Atrial Septostomy for Left Ventricular Unloading During Extracorporeal Membrane Oxygenation for Cardiogenic Shock: Animal Model. JACC Cardiovasc Interv 2021; 14:2698-2707. [PMID: 34949394 DOI: 10.1016/j.jcin.2021.09.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 08/11/2021] [Accepted: 09/14/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES The aim of this study was to quantify and understand the unloading effect of percutaneous balloon atrial septostomy (BAS) in acute cardiogenic shock (CS) treated with venoarterial (VA) extracorporeal membranous oxygenation (ECMO). BACKGROUND In CS treated with VA ECMO, increased left ventricular (LV) afterload is observed that commonly interferes with myocardial recovery or even promotes further LV deterioration. Several techniques for LV unloading exist, but the optimal strategy and the actual extent of such procedures have not been fully disclosed. METHODS In a porcine model (n = 11; weight 56 kg [53-58 kg]), CS was induced by coronary artery balloon occlusion (57 minutes [53-64 minutes]). Then, a step-up VA ECMO protocol (40-80 mL/kg/min) was run before and after percutaneous BAS was performed. LV pressure-volume loops and multiple hemoglobin saturation data were evaluated. The Wilcoxon rank sum test was used to assess individual variable differences. RESULTS Immediately after BAS while on VA ECMO support, LV work decreased significantly: pressure-volume area, end-diastolic pressure, and stroke volume to ∼78% and end-systolic pressure to ∼86%, while superior vena cava and tissue oximetry did not change. During elevating VA ECMO support (40-80 mL/kg/min) with BAS vs without BAS, we observed 1) significantly less mechanical work increase (122% vs 172%); 2) no end-diastolic volume increase (100% vs 111%); and 3) a considerable increase in end-systolic pressure (134% vs 144%). CONCLUSIONS In acute CS supported by VA ECMO, atrial septostomy is an effective LV unloading tool. LV pressure is a key component of LV work load, so whenever LV work reduction is a priority, arterial pressure should carefully be titrated low while maintaining organ perfusion.

Abstract
OBJECTIVES Papillary muscle rupture (PMR) is a rare but potentially fatal complication of acute myocardial infarction. The aim of this study was to analyse the patient characteristics and early outcomes of the surgical management of post-infarction PMR from an international multicentre registry. METHODS Patients underwent surgery for post-infarction PMR between 2001 through 2019 were retrieved from database of the CAUTION study. The primary end point was in-hospital mortality. RESULTS A total of 214 patients were included with a mean age of 66.9 (standard deviation: 10.5) years. The posteromedial papillary muscle was the most frequent rupture location (71.9%); the rupture was complete in 67.3% of patients. Mitral valve replacement was performed in 82.7% of cases. One hundred twenty-two patients (57%) had concomitant coronary artery bypass grafting. In-hospital mortality was 24.8%. Temporal trends revealed no apparent improvement in in-hospital mortality during the study period. Multivariable analysis showed that preoperative chronic kidney disfunction [odds ratio (OR): 2.62, 95% confidence interval (CI): 1.07-6.45, P = 0.036], cardiac arrest (OR: 3.99, 95% CI: 1.02-15.61, P = 0.046) and cardiopulmonary bypass duration (OR: 1.01, 95% CI: 1.00-1.02, P = 0.04) were independently associated with an increased risk of in-hospital death, whereas concomitant coronary artery bypass grafting was identified as an independent predictor of early survival (OR: 0.38, 95% CI: 0.16-0.92, P = 0.031). CONCLUSIONS Surgical treatment for post-infarction PMR carries a high in-hospital mortality rate, which did not improve during the study period. Because concomitant coronary artery bypass grafting confers a survival benefit, this additional procedure should be performed, whenever possible, in an attempt to improve the outcome.

