- Abstract
• Normal saline has been considered to have deleterious effects on kidney function. • We compared balanced solution versus saline in off-pump coronary bypass surgery. • The study did not demonstrate a significant difference in acute kidney injury. To determine whether balanced solutions can reduce the incidence of acute kidney injury after off-pump coronary artery bypass surgery compared with saline. Randomized controlled trial. Single tertiary care center. Patients who underwent off-pump coronary artery bypass surgery between June 2014 and July 2020. Balanced solution-based chloride-restrictive intravenous fluid strategy. The primary outcome was acute kidney injury within 7 postoperative days, as defined by the 2012 Kidney Disease: Improving Global Outcomes Clinical Practice Guideline. The incidence of acute kidney injury was 4.4% (8/180) in the balanced group and 7.3% (13/178) in the saline group. The difference was not statistically significant (risk difference, −2.86%; 95% confidence interval [CI], −7.72% to 2.01%; risk ratio, 0.61, 95% CI, 0.26 to 1.43; p = 0.35). Compared with the balanced group, the saline group had higher levels of intraoperative serum chloride and lower base excess, which resulted in a lower pH. In patients undergoing off-pump bypass surgery with a normal estimated glomerular filtration rate, the intraoperative balanced solution-based chloride-restrictive intravenous fluid administration strategy did not decrease the rate of postoperative acute kidney injury compared with the saline-based chloride-liberal intravenous fluid administration strategy.

- Abstract
Wide variations exist in the use of pulmonary artery catheters (PACs) and echocardiography in the field of cardiac surgery. A national survey promoted by the Italian Association of Cardio-Thoracic Anesthesiologists and Intensive Care was conducted. The study occurred in Italian cardiac surgery centers (n = 71). Anesthesiologists-intensivists were enrolled. Anonymous questionnaires were used to investigate the use of PACs and echocardiography in the operating room (OR) and intensive care unit (ICU). A total of 257 respondents (32.2% response rate) from 59 centers (83.1% response rate) participated. Use of PACs seems less common in ORs (median insertion in 20% [5-70] of patients), with slightly higher use in ICUs; in about half of cases, it was the continuous cardiac output monitoring system of choice. Almost two-thirds of respondents recently inserted at least one PAC within a few hours of ICU admission, despite its need being largely preoperatively predictable. Protocols regulating PAC insertion were reported by 25.3% and 28% of respondents (OR and ICU, respectively). Transesophageal echocardiography (TEE) was performed intraoperatively in >75% of patients by 86.4% of respondents; only 23.7% stated that intraoperative TEE relied on anesthesiologists. Tissue Doppler and/or 3D imaging were widely available (87.4% and 82%, respectively), but only 37.8% and 24.3% of respondents self-declared skills in these modalities, respectively; 77.1% of respondents had no echocardiography certification, nor were pursuing certification (various reasons); 40.9% had not attended recent echocardiography courses. Lower PAC use was associated with university hospitals (OR: p = 0.014, ICU: p = 0.032) and with lower interventions/year (OR: p = 0.023). Higher independence in performing TEE was reported in university hospitals (OR: p < 0.001; ICU: p = 0.006), centers with higher interventions/year (OR: p = 0.019), and by respondents with less experience in cardiology (ICU: p = 0.046). Variability in the use of PACs and echocardiography was found. Protocols regulating the use of PACs seem infrequent. University centers use PACs less and have greater skills in TEE. Training and certifications in echocardiography should be encouraged. [ABSTRACT FROM AUTHOR]

Background: The development of acute kidney injury (AKI) post-cardiac surgery significantly increases patient morbidity and healthcare costs. Prior researches have established Syndecan-1 (SDC-1) as a potential biomarker for endothelial injury and subsequent acute kidney injury development. This study assessed whether postoperative SDC-1 levels could further predict AKI requiring kidney replacement therapy (AKI-KRT) and AKI progression. Methods: In this prospective study, 122 adult cardiac surgery patients, who underwent valve or coronary artery bypass grafting (CABG) or a combination thereof and developed AKI within 48 h post-operation from May to September 2021, were monitored for the progression to stage 2–3 AKI or the need for KRT. We analyzed the predictive value of postoperative serum SDC-1 levels in relation to multiple endpoints. Results: In the study population, 110 patients (90.2%) underwent cardiopulmonary bypass, of which thirty received CABG or combined surgery. Fifteen patients (12.3%) required KRT, and thirty-eight (31.1%) developed progressive AKI, underscoring the severe AKI incidence. Multivariate logistic regression indicated that elevated SDC-1 levels were independent risk factors for progressive AKI (OR = 1.006) and AKI-KRT (OR = 1.011). The AUROC for SDC-1 levels in predicting AKI-KRT and AKI progression was 0.892 and 0.73, respectively, outperforming the inflammatory cytokines. Linear regression revealed a positive correlation between SDC-1 levels and both hospital (β = 0.014, p = 0.022) and ICU stays (β = 0.013, p < 0.001). Conclusion: Elevated postoperative SDC-1 levels significantly predict AKI progression and AKI-KRT in patients following cardiac surgery. The study's findings support incorporating SDC-1 level monitoring into post-surgical care to improve early detection and intervention for severe AKI. [ABSTRACT FROM AUTHOR]

Aim Background Design Methods Results Conclusion Reporting Method Patient or Public Contribution To examine the influence of clinical and demographic factors on self‐care behaviour and hospitalization rates among patients with coronary heart disease awaiting coronary artery bypass grafting.Appropriate self‐care behaviour can improve the management of patients with coronary heart disease and reduce hospitalization rates among those awaiting coronary artery bypass graft surgery. However, little is known about the influence of clinical and demographic factors on self‐care or hospitalizations in this population.A cross‐sectional study.A convenience sample of 99 participants diagnosed with coronary heart disease awaiting coronary artery bypass grafting surgery were recruited from an outpatient clinic of a public tertiary hospital in southern Thailand. Data were collected on clinical (left ventricular ejection fraction, symptom severity and comorbid disease) and demographic (age, education level and marital status) factors, self‐care behaviour and hospitalization rates. Path analysis using LISREL was performed to examine the influence of self‐care on hospitalizations, with clinical and demographic factors as moderators.Path analysis showed that clinical and demographic factors accounted for nearly half of the variance (46%) in self‐care, and that self‐care accounted for nearly half of the variance (48%) in hospitalization rates.Our findings demonstrate that clinical and demographic factors play an important role in self‐care behaviour, and in turn hospitalization rates of pre‐coronary artery bypass graft surgery patients. It is suggested that the period pre‐surgery is an ideal time to introduce programmes designed to bolster self‐care and minimize uncertainty among this patient population and that nurses are well‐positioned to do so.Study methods and results reported in adherence to the STROBE checklist.Patients contributed their consent, time and data to the study.

