seen in 30 biopsies (13.6%). In the serial assessment, longitudinal strain parameters of the LV (global and 4-, 2-, 3-chamber longitudinal strain) and RV (global and free wall longitudinal strain) were decreased at baseline and improved significantly (P<0.001) within 12 months after OHT. The degree of improvement was not influenced by ACR. There were no significant differences in circumferential, radial, or longitudinal strain rate, or mechanical dyssynchrony. Reduced LV and RV longitudinal strain was related to ACR degree 2R and increased significantly (P<0.0005) during 3 days of intravenous methylprednisolone therapy. CONCLUSIONS Using the STE technique, we have documented an acute improvement in mechanical myocardial function following ACR steroid therapy and a progressive recovery of LV and RV longitudinal function during the first year after OHT.

- Abstract
Left ventricular assist device (LVAD) thrombosis remains a dreadful complication of mechanical circulatory support, with an incidence of 8-12% depending on the pump type and patient's comorbidities. Fibrinolysis may be considered early in pump thrombosis, but when contraindicated a pump exchange remains the only alternative. This short report documents an emergency LVAD exchange in a 55-year-old man who underwent LVAD (HeartWare Inc) implantation in 2013 as a bridge to transplantation. Four months after the initial surgery, he suffered from a hemorrhagic stroke despite properly managed anticoagulation. On February 17
th , 2017 he was re-admitted with LVAD pump thrombosis. As fibrinolysis was contraindicated, an emergency pump exchange was performed via a limited thoracic incision in order to minimize surgical trauma, reduce intraoperative complications and facilitate immediate post-operative recovery. This report documents the very first LVAD pump exchange as well as the first one performed via a minimally invasive approach in Poland.- Published