Abstract
Abstract
Background
Aortic valve (AV) stenosis can be treated either by surgical AV replacement (SAVR) or since 2002 by transcatheter aortic valve implantation (TAVI). Due to lower invasiveness, TAVI is a preferred approach in high- and prohibitive risk surgical candidates, yet outcome data is conflicting when lower risk patients are considered and in particular at long-term.
Purpose
Our study evaluates long-term survival in elective low-risk patients after AV replacement with severe AV stenosis.
Methods
We conducted a registry data analyses of patients scheduled for elective isolated AV with AV stenosis between 2015 and 2019 and underwent TAVI or SAVR. Urgent, emergent and salvage procedures were excluded. In TAVI group only transfemoral access was considered. Propensity score matching to determine SAVR controls for TAVI group in 1:3 ratio with caliper 0.2 of standardized deviation (figure 1).
Results
Study group included 2393 elective AVR patients 1765 was in SAVR group and 628 in TAVI group. Median follow-up was 2.72 years ([IQR: 1.32–4.08], max 6.0). Propensity matching with replacement returned 329 TAVI cases and 593 SAVR controls with median age 76 (Interquartile range [IQR:71–73]) and EuroScore II 1.81 [IQR:1.36–2.53]). 30-day mortality was 11/329 (3.32%) vs 18/593 (3.03%) in the TAVI vs SAVR respectively (RR 1.10 [0.52–2.37]; p=0.801). At two years, there was no difference between SAVR and TAVI in terms of mortality (HR 1.23 [0.83–1.83] P=0.309). At 6 years, overall survival analysis favored SAVR which was associated with 30% lower mortality (HR 0.70 [0.496–0.997]; p=0.048, see figure 2).
Conclusions
TAVI as compared to SAVR is equally safe in elective low-risk patients up to 2 years post-op. After that time survival is better in surgically managed patients. Extended observations from randomized trials in low-risk patients are warranted to draw definite conclusions regarding long-term safety of TAVI in this population.

Abstract
IMPORTANCE Ventricular septal rupture (VSR) is a rare but life-threatening mechanical complication of acute myocardial infarction associated with high mortality despite prompt treatment. Surgery represents the standard of care; however, only small single-center series or national registries are usually available in literature, whereas international multicenter investigations have been poorly carried out, therefore limiting the evidence on this topic. OBJECTIVES To assess the clinical characteristics and early outcomes for patients who received surgery for postinfarction VSR and to identify factors independently associated with mortality. DESIGN, SETTING, AND PARTICIPANTS The Mechanical Complications of Acute Myocardial Infarction: an International Multicenter Cohort (CAUTION) Study is a retrospective multicenter international cohort study that includes patients who were treated surgically for mechanical complications of acute myocardial infarction. The study was conducted from January 2001 to December 2019 at 26 different centers worldwide among 475 consecutive patients who underwent surgery for postinfarction VSR. EXPOSURES Surgical treatment of postinfarction VSR, independent of the technique, alone or combined with other procedures (eg, coronary artery bypass grafting). MAIN OUTCOMES AND MEASURES The primary outcome was early mortality; secondary outcomes were postoperative complications. RESULTS Of the 475 patients included in the study, 290 (61.1%) were men, with a mean (SD) age of 68.5 (10.1) years. Cardiogenic shock was present in 213 patients (44.8%). Emergent or salvage surgery was performed in 212 cases (44.6%). The early mortality rate was 40.4% (192 patients), and it did not improve during the nearly 20 years considered for the study (median [IQR] yearly mortality, 41.7% [32.6%-50.0%]). Low cardiac output syndrome and multiorgan failure were the most common causes of death (low cardiac output syndrome, 70 [36.5%]; multiorgan failure, 53 [27.6%]). Recurrent VSR occurred in 59 participants (12.4%) but was not associated with mortality. Cardiogenic shock (survived: 95 [33.6%]; died, 118 [61.5%]; P < .001) and early surgery (time to surgery ≥7 days, survived: 105 [57.4%]; died, 47 [35.1%]; P < .001) were associated with lower survival. At multivariate analysis, older age (odds ratio [OR], 1.05; 95% CI, 1.02-1.08; P = .001), preoperative cardiac arrest (OR, 2.71; 95% CI, 1.18-6.27; P = .02) and percutaneous revascularization (OR, 1.63; 95% CI, 1.003-2.65; P = .048), and postoperative need for intra-aortic balloon pump (OR, 2.98; 95% CI, 1.46-6.09; P = .003) and extracorporeal membrane oxygenation (OR, 3.19; 95% CI, 1.30-7.38; P = .01) were independently associated with mortality. CONCLUSIONS AND RELEVANCE In this study, surgical repair of postinfarction VSR was associated with a high risk of early mortality; this risk has remained unchanged during the last 2 decades. Delayed surgery seemed associated with better survival. Age, preoperative cardiac arrest and percutaneous revascularization, and postoperative need for intra-aortic balloon pump and extracorporeal membrane oxygenation were independently associated with early mortality. Further prospective studies addressing preoperative and perioperative patient management are warranted to hopefully improve the currently suboptimal outcome.