Background: Severe pain occurs after cardiac surgery in the sternum and chest tubes sites. Although analgesia targeting the sternum is often prioritized, the analgesia of the drain site is sometimes overlooked. This study of patients undergoing coronary artery bypass grafting (CABG) aimed to provide optimized analgesia for both the sternum and the chest tubes area by combining parasternal block (PSB) and serratus anterior plane block (SAPB). Methods: Ethics committee approval (E.Kurul-E2-24-6176, 07/02/2024) was received for the study. Then, the trial was registered on www.clinicaltrials.gov (https://clinicaltrials.gov/) under the identifier NCT05427955 on 17/03/2024. Twenty patients between the ages of 18–80, with ASA physical status classification II-III, undergoing coronary artery bypass grafting CABG with sternotomy, were included. While the patients were under general anesthesia, PSB was performed through the second and fourth intercostal spaces, and SAPB was performed over the sixth rib. The primary outcome was VAS (Visual Analog Scale) during the first 12 h after extubation. The secondary outcomes were intraoperative remifentanil consumption and block-related side effects. Results: The average age of the patients was 64 years. Five patients were female, and 15 were male. For the sternum area, only one patient had resting VAS scores of 4, while the VAS scores for resting for the other patients were below 4. For chest tubes area, only two patients had resting VAS scores of 4 or above, while the resting VAS scores for the other patients were below 4. The patients' intraoperative remifentanil consumption averaged 2.05 mg. No side effects related to analgesic protocol were observed in any of the patients. Conclusions: In this preliminary study where PSB and SAPB were combined in patients undergoing CABG, effective analgesia was achieved for the sternum and chest tubes area. [ABSTRACT FROM AUTHOR]

Background: Packed red blood cell (pRBC) transfusion is a relatively safe and mainstay treatment commonly used in cardiac surgical patients. However, there is limited evidence on clinical effects of transfusing blood nearing end-of shelf life that has undergone biochemical changes during storage. Objective: To investigate evidence of associations between morbidity/mortality and transfusion of blood near end of shelf-life (> 35 days) in cardiac surgical patients. Methods: Data from the Queensland Health Admitted Patient Data Collection database 2007–2013 was retrospectively analysed. Coronary artery bypass graft and valvular repair patients were included. Multivariable logistic regression was used to examine the effect of pRBC age (< 35 days vs. ≥ 35 days) on in-hospital mortality and morbidity. As secondary analysis, outcomes associated with the number of pRBC units transfused (≤ 4 units vs. ≥ 5 units) were also assessed. Results: A total of 4514 cardiac surgery patients received pRBC transfusion. Of these, 292 (6.5%) received pRBCs ≥ 35 days. No difference in in-hospital mortality or frequency of complications was observed. Transfusion of ≥ 5 units of pRBCs compared to the ≤ 4 units was associated with higher rates of in-hospital mortality (5.6% vs. 1.3%), acute renal failure (17.6% vs. 8%), infection (10% vs. 3.4%), and acute myocardial infarction (9.2% vs. 4.3%). Infection carried an odds ratio of 1.37 between groups (CI = 0.9–2.09; p = 0.14) and stroke/neurological complications, 1.59 (CI = 0.96–2.63; p = 0.07). Conclusion: In cardiac surgery patients, transfusion of pRBCs closer to end of shelf-life was not shown to be associated with significantly increased mortality or morbidity. Dose-dependent differences in adverse outcomes (particularly where units transfused were > 4) were supported. [ABSTRACT FROM AUTHOR]

Pericardial fluid (PF) has been suggested as a reservoir of molecular targets that can be modulated for efficient repair after myocardial infarction (MI). Here, we set out to address the content of this biofluid after MI, namely in terms of microRNAs (miRs) that are important modulators of the cardiac pathological response. PF was collected during coronary artery bypass grafting (CABG) from two MI cohorts, patients with non-ST-segment elevation MI (NSTEMI) and patients with ST-segment elevation MI (STEMI), and a control group composed of patients with stable angina and without previous history of MI. The PF miR content was analyzed by small RNA sequencing, and its biological effect was assessed on human cardiac fibroblasts. PF accumulates fibrotic and inflammatory molecules in STEMI patients, namely causing the soluble suppression of tumorigenicity 2 (ST-2), which inversely correlates with the left ventricle ejection fraction. Although the PF of the three patient groups induce similar levels of fibroblast-to-myofibroblast activation in vitro, RNA sequencing revealed that PF from STEMI patients is particularly enriched not only in pro-fibrotic miRs but also anti-fibrotic miRs. Among those, miR-22-3p was herein found to inhibit TGF-β-induced human cardiac fibroblast activation in vitro. PF constitutes an attractive source for screening diagnostic/prognostic miRs and for unveiling novel therapeutic targets in cardiac fibrosis. [ABSTRACT FROM AUTHOR]

Background: Despite continuous improvements in revascularization techniques, refractory angina without potential revascularization options remains a relevant clinical issue with significant impact on the patient's quality of life. Recently, a novel device, the Coronary Sinus Reducer (CSR), has been introduced into clinical practice as a therapeutic option for patients with disabling angina pectoris. In this single-center, observational study, we evaluated the mid-term (3-month) safety and efficacy of the CSR in a real-world cohort. Methods: The study population consisted of 55 patients with refractory angina without potential revascularization options, who were predominantly men (87.3%) with a high cardiovascular risk factor burden and advanced angina (baseline CCS angina class 3.15 ± 0.6). In terms of procedure safety, all patients underwent successful device deployment with only one periprocedural complication. Results: At the 3-month follow-up, we observed a statistically significant improvement in angina control measured CCS class and SAQ-7 total questionnaire along with increased abolition of physical limitation—6-MWT (233.3 ± 107.1 vs. 305.2 ± 126.8; p < 0.0001). Additionally, we observed significant improvement in terms of quality of life measurements SF-36, the EQ-5D-5L questionnaire, and the EQ-VAS. Conclusions: Our real-world data suggest that CSR implantation is a relatively safe procedure and appears to be particularly effective in relieving angina symptoms and improving quality of life in subjects with refractory angina.