Abstract
Background The NAUTILUS study aimed to evaluate the safety and performance of the Allegra bioprosthesis in high-risk recipients undergoing transcatheter aortic valve implantation and previously reported 30-day outcomes. In the current investigation 1-year results of the trial are presented. Methods Twenty-seven recipients with severe, symptomatic aortic valve stenosis at high surgical risk, who underwent treatment using the next-generation self-expanding Allegra via transfemoral approach were prospectively enrolled. Clinical endpoints assessed were: mortality, stroke, permanent pacemaker implantation, New York Heart Association class and re-hospitalizations. Prosthetic valve performance evaluation comprised of: mean gradient, effective orifice area and paravalvular leak. Results Patients were elderly (82.8 ± 4.2 years) and predominantly female (n = 19, 70.4%). All of them were deemed to be at high surgical risk with a mean logistic EuroSCORE of 12.5 ± 6.7. The bioprosthesis was successfully implanted in 92.6% of the cases (n = 25). At 1-year, all-cause mortality was 12.0% (n = 3) and stroke was 4.0% (n = 1). Three (12%) of patients developed complete atrioventricular block and received permanent pacemakers. 84% of patients were in New York Heart Association class II or lower. Need for subsequent hospitalization arose in 48% patients. The echocardiographic assessment confirmed an acceptable hemodynamic profile of the Allegra with low mean transprosthetic gradient (9.5 ± 3.4 mmHg), absence of severe paravalvular leak and a 20%-presence of moderate paravalvular leak. Conclusions The current follow-up observation study shows that the Allegra was associated with a satisfactory safety profile and hemodynamic performance at 1-year after implantation.

Abstract
OBJECTIVES There is no consensus regarding the use of biological or mechanical prostheses in patients 50-69 years of age. Previous studies have reported a survival advantage with mechanical valves. Our goal was to compare the long-term survival of patients in the intermediate age groups of 50-59 and 60-69 years receiving mechanical or biological aortic valve prostheses. METHODS We conducted a retrospective analysis of patients in the age groups 50-59 years (n = 329) and 60-69 years (n = 648) who had a first-time isolated aortic valve replacement between 2000 and 2019. Kaplan-Meier and competing risk analyses were performed to compare survival, incidence of aortic valve reoperation, haemorrhagic complications and thromboembolic events for mechanical versus biological prostheses. RESULTS Patients aged 50-59 years with a biological prosthesis had a higher probability of aortic valve reintervention (26.3%, biological vs 2.6% mechanical; P < 0.001 at 15 years). The incidence of haemorrhagic complications or thromboembolic events was similar in the 2 groups. Patients aged 60-69 years with a mechanical prosthesis had a higher risk of haemorrhagic complications (6.9%, biological vs 16.2%, mechanical; P = 0.001 at 15 years). Biological prostheses had a higher overall probability of reintervention for valve dysfunction (20.9%, biological vs 4.8%, mechanical; P = 0.024). In both age groups, there was no difference in long-term survival between patients receiving a biological or a mechanical prosthesis. CONCLUSIONS There was no difference in long-term survival between mechanical and biological prostheses for both age groups. Mechanical prostheses had a higher risk of bleeding in the 60-69-year group whereas biological valves had higher overall reintervention probability without an impact on long-term survival. It may be safe to use biological valves based on lifestyle choices for patients in the 50-69-year age group.