Background: Postoperative atrial fibrillation (POAF) is one of the most common types of acute AF and can complicate the treatment course of approximately one third of patients undergoing cardiac surgery. Sodium‐glucose cotransporter‐2 (SGLT2) inhibitors are among the newest antidiabetic drugs which can be therapeutic options for preventing POAF by different mechanisms. Methods: Empagliflozin to Prevent POAF (EMPOAF) is an interventional, investigator‐initiated, double‐blind, placebo‐controlled, multicenter, randomized controlled trial which will be conducted in two referral teaching cardiology hospitals in Tehran. Four‐hundred ninety‐two adult patients who are scheduled for elective isolated coronary artery bypass graft (CABG) surgery will be randomly assigned to one of the groups of intervention (empagliflozin 10 mg daily) or placebo starting at least 3 days before surgery until discharge. Key exclusion criteria are a history of diabetes mellitus, AF, ketoacidosis, or recurrent urinary tract infections along with severe renal or hepatic impairment, unstable hemodynamics, and patients receiving SGLT2 inhibitors for another indication. The primary outcome will be the incidence of POAF. Key secondary endpoints will be the composite rate of life‐threatening arrhythmias, postoperative acute kidney injury, hospitalization length, in‐hospital mortality, stroke, and systemic embolization. Key safety endpoints will be the rate of life‐threatening and/or genitourinary tract infections, hypoglycemia, and ketoacidosis. Conclusions: EMPOAF will prospectively evaluate whether empagliflozin 10 mg daily can reduce the rate of POAF in patients undergoing elective CABG. Enrolment into this study has started by November 2023 and is expected to be ended before the end of 2025. [ABSTRACT FROM AUTHOR]

Myocardial revascularization in patients presenting with an anterior mediastinal mass poses considerable challenges. In this report, we outline two cases involving patients with anterior mediastinal masses who underwent surgical resection alongside concurrent myocardial revascularization. One patient underwent coronary artery bypass graft surgery, while the other was treated by percutaneous coronary intervention with drug‐eluting stent placement. Both patients fully recovered from the relative procedures and were discharged within two weeks post‐surgery, ultimately diagnosed with thymoma. The concomitant intervention offered the advantage of promptly addressing both conditions, and it was performed safely through a collaborative multidisciplinary effort. [ABSTRACT FROM AUTHOR]

Background: Minimally invasive direct coronary artery bypass (MIDCAB) grafting is a safe technique for revascularization of the left anterior descending artery. The objective of this study was to evaluate the long-term outcomes of patients who underwent MIDCAB surgery in our institution. This was a retrospective, observational outcome study of retrospectively collected data. Data was collected using community, electronic, and paper medical records as well as telephone follow-up conversations with patients who underwent MIDCAB between December 1996 and June 2021. The primary outcome measure was mortality. Secondary outcomes included revascularization, myocardial infarction, and wound infection. Survival analysis was performed using the Kaplan–Meier method. Results: A total of 215 patients were identified in the study period undergoing MIDCAB at our center. The median age was 77 years, and the cohort consisted of 180 (83.3%) of male patients. The median follow-up period was 16 years (12.1–17.7). At follow-up, freedom from repeat left anterior descending revascularization and from other vessels, revascularization was 96.7% and 89.1% respectively. Survival rates were 99.5%, 81.0%, and 45.2% survival at 1 year, 10 years, and 25 years respectively. Univariate analysis showed age (p < 0.01, Hazard ratio 1.08 confidence interval 1.05–1.11) and left ventricular function (p < 0.01, hazard ratio 2.40, confidence interval 1.66–3.45) as factors associated with mortality. Conclusions: Our single-center experience of MIDCAB demonstrated excellent long-term freedom from revascularization and other complications. Although limited by the retrospective nature, the study shows MIDCAB to be a safe procedure for definitive revascularization of the left anterior descending coronary artery. [ABSTRACT FROM AUTHOR]

We reviewed the cardiac surgical literature for 2023. PubMed displayed almost 34,000 hits for the search term "cardiac surgery AND 2023." We used a PRISMA approach for a results-oriented summary. Key manuscripts addressed the mid- and long-term effects of invasive treatment options in patient populations with coronary artery disease (CAD), comparing interventional therapy (percutaneous coronary intervention [PCI]) with surgery (coronary artery bypass graft [CABG]). The literature in 2023 again confirmed the excellent long-term outcomes of CABG compared with PCI in patients with left main stenosis, specifically in anatomically complex chronic CAD, but even in elderly patients, generating further support for an infarct-preventative effect as a prognostic mechanism of CABG. For aortic stenosis, a previous trend of an early advantage for transcatheter (transcatheter aortic valve implantation [TAVI]) and a later advantage for surgical (surgical aortic valve replacement) treatment was also re-confirmed by many studies. Only the Evolut Low Risk trial maintained an early advantage of TAVI over 4 years. In the mitral and tricuspid field, the number of interventional publications increased tremendously. A pattern emerges that clinical benefits are associated with repair quality, making residual regurgitation not irrelevant. While surgery is more invasive, it currently generates the highest repair rates and longest durability. For terminal heart failure treatment, donor pool expansion for transplantation and reducing adverse events in assist device therapy were issues in 2023. Finally, the aortic diameter related to adverse events and technical aspects of surgery dominated in aortic surgery. This article summarizes publications perceived as important by us. It cannot be complete nor free of individual interpretation, but provides up-to-date information for patient-specific decision-making. [ABSTRACT FROM AUTHOR]

Based on a voluntary registry, founded by the German Society for Thoracic and Cardiovascular Surgery (DGTHG) in 1980, a well-defined but limited dataset of all cardiac and vascular surgery procedures performed in 77 German heart surgery departments is reported annually. For the year 2023, a total of 168,841 procedures were submitted to the registry. Of these operations, 100,606 are defined as heart surgery procedures in a classical sense. The unadjusted in-hospital survival rate for the 28,996 isolated coronary artery bypass grafting procedures (relationship on-/off-pump 2.8:1) was 97.6%; 97.7% for the 39,859 isolated heart valve procedures (23,727 transcatheter interventions included); and 99.2% for 19,699 pacemaker/implantable cardioverter defibrillator procedures. Concerning short and long-term mechanical circulatory support, a total of 2,982 extracorporeal life support/extracorporeal membrane oxygenation implantations and 772 ventricular assist device implantations (left/right ventricular assist device, BVAD, total artificial heart) were reported. In 2023, 324 isolated heart transplantations, 248 isolated lung transplantations, and 2 combined heart–lung transplantations were performed. This annually updated registry of the DGTHG represents nonrisk adjusted voluntary public reporting and encompasses acute data for nearly all heart surgical procedures in Germany.

Objectives: This study aimed to develop machine learning models for risk prediction of continuous renal replacement therapy (CRRT) following coronary artery bypass grafting (CABG) surgery in intensive care unit (ICU) patients. Methods: We extracted CABG patients from the electronic medical record system of the hospital. The endpoint of this study was the requirement for CRRT after CABG surgery. The Boruta method was used for feature selection. Seven machine learning algorithms were developed to train models and validated using 10 fold cross-validation (CV). Model discrimination and calibration were estimated using the area under the receiver operating characteristic curve (AUC) and calibration plot, respectively. We used the SHapley Additive exPlanations (SHAP) method to illustrate the effects of the features attributed to the model and analyze the effects of individual features on the output of the mode. Results: In this study, 72 (37.89%) patients underwent CRRT, with a higher mortality compared to those patients without CRRT. The Gaussian Naïve Bayes (GNB) model with the highest AUC were considered as the final predictive model and performed best in predicting postoperative CRRT. The analysis of importance revealed that cardiac troponin T, creatine kinase isoenzyme, albumin, low-density lipoprotein cholesterol, NYHA, serum creatinine, and age were the top seven features of the GNB model. The SHAP force analysis illustrated how created model visualized individualized prediction of CRRT. Conclusions: Machine learning models were developed to predict CRRT. This contributes to the identification of risk variables for CRRT following CABG surgery in ICU patients and enables the optimization of perioperative managements for patients. [ABSTRACT FROM AUTHOR]

We sought to explore the relationship between various surgeon-related and hospital-level characteristics and clinical outcomes among patients requiring cardiac surgery. We searched the New York State Cardiac Data Reporting System for all coronary artery bypass grafting (CABG) and valve cases between 2015 and 2017. The data were analyzed without dichotomization. Among CABG/valve surgeons, case volume was positively correlated with years in practice (P = 0.002) and negatively correlated with risk-adjusted mortality ratio (P = 0.014). For CABG and CABG/valve surgeons, our results showed a negative association between teaching status and case volume (P = 0.002, P = 0.018). Among CABG surgeons, hospital teaching status and presence of cardiothoracic surgery residency were inversely associated with risk-adjusted mortality ratio (P = 0.006, P = 0.029). There is a complex relationship between case volume, teaching status, and surgical outcomes suggesting that balance between academics and volume is needed. • Among coronary artery bypass grafting/valve surgeons, case volume positively correlated with years in practice. • Major teaching status associated with lower case volume for all case types. • For coronary artery bypass grafting, teaching status inversely associated with risk-adjusted mortality ratio. • Balance between volume and teaching important for outcomes.

Background: Catecholamines and β‐adrenergic receptors (β‐ARs) play an important role in the regulation of cardiac tolerance to the impact of ischemia and reperfusion. This systematic review analyzed the molecular mechanisms of the cardioprotective activity of β‐AR ligands. Methods: We performed an electronic search of topical articles using PubMed databases from 1966 to 2023. We cited original in vitro and in vivo studies and review articles that documented the cardioprotective properties of β‐AR agonists and antagonists. Results: The infarct‐reducing effect of β‐AR antagonists did not depend on a decrease in the heart rate. The target for β‐blockers is not only cardiomyocytes but also neutrophils. β1‐blockers (metoprolol, propranolol, timolol) and the selective β2‐AR agonist arformoterol have an infarct‐reducing effect in coronary artery occlusion (CAO) in animals. Antagonists of β1‐ and β2‐АR (metoprolol, propranolol, nadolol, carvedilol, bisoprolol, esmolol) are able to prevent reperfusion cardiac injury. All β‐AR ligands that reduced infarct size are the selective or nonselective β1‐blockers. It was hypothesized that β1‐AR blocking promotes an increase in cardiac tolerance to I/R. The activation of β1‐AR, β2‐AR, and β3‐AR can increase cardiac tolerance to I/R. The cardioprotective effect of β‐AR agonists is mediated via the activation of kinases and reactive oxygen species production. Conclusions: It is unclear why β‐blockers with the similar receptor selectivity have the infarct‐sparing effect while other β‐blockers with the same selectivity do not affect infarct size. What is the molecular mechanism of the infarct‐reducing effect of β‐blockers in reperfusion? Why did in early studies β‐blockers decrease the mortality rate in patients with acute myocardial infarction (AMI) and without reperfusion and in more recent studies β‐blockers had no effect on the mortality rate in patients with AMI and reperfusion? The creation of more effective β‐AR ligands depends on the answers to these questions. [ABSTRACT FROM AUTHOR]

During coronary artery bypass grafting (CABG), the surgical procedure, particularly the manipulation of the major arteries of the heart, induces a significant inflammatory state that may compromise platelet function to the extent that platelet transfusion is required. Given stored platelets as a major source of biological mediators, this study investigates the effects of platelet transfusion on the major pro‐aggregatory, pro‐inflammatory and immunomodulatory markers of platelets. Platelets from 20 patients, 10 who received platelet transfusion and 10 without, were subjected to flow cytometery where P‐selectin and CD40 ligand (CD40L) expressions and PAC‐1 binding (activation‐specific anti GPIIb/GPIIIa antibody) analysed at five‐time points of 24 h before surgery, immediately, 2 h, 24 h and 1 week after surgery. Analysis of intra‐platelet transforming growth factor‐beta‐1 (TGF‐β1) was also conducted using western blotting. Patients with platelet transfusion showed increased levels of P‐selectin, CD40L and intra‐platelet TGF‐β1 2‐h after surgery compared to those without transfusion (p < 0.05). PAC‐1 binding was increased 24 h after surgery in transfused patients (p < 0.05). Given the significant post‐transfusion elevation of platelet TGF‐β1, P‐sel/CD40L reduction in transfused patients a week after was of much interest. This study showed for the first time the significant effects of platelet transfusion on the pro‐inflammatory, pro‐aggeregatory and immunomodulatory state of platelets in CABG patients, which manifested with immediate, midterm and delayed consequences. While the increased pro‐inflammatory conditions manifested as an immediate effect of platelet transfusion, the pro‐aggregatory circumstances emerged 24 h post‐transfusion. A week after surgery, attenuations of pro‐inflammatory markers of platelets in transfused patients were shown, which might be due to the immunomodulatory effects of TGF‐β1. [ABSTRACT FROM AUTHOR]

Background/Aims: Regulatory guidelines recommend that sponsors develop a risk-based approach to monitoring clinical trials. However, there is a lack of evidence to guide the effective implementation of monitoring activities encompassed in this approach. The aim of this study was to assess the efficiency and impact of the risk-based monitoring approach used for a multicentre randomised controlled trial comparing treatments in paediatric patients undergoing cardiac bypass surgery. Methods: This is a secondary analysis of data from a randomised controlled trial that implemented targeted source data verification as part of the risk-based monitoring approach. Monitoring duration and source to database error rates were calculated across the monitored trial dataset. The monitored and unmonitored trial dataset, and simulated trial datasets with differing degrees of source data verification and cohort sizes were compared for their effect on trial outcomes. Results: In total, 106,749 critical data points across 1,282 participants were verified from source data either remotely or on-site during the trial. The total time spent monitoring was 365 hours, with a median (interquartile range) of 10 (7, 16) minutes per participant. An overall source to database error rate of 3.1% was found, and this did not differ between treatment groups. A low rate of error was found for all outcomes undergoing 100% source data verification, with the exception of two secondary outcomes with error rates >10%. Minimal variation in trial outcomes were found between the unmonitored and monitored datasets. Reduced degrees of source data verification and reduced cohort sizes assessed using simulated trial datasets had minimal impact on trial outcomes. Conclusions: Targeted source data verification of data critical to trial outcomes, which carried with it a substantial time investment, did not have an impact on study outcomes in this trial. This evaluation of the cost-effectiveness of targeted source data verification contributes to the evidence-base regarding the context where reduced emphasis should be placed on source data verification as the foremost monitoring activity.