Abstract
OBJECTIVES Refractory postcardiotomy cardiogenic shock complicating cardiac surgery yields nearly 100% mortality when untreated. Use of venoarterial extracorporeal membrane oxygenation for postcardiotomy cardiogenic shock has increased worldwide recently. The aim of the current analysis was to outline the trends in use, changing patient profiles, and in-hospital outcomes including complications in patients undergoing venoarterial extracorporeal membrane oxygenation for postcardiotomy cardiogenic shock. DESIGN Analysis of extracorporeal life support organization registry from January 2010 to December 2018. SETTING Multicenter worldwide registry. PATIENTS Seven-thousand one-hundred eighty-five patients supported with venoarterial extracorporeal membrane oxygenation for postcardiotomy cardiogenic shock. INTERVENTIONS Venoarterial extracorporeal membrane oxygenation. MEASUREMENTS AND MAIN RESULTS Hospital death, weaning from extracorporeal membrane oxygenation, hospital complications. Mortality predictors were assessed by multivariable logistic regression. Propensity score matching was performed for comparison of peripheral and central cannulation for extracorporeal membrane oxygenation. A significant trend toward more extracorporeal membrane oxygenation use in recent years (coefficient, 0.009; p < 0.001) was found. Mean age was 56.3 ± 14.9 years and significantly increased over time (coefficient, 0.513; p < 0.001). Most commonly, venoarterial extracorporeal membrane oxygenation was instituted after coronary artery bypass surgery (26.8%) and valvular surgery (25.6%), followed by heart transplantation (20.7%). Overall, successful extracorporeal membrane oxygenation weaning was possible in 4,520 cases (56.4%), and survival to hospital discharge was achieved in 41.7% of cases. In-hospital mortality rates remained constant over time (coefficient, -8.775; p = 0.682), whereas complication rates were significantly reduced (coefficient, -0.009; p = 0.003). Higher mortality was observed after coronary artery bypass surgery (65.4%), combined coronary artery bypass surgery with valve (68.4%), and aortic (69.6%) procedures than other indications. Lower mortality rates were observed in heart transplantation recipients (46.0%). Age (p < 0.001), central cannulation (p < 0.001), and occurrence of complications while on extracorporeal membrane oxygenation were independently associated with poorer prognosis. CONCLUSIONS The analysis confirmed increased use of venoarterial extracorporeal membrane oxygenation for postcardiotomy cardiogenic shock. Mortality rates remained relatively constant over time despite a decrease in complications, in the setting of supporting older patients.

Abstract
In SARS-CoV-2 patients with severe acute respiratory distress syndrome (ARDS), Veno-Venous Extracorporeal Membrane Oxygenation (V-V ECMO) was shown to provide valuable treatment with reasonable survival in large multi-centre investigations. However, in some patients, conversion to modified ECMO support forms may be needed. In this single-centre retrospective registry, all consecutive patients receiving V-V ECMO between 1 March 2020 to 1 May 2021 were included and analysed. The patient cohort was divided into two groups: those who remained on V-V ECMO and those who required conversion to other modalities. Seventy-eight patients were included, with fourteen cases (18%) requiring conversions to veno-arterial (V-A) or hybrid ECMO. The reasons for the ECMO mode configuration change were inadequate drainage (35.7%), inadequate perfusion (14.3%), myocardial infarction (7.1%), hypovolemic shock (14.3%), cardiogenic shock (14.3%) and septic shock (7.1%). In multivariable analysis, the use of dobutamine (p = 0.007) and a shorter ICU duration (p = 0.047) predicted the conversion. The 30-day mortality was higher in converted patients (log-rank p = 0.029). Overall, only 19 patients (24.4%) survived to discharge or lung transplantation. Adverse events were more common after conversion and included renal, cardiovascular and ECMO-circuit complications. Conversion itself was not associated with mortality in the multivariable analysis. In conclusion, as many as 18% of patients undergoing V-V ECMO for COVID-19 ARDS may require conversion to advanced ECMO support.