Left ventricular assist device (LVAD) implantation is an effective alternative treatment to heart transplantation, especially for end‐stage heart failure patients who are ineligible for or unable to await a heart transplant. This report describes a complex and innovative surgery where LVAD implantation was performed alongside multiple concomitant cardiac and aortic procedures. A 62‐year‐old male patient with complicated comorbidities developed acute myocardial infarction and subsequent refractory advanced heart failure. Given his critically ill condition and intractable anatomical malformations, the CH‐VAD left ventricular assist system implantation was performed concomitantly with the Bentall procedure, coronary artery bypass grafting, tricuspid valvuloplasty, and foramen ovale closure. The patient was successfully discharged. This case details the medical decision‐making process and surgical strategy and demonstrates the feasibility of LVAD implantation combined with multiple additional cardiac and aortic procedures in expert cardiac centres. Success relies on experienced cardiac surgeons and a multidisciplinary LVAD Heart Team, ensuring excellence in surgical techniques, preoperative evaluation, post‐operative care, and rehabilitation.

Background: In patients with ST-elevation myocardial infarction (STEMI), either with or without cardiogenic shock, mechanical circulatory support with an intra-aortic balloon pump (IABP) is not associated with lower mortality. However, in STEMI patients undergoing urgent coronary artery bypass grafting (CABG), preoperative insertion of an IABP has been suggested to reduce mortality. In this study, the effect of preoperative IABP use on mortality in STEMI patients undergoing urgent CABG was investigated. Methods: All consecutive STEMI patients undergoing urgent CABG in a single centre between 2000 and 2018 were studied. The primary outcome, 30-day mortality, was compared between patients with and without a preoperative IABP. Subgroup analysis and multivariable analysis using a propensity score and inverse probability treatment weighting were performed to adjust for potential confounders. Results: A total of 246 patients were included, of whom 171 (69.5%) received a preoperative IABP (pIABP group) and 75 (30.5%) did not (non-pIABP group). In the pIABP group, more patients suffered from cardiogenic shock, persistent ischaemia and reduced left ventricular function. Unadjusted 30-day mortality was comparable between the pIABP and the non-pIABP group (13.3% vs 12.3%, p = 0.82). However, after correction for confounders and inverse probability treatment weighting preoperative IABP was associated with reduced 30-day mortality (relative risk 0.52, 95% confidence interval 0.30–0.88). Conclusion: In patients with STEMI undergoing urgent CABG, preoperative insertion of an IABP is associated with reduced mortality. [ABSTRACT FROM AUTHOR]

Objective Methods Results Conclusions People living with HIV have an increased risk of heart failure (HF). There are different subtypes of HF. Knowledge about the factors differentiating HF subtypes in people with HIV is limited but necessary to guide preventive measures and treatment.A retrospective review of medical records was undertaken in people with HIV aged ≥18 years who received care at the University of Miami/Jackson Memorial HIV Clinic between January 2017 and November 2019 (N = 1166). Patients with an echocardiogram available for review (n = 305) were included. HF was defined as a documented diagnosis of any HF subtype (n = 52). We stratified those with HF by their ejection fraction (EF) into HF with preserved EF (HFpEF), HF with borderline EF, or HF with reduced EF (HFrEF).The prevalence of HF was 4.5%. The cohort included 46.2% females and 75% self‐identified African Americans. Those with HF had a higher prevalence of hypertension, prior myocardial infarction, angina, coronary artery disease, percutaneous coronary intervention, coronary artery bypass grafting, diastolic dysfunction, and left ventricle hypertrophy. People with HIV with HF with borderline EF exhibited more coronary artery disease than those with HFpEF.We characterize HF in people with HIV in South Florida and report the prevalence of HF and HF subtypes. Only a small percentage of patients had echocardiograms performed, suggesting an ongoing need for recognition of the increased risk of HF in people living with HIV, and raising the concern about lack of awareness contributing to underdiagnosis and missed treatment opportunities in this population.

Early invasive revascularization guided by moderate to severe ischemia did not improve outcomes over medical therapy alone, underlying the need to identify high-risk patients for a more effective invasive referral. CMR could determine the myocardial extent and matching locations of ischemia and infarction. This study sought to investigate if CMR peri-infarct ischemia is associated with adverse events incremental to known risk markers. Consecutive patients were included in an expanded cohort of the multicenter SPINS (Stress CMR Perfusion Imaging in the United States) study. Peri-infarct ischemia was defined by the presence of any ischemic segment neighboring an infarcted segment by late gadolinium enhancement imaging. Primary outcome events included acute myocardial infarction and cardiovascular death, whereas secondary events included any primary events, hospitalization for unstable angina, heart failure hospitalization, and late coronary artery bypass surgery. Among 3,915 patients (age: 61.0 ± 12.9 years; 54.7% male), ischemia, infarct, and peri-infarct ischemia were present in 752 (19.2%), 1,123 (28.8%), and 382 (9.8%) patients, respectively. At 5.3 years (Q1-Q3: 3.9-7.2 years) of median follow-up, primary and secondary events occurred in 406 (10.4%) and 745 (19.0%) patients, respectively. Peri-infarct ischemia was the strongest multivariable predictor for primary and secondary events (HR adjusted : 1.72 [95% CI: 1.23-2.41] and 1.71 [95% CI: 1.32-2.20], respectively; both P < 0.001), adjusted for clinical risk factors, left ventricular function, ischemia extent, and infarct size. The presence of peri-infarct ischemia portended to a >6-fold increased annualized primary event rate compared to those with no infarct and ischemia (6.5% vs 0.9%). Peri-infarct ischemia is a novel and robust prognostic marker of adverse cardiovascular events. [ABSTRACT FROM AUTHOR]

The use of revascularization (coronary artery bypass surgery [CABG] and percutaneous coronary intervention [PCI]) in the United States is declining, but they remain important procedures for the treatment of patients with coronary artery disease. There are large and long‐standing disparities in the use of revascularization among patients hospitalized with heart disease. In this article, we investigate whether the implementation of the Patient Protection and Affordable Care Act (ACA) is associated with a reduction in disparities in the use of revascularization. We use data from the Agency for Healthcare Research and Quality (AHRQ)'s National Inpatient Sample (NIP) of the Healthcare Cost and Utilization Project (HCUP) project to compare the use of revascularization among patients 45 years and older in the United States in 2012 and 2018. For both years, we conducted multiple logistic regression analysis to assess the factors associated with coronary revascularization among patients hospitalized with heart disease. Hospitalizations for heart disease and the use of revascularization both fell between 2012 and 2018 at a rate that was greater than the reduction in heart disease deaths in the country. These findings are consistent with the clinical literature on the growth of medical management of heart disease. Disparities in the use of revascularization, by gender, insurance status, neighborhood, and race/ethnicity, were just as large after the implementation of the ACA in 2014. The expansion of insurance by the ACA, alone, was insufficient to reduce disparities in the use of revascularization in patients with diagnosed coronary heart disease in the United States.