Abstract
INTRODUCTION Phaeochromocytoma is a catecholamine-secreting tumour associated with clinical presentation ranging from paroxysmal hypertension to intractable cardiogenic shock. Extracorporeal life support, in veno-arterial mode, application in refractory acute heart dysfunction is sharply increasing worldwide. However, its clinical utility in phaeochromocytoma-induced cardiogenic shock remains still unclear. METHODS A systematic review of published reports was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Statement. Searches were accomplished on PubMed, Embase and Google Scholar to identify articles describing the use of extracorporeal life support in the setting of phaeochromocytoma-induced cardiogenic shock (PROSPERO: CRD42019125225). RESULTS Thirty-five reports, including 62 patients supported with extracorporeal life support because of intractable phaeochromocytoma crisis, were included for the analysis. Almost all the subjects underwent peripheral cannulation for extracorporeal life support. The median duration of the mechanical circulatory support was 5 days, and most of the patients recovered normal myocardial function (left ventricular ejection fraction ⩾50%). In-hospital survival was 87%. Phaeochromocytoma was removed surgically during extracorporeal life support in 10 patients (16%), while in the remaining after haemodynamic stabilization and weaning from the mechanical support. CONCLUSION Successful management of phaeochromocytoma-induced cardiogenic shock depends on prompt recognition and immediate treatment of shock. In this scenario, extracorporeal life support may play a significant role allowing cardiac and end-organ recovery and giving time for accurate diagnosis and specific treatment.

Abstract
BACKGROUND Historically, impaired glucose metabolism has been associated with early and late complicated clinical outcomes after cardiac surgery; however, such a condition is not specific to subjects with diabetes mellitus and involves a larger patient population. METHODS Databases were screened (January 2000 to December 2020) to identify eligible articles; studies that evaluated the association between preoperative metabolic status, as assessed by glycosylated hemoglobin levels and clinical outcomes, were considered. The studies were stratified in thresholds by baseline glycosylated hemoglobin level (lower vs higher). RESULTS Thirty studies, involving 34,650 patients, were included in the review. In a meta-analysis stratified by glycosylated hemoglobin levels, early mortality was numerically reduced in each threshold comparison and yielded the highest reductions when less than 5.5% versus greater than 5.5% glycosylated hemoglobin levels were compared (risk ratio, 0.39; 95% confidence interval, 0.18-0.84; P = .02). Comparing higher glycosylated hemoglobin threshold values yielded comparable results. Late mortality was reduced with lower levels of glycosylated hemoglobin. Low preoperative glycosylated hemoglobin was associated with the lowest risk of sternal wound infections (risk ratio, 0.50; 95% confidence interval, 0.32-0.80; P = .003 and risk ratio, 0.53; 95% confidence interval, 0.39-0.70; P < .0001) for comparisons of less than 7.5% versus greater than 7.5% and less than 7.0% versus greater than 7.0% glycosylated hemoglobin thresholds, respectively. Additionally, levels of glycosylated hemoglobin lower than 7% were associated with reduced hospital stay, lower risk of stroke/transient ischemic attack (risk ratio 0.53; 95% confidence interval, 0.39-0.70; P < .0001), and acute kidney injury (risk ratio, 0.65; 95% confidence interval, 0.54-0.79; P < .0001). CONCLUSIONS Lower levels of glycosylated hemoglobin in patients undergoing cardiac surgery are associated with a lower risk of early and late mortality, as well as in the incidence of postoperative acute kidney injury, neurologic complications, and wound infection, compared with higher levels.

[PMID: 34075615 PMCID: PMC8453579 DOI: 10.1111/jocs.15701] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 04/09/2021] [Accepted: 05/02/2021] [Indexed: 11/29/2022]
Abstract
Background Left ventricular free‐wall rupture (LVFWR) is one of the most lethal complications after acute myocardial infarction (AMI). The optimal therapeutic strategy is controversial. The current meta‐analysis sought to examine the outcome of patients surgically treated for post‐AMI LVFWR. Methods A comprehensive literature review was performed to identify articles reporting outcomes of subjects who underwent LVFWR surgical repair. The primary endpoint was operative mortality. A meta‐analysis was performed to assess the associations of predefined variables of interest and clinical prognosis. Results Of the 3132 retrieved articles, 11 nonrandomized studies, enrolling a total of 363 patients, fulfilled the inclusion criteria and were included in this analysis. The mean age of patients was 68 years. The operative mortality rate was 32% (n = 115). Meta‐analysis revealed reduced operative risk in patients with oozing type rupture, as compared to blowout type (risk ratios [RR]: 0.47; 95% confidence interval [CI]: 0.33–0.67; p < .0001); RR was also significantly reduced in subjects in whom LVFWR was treated with sutureless technique, as compared to those undergoing sutured repair (RR: 0.59; 95% CI: 0.41–0.83; p = .002). Increased risk of operative mortality was demonstrated in patients who required postoperative extracorporeal membrane oxygenation (ECMO) support (RR: 2.39; 95% CI: 1.59–3.60; p < .0001). Conclusions Surgical treatment of postinfarction LVFWR has a high operative mortality rate. Blowout rupture, sutured repair and postoperative ECMO support are factors associated with increased risk of operative mortality.