Background Method Results Conclusion The aim of this study was to determine the effects of nursing education and counselling provided by telephone to individuals undergoing coronary artery bypass graft surgery on their discharge satisfaction levels and self‐care power levels.The study was conducted using a randomized controlled experimental research model with a pre‐test‐post‐test control group (30 individuals in the experiment group and 30 individuals in the control group). Routine nursing care was applied to the patients in the control group throughout their attendance, and no training or intervention was made after discharge. By contrast, in addition to routine nursing care, the for 4 weeks in the experimental group received nursing education and counselling services by phone in the post‐discharge period. A ‘Personal Information Form,’ ‘Discharge Training Satisfaction Scale,’ and ‘Self‐Care Strength Scale,’ which were prepared by the researchers and included the personal information of the patients, were used to collect the data.The difference between the pre‐test self‐care power scale and discharge education satisfaction scale sub‐dimensions of the groups and the mean score of the total score was not statistically significant. The post‐test self‐care power scale and discharge education satisfaction scale sub‐dimensions and total score averages of the patients in the experimental group were higher than in the control group, and the difference between them was statistically significant (P <0.05).The nursing education and counselling services given to the patients on the phone increased their self‐care skill levels and discharge satisfaction levels.

Background: Although the usefulness of pulmonary function tests has been established for lung resection and coronary artery bypass surgeries, the association between preoperative pulmonary function test and postoperative respiratory complications in nonpulmonary and noncardiac surgery is inconclusive. The purpose of this study was to determine the association between preoperative forced expiratory volume in one second (FEV1) on pulmonary function test and the development of postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery. Methods: Adult patients aged ≥ 18 years and who underwent nonpulmonary and noncardiac surgery with expected moderate to high risk of perioperative complications from June 2012 to March 2019 were included. The primary exposure was preoperative FEV1 measured by pulmonary function test within six months before surgery. The primary outcome was respiratory failure (i.e., invasive positive pressure ventilation for at least 24 h after surgery or reintubation) and/or death within 30 days after surgery. A logistic regression model was used to adjust for the respiratory failure risk index, which is a scoring system that predicts the probability of postoperative respiratory failure based on patient and surgical factors, and to examine the association between preoperative FEV1 and the development of postoperative respiratory failure and/or death. Results: Respiratory failure and/or death occurred within 30 days after surgery in 52 (0.9%) of 5562 participants. The incidence of respiratory failure and/or death in patients with FEV1 ≥ 80%, 70%– < 80%, 60%– < 70%, and < 60% was 0.9%, 0.6%, 1.7%, and 1.2%, respectively. Multivariable logistic regression analysis showed no significant association between preoperative FEV1 and postoperative respiratory failure and/or death (adjusted odds ratio per 10% decrease in FEV1: 1.01, 95% confidence interval: 0.88–1.17, P = 0.838). Addition of FEV1 information to the respiratory failure risk index did not improve the prediction of respiratory failure and/or death [area under the receiver operating characteristics curve: 0.78 (95% confidence interval: 0.72–0.84) and 0.78 (95% confidence interval: 0.72–0.84), respectively; P = 0.84]. Conclusion: We found no association between preoperative FEV1 and postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery.

Background and Objectives Materials and Methods Results Conclusion By optimizing erythropoiesis, patient blood management (PBM) programmes can reduce transfusions, lower mortality and provide cost‐effective care. While definitions of anaemia have historically varied by sex, for the purposes of PBM, anaemia is defined as a haemoglobin <130 g/L. Our objective was to describe whether perioperative anaemia and transfusion rates in the PBM setting vary by sex.We conducted a retrospective study of the Ontario Nurse Transfusion Coordinators Program (ONTraC) database from 2018 to 2022. ONTraC collects data from 25 Ontario hospitals which together account for >70% of Ontario's provincial blood use (~400,000 units per year). We collected data on patients undergoing elective isolated coronary artery bypass graft surgery (CABG), open heart valve replacement, CABG plus valve replacement, single‐knee arthroplasty and single‐hip arthroplasty.From 2018 to 2022, 17,700 patients were included in the ONTraC program; 47% were females (N = 8376). Across almost all years and procedures, females were found to have a significantly lower pre‐operative, nadir and discharge haemoglobin as compared with males, irrespective of PBM interventions. Transfusion rates were significantly higher for females; this was most pronounced in cardiac surgery.Females experienced more perioperative anaemia and higher transfusion rates. Historic sex‐specific definitions of anaemia may contribute to a greater tolerance of anaemia in females. Prioritizing females for multimodal PBM and consistently achieving a pre‐operative haemoglobin >130 g/L may reduce the amount of red blood cell (RBC) transfusions that female patients receive.

CORONARY artery bypass , *INDIGENOUS Australians , *RED blood cell transfusion , *CARDIOPULMONARY bypass - Abstract
Introduction Methods Results Conclusion The ‘gap’ continues to exist between the Indigenous and non‐Indigenous populations within Australia, with Indigenous Australians continuing to experience poorer health outcomes, and a reduced life expectancy of 10.6 years for males and 9.5 for females. Indigenous Australians are far more likely to suffer from ischaemic heart disease. We sought to investigate the outcomes of Indigenous Australians undergoing isolated coronary artery bypass graft surgery (CABG) at a single institution.A retrospective cohort study comparing Indigenous with non‐Indigenous Australians from prospectively collected data were performed for all patients who underwent isolated CABG at a single centre between 2015 and 2018. The primary endpoint was 30‐day mortality with secondary endpoints including deep sternal wound infection, new renal failure, length of stay, stroke and rate of readmission.A total of 905 patients were included in the study. The Indigenous cohort had 130 patients and the non‐Indigenous cohort contained 775 patients. The baseline preoperative characteristics were significantly different between the two cohorts, with Indigenous patients younger (55.7 vs. 64.6 years), more likely to be female (33.1% vs. 16.4%) and to be dialysis‐dependent (10% vs. 1.2%). The primary outcome was more likely in Indigenous Australians, with a 30‐day mortality rate of 3.1% compared with 0.8%. There was a higher incidence of new renal failure (12.3% vs. 5.9%), red blood cell transfusion (30% vs. 20.8%).Indigenous patients undergoing CABG at our institution have significantly more co‐morbidities as well as worse post‐operative outcomes and strategies to address this are urgently required.

This article provides a summary of several studies on various topics related to cardiovascular care. One study focuses on ventricular septal defects (VSDs) that occur after acute myocardial infarction (AMI), discussing the diagnosis, consequences, and treatment strategies for VSDs. Another study explores the increased risk of heart failure in patients with inflammatory bowel disease (IBD), finding that IBD patients have a moderately higher risk of developing heart failure for at least 20 years after diagnosis. The article also discusses the use of a point-of-care high-sensitivity cardiac troponin I (hs-cTnI) assay to assess patients with suspected AMI, finding that this assay can effectively and safely assess the risk of AMI. Additionally, the article summarizes three other studies on infective endocarditis, coronary artery bypass grafting, and myocarditis, providing valuable insights into different aspects of cardiovascular health and treatment.

Background and Aims Uncertainty exists over whether multiple arterial grafting has a sex-related association with survival after coronary artery bypass grafting. This study aims to compare the long-term survival of using multiple arterial grafting vs. single arterial grafting in women and men undergoing coronary artery bypass grafting. Methods The retrospective study used the Australian and New Zealand Society of Cardiothoracic Surgical Database with linkage to the National Death Index. Patients from 2001 to 2020 were identified. Sex-stratified, inverse probability weighted Cox proportional hazard model was used to facilitate survival comparisons. The primary outcome was all-cause mortality. Results A total number of 54 275 adult patients receiving at least two grafts in primary isolated bypass operations were analysed. The entire study cohort consisted of 10 693 (19.7%) female patients and 29 711 (54.7%) multiple arterial grafting procedures. At a median (interquartile range) postoperative follow-up of 4.9 (2.3–8.4) years, mortality was significantly lower in male patients undergoing multiarterial than single arterial procedures (adjusted hazard ratio 0.82; 95% confidence interval 0.77–0.87; P <.001). The survival benefit was also significant for females (adjusted hazard ratio 0.83; 95% confidence interval 0.76–0.91; P <.001) at a median (interquartile range) follow-up of 5.2 (2.4–8.7) years. The interaction model from Cox regression suggested insignificant subgroup effect from sex (P =.08) on the observed survival advantage. The survival benefits associated with multiple arterial grafting were consistent across all sex-stratified subgroups except for female patients with left main coronary disease. Conclusions Compared to single arterial grafting, multiple arterial revascularization is associated with improved long-term survival for women as well as men. [ABSTRACT FROM AUTHOR]

Objective: The impact of nitric oxide (NO) administered via cardiopulmonary bypass (CPB) on pediatric heart surgery remains controversial. The objective of this study is to conduct a comprehensive systematic review and meta-analysis to examine the impact of NO administered via CPB on pediatric heart surgery. Methods: This study searched 7 electronic databases to identify Randomized Controlled Trials (RCTs) on the impact of NO administration during CPB on postoperative outcomes in pediatric heart surgery. The searched databases included Embase, Medline (though PubMed), Cochrane Library, Web of Science, Wan Fang database, China National Knowledge Infrastructure (CNKI), and ClinicalTrials.gov from their inception to November 2, 2022. The included RCTs compared NO administration during CPB with standard CPB procedures or placebo gas treatment in pediatric heart surgery. fixed-effects models and/or random-effects models were used to estimate the effect size with 95% confidence interval (CI). Heterogeneity among studies was indicated by p-values and I2. All analyses were performed using Review Manager software (version 5.4) in this study. Results: A total of 6 RCTs including 1,739 children were identified in this study. The primary outcome was duration of postoperative mechanical ventilation, with the length of hospital and intensive care unit (ICU) stay as the second outcomes. Through a pooled analysis, we found that exogenous NO administered via CPB for pediatric heart surgery could not shorten the duration of postoperative mechanical ventilation when compared with the control group (standardized mean difference (SMD) -0.07, CI [–0.16, 0.02], I2 = 45%, P = 0.15). Additionally, there were also no difference between the two groups in terms of length of hospital stay (mean difference (MD) -0.29, CI [–1.03, 0.46], I2 = 32%, P = 0.45) and length of ICU stay (MD -0.22, CI [–0.49 to 0.05], I2 = 72%, P = 0.10). Conclusions: This meta-analysis showed that exogenous NO administration via CBP had no benefits on the duration of mechanical ventilation, the length of postoperative hospital, and ICU stay after pediatric heart surgery.

Background: Aprotinin, a serine protease inhibitor, has been used variably in cardiac surgery amidst ongoing debates about its safety following several previous studies. This study assesses the outcomes of aprotinin in high-risk isolated Coronary Artery Bypass Graft (iCABG) patients. Methods: The study retrospectively analysed a cohort of 1026 iCABG patients, including 51 patients who underwent aprotinin treatment. Logistic regression powered score matching was employed to compare aprotinin patients with a control group, in a propensity-matched cohort of 96 patients. The primary outcome measured was in-hospital death, with secondary outcomes including renal dysfunction, stroke, myocardial infarction, re-exploration for bleeding or tamponade, and postoperative stay durations. Results: The aprotinin cohort had high-risk preoperative patients with significantly higher EUROSCORE II values, 7.5 (± 4.2), compared to 3.9 (± 2.5) in control group. However, aprotinin group showed no statistically significant increase (p-value: 0.44) in hospital mortality with OR 2.5 [95% CI 0.51, 12.3]. Major secondary outcome rates of renal replacement therapy and postoperative stroke compared to the control group were also statistically insignificant between the two groups. Conclusion: This study suggests that aprotinin may be safely used in a select group of high-risk iCABG patients. The reintroduction of aprotinin under specific conditions reflects its potential benefits in managing bleeding in high-risk surgeries, but also underscores the complexity of its risk-benefit profile in such critical care settings. Nonetheless, it highlights the importance of carefully selecting patients and conducting additional research, including larger and more controlled studies to fully comprehend the potential risks and benefits of aprotinin.

The sudden exposure of venous endothelial cells (vECs) to arterial fluid shear stress (FSS) is thought to be a major contributor to coronary artery bypass vein graft failure (VGF). However, the effects of arterial FSS on the vEC secretome are poorly characterised. We propose that analysis of the vEC secretome may reveal potential therapeutic approaches to suppress VGF. Human umbilical vein endothelial cells (HUVECs) pre-conditioned to venous FSS (18 h; 1.5 dynes/cm2) were exposed to venous or arterial FSS (15 dynes/cm2) for 24 h. Tandem Mass Tagging proteomic analysis of the vEC secretome identified significantly increased fibroleukin (FGL2) in conditioned media from HUVECs exposed to arterial FSS. This increase was validated by Western blotting. Application of the NFκB inhibitor BAY 11-7085 (1 µM) following pre-conditioning reduced FGL2 release from vECs exposed to arterial FSS. Exposure of vECs to arterial FSS increased apoptosis, measured by active cleaved caspase-3 (CC3) immunocytochemistry, which was likewise elevated in HUVECs treated with recombinant FGL2 (20 ng/mL) for 24 h under static conditions. To determine the mechanism of FGL2-induced apoptosis, HUVECs were pre-treated with a blocking antibody to FcγRIIB, a receptor FGL2 is proposed to interact with, which reduced CC3 levels. In conclusion, our findings indicate that the exposure of vECs to arterial FSS results in increased release of FGL2 via NFκB signalling, which promotes endothelial apoptosis via FcγRIIB signalling. Therefore, the inhibition of FGL2/FcγRIIB signalling may provide a novel approach to reduce arterial FSS-induced vEC apoptosis in vein grafts and suppress VGF. [ABSTRACT FROM AUTHOR]

MITRAL valve insufficiency , *MITRAL valve surgery , *CORONARY artery bypass , *VENTRICULAR fibrillation , *TYPE 1 diabetes - Abstract
Background: Minimally invasive mitral valve surgery (MIMVS) is a treatment for severe mitral valve pathologies. In redo cases, especially after coronary artery bypass grafting (CABG) surgery with patent mammary bypass grafts, establishing aortic clamping followed by antegrade cardioplegia application might be challenging. Here, we present the outcome of hypothermic ventricular fibrillation as an alternative to conventional cardioprotection. Methods: Patients who underwent MIMVS either received hypothermic ventricular fibrillation (study group, n = 48) or antegrade cardioprotection (control group, n = 840) and were observed for 30 postoperative days. Data were retrospectively analyzed and collected from January 2011 until December 2022. Results: Patients in the study group had a higher preoperative prevalence of renal insufficiency (p = 0.001), extracardiac arteriopathy (p = 0.001), insulin-dependent diabetes mellitus (p = 0.001) and chronic lung disease (p = 0.036). Furthermore, they had a longer surgery time and a lower repair rate (p < 0.001). No difference, however, was seen in postoperative incidences of stroke (p = 0.26), myocardial infarction (p = 1) and mitral valve re-operation (p = 1) as well as 30-day mortality (p = 0.1) and postoperative mitral valve insufficiency or stenosis. Conclusions: The patients who underwent redo MIMVS with hypothermic ventricular fibrillation did not have worse outcomes or more serious adverse events compared to the patients who received routine conventional cardioprotection. Therefore, the use of hypothermic ventricular fibrillation appears to be a promising cardioprotective technique in this challenging patient population requiring redo MIMVS. [ABSTRACT FROM AUTHOR]

The influence of gender on both early and long-term outcomes of coronary artery bypass grafting (CABG) is not clearly defined. Objectives: This study aimed to assess the impact of gender on early and long-term mortality after CABG using data from the KROK Registry. Methods: All 133,973 adult patients who underwent CABG in Poland between 1 January 2009 and 31 December 2019 were included in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry). The study enrolled 90,541 patients: 68,401 men (75.55%) and 22,140 women (24.45%) who met the inclusion criteria. Then, 30-day mortality, 1-year mortality, and long-term mortality rates were compared. Results: Advanced age, higher Canadian Cardiovascular Society (CCS) and New York Heart Association (NYHA) grade, diabetes, hypercholesterolemia, arterial hypertension, body mass index BMI > 35 kg/m2, and renal failure, before the propensity matching, were more frequently observed in women. Women more frequently underwent urgent surgery, including single and double graft surgery, and off-pump CABG (OPCAB) (p < 0.001). In propensity-matched groups, early mortality (30 days) was significantly higher in women (3.4% versus 2.8%, p < 0.001). The annual mortality remained higher in this group (6.6% versus 6.0%, p = 0.025). However, long-term mortality differed significantly between the groups and was higher in the male group (33.0% men versus 28.8% women, p < 0.001). Conclusions: There are no apparent differences in long-term mortality between the two sexes in the entire population. In propensity-matched patients, early mortality was lower for men, but the long-term survival was found to be better in women. [ABSTRACT FROM AUTHOR]

Background: Extra-anatomic ascending-to-descending aortic bypass grafts have historically been utilized as a safe and effective solution for repairs of complex coarctation of the aorta. However, reports on reoperation in these patients remain rare. We present a case of an aortic valve replacement and coronary artery bypass grafting in a patient with an extra-anatomic ascending-to-descending aortic bypass graft. Case presentation: The patient is a 59-year-old male with a complex aortic history, including repair of aortic coarctation with an ascending-to-descending aortic bypass graft 13 years prior, was admitted to the hospital for shortness of breath and chest pain that had developed over the past year. On further workup, he was found to have severe bileaflet aortic valve stenosis, non-ST elevation myocardial infarction, and moderate coronary artery disease. He underwent surgical aortic valve replacement and coronary artery bypass grafting. Given his unique anatomy, cardiopulmonary bypass approach involved separate cannulation of the right axillary and left common femoral arteries with cross-clamp of both the aorta and the extra-anatomic graft. Using this approach, the redo operation was successfully performed. Conclusions: Reports on reoperation after ascending-to-descending aortic bypass grafting are rare. We describe our approach to cardiopulmonary bypass and reoperation in a patient with an extra-anatomic ascending-to-descending aortic bypass graft. [ABSTRACT FROM AUTHOR]

Objectives Methods Results Conclusions Post‐cardiotomy extracorporeal life support (ECLS) cannulation might occur in a general post‐operative ward due to emergent conditions. Its characteristics have been poorly reported and investigated This study investigates the characteristics and outcomes of adult patients receiving ECLS cannulation in a general post‐operative cardiac ward.The Post‐cardiotomy Extracorporeal Life Support (PELS) is a retrospective (2000–2020), multicenter (34 centers), observational study including adult patients who required ECLS for post‐cardiotomy shock. This PELS sub‐analysis analyzed patients´ characteristics, in‐hospital outcomes, and long‐term survival in patients cannulated for veno‐arterial ECLS in the general ward, and further compared in‐hospital survivors and non‐survivors.The PELS study included 2058 patients of whom 39 (1.9%) were cannulated in the general ward. Most patients underwent isolated coronary bypass grafting (CABG, n = 15, 38.5%) or isolated non‐CABG operations (n = 20, 51.3%). The main indications to initiate ECLS included cardiac arrest (n = 17, 44.7%) and cardiogenic shock (n = 14, 35.9%). ECLS cannulation occurred after a median time of 4 (2–7) days post‐operatively. Most patients' courses were complicated by acute kidney injury (n = 23, 59%), arrhythmias (n = 19, 48.7%), and postoperative bleeding (n = 20, 51.3%). In‐hospital mortality was 84.6% (n = 33) with persistent heart failure (n = 11, 28.2%) as the most common cause of death. No peculiar differences were observed between in‐hospital survivors and nonsurvivors.This study demonstrates that ECLS cannulation due to post‐cardiotomy emergent adverse events in the general ward is rare, mainly occurring in preoperative low‐risk patients and after a postoperative cardiac arrest. High complication rates and low in‐hospital survival require further investigations to identify patients at risk for such a complication, optimize resources, enhance intervention, and improve outcomes.

This article discusses the management of non-ST-elevation acute coronary syndrome (NSTE-ACS) in patients with previous coronary artery bypass graft surgery (CABG). While a routine invasive approach with coronary angiography is recommended for NSTE-ACS patients, it is unclear if this approach is beneficial for those with prior CABG. A meta-analysis of 11 randomized clinical trials found no significant difference in mortality, cardiac mortality, myocardial infarction, or cardiac hospitalizations between a routine invasive and selective invasive approach in this high-risk population. However, further research is needed to determine the best management strategy for NSTE-ACS patients with prior CABG. [Extracted from the article]