Abstract
Background Data regarding the clinical outcomes of covered stents (CSs) used to seal coronary artery perforations (CAPs) in the all-comer population are scarce. The aim of the CRACK Registry was to evaluate the procedural, 30-days and 1-year outcomes after CAP treated by CS implantation. Methods This multicenter all-comer registry included data of consecutive patients with CAP treated by CS implantation. The primary endpoint was the composite of major adverse cardiac events (MACEs), defined as cardiac death, target lesion revascularization (TLR), and myocardial infarction (MI). Results The registry included 119 patients (mean age: 68.9 ± 9.7 years, 55.5% men). Acute coronary syndrome, including: unstable angina 21 (17.6%), NSTEMI 26 (21.8%), and STEMI 26 (21.8%), was the presenting diagnosis in 61.3%, and chronic coronary syndromes in 38.7% of patients. The most common lesion type, according to ACC/AHA classification, was type C lesion in 47 (39.5%) of cases. A total of 52 patients (43.7%) had type 3 Ellis classification, 28 patients (23.5%) had type 2 followed by 39 patients (32.8%) with type 1 perforation. Complex PCI was performed in 73 (61.3%) of patients. Periprocedural death occurred in eight patients (6.7%), of which two patients had emergency cardiac surgery. Those patients were excluded from the one-year analysis. Successful sealing of the perforation was achieved in 99 (83.2%) patients. During the follow-up, 26 (26.2%) patients experienced MACE [7 (7.1%) cardiac deaths, 13 (13.1%) TLR, 11 (11.0%) MIs]. Stent thrombosis (ST) occurred in 6 (6.1%) patients [4(4.0%) acute ST, 1(1.0%) subacute ST and 1(1.0%) late ST]. Conclusions The use of covered stents is an effective treatment of CAP. The procedural and 1-year outcomes of CAP treated by CS implantation showed that such patients should remain under follow-up due to relatively high risk of MACE.

Systematic review and meta-analysis of the clinical effectiveness of point-of-care testing for anticoagulation management during ECMO. J Clin Anesth 2021; 73:110330. [PMID: 33962338 DOI: 10.1016/j.jclinane.2021.110330] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 04/17/2021] [Accepted: 04/20/2021] [Indexed: 12/26/2022]
Abstract
STUDY OBJECTIVE Viscoelastic point-of-care (POC) tests are commonly used to provide prompt diagnosis of coagulopathy and allow targeted treatments in bleeding patients on ECMO. We evaluated the clinical effectiveness of point-of-care (POC) testing for anticoagulation management in patients on extracorporeal membrane oxygenation (ECMO). DESIGN Systematic review and meta-analysis. Eligible studies evaluating the use of thromboelastography- or thromboelastometry-guided algorithms, anti-factor Xa and platelet function testing were selected after screening the literature from July 1975 to January 2020. SETTING Patients on ECMO support. PATIENTS Anticoagulation management on ECMO patients. INTERVENTIONS Rotational thromboelastometry, thromboelastography, alone or combined with platelet function testing. Trials monitoring the anticoagulation effects during ECMO using an anti-factor Xa assay were included in the systematic review. MEASUREMENTS The primary outcomes were bleeding events, surgical revisions, thrombosis events and ECMO circuit change/failure. Secondary outcomes were blood-product transfusions, cerebrovascular accidents, mortality on ECMO, ECMO duration, intensive care unit and hospital discharge rates, and in-hospital mortality. MAIN RESULTS Thirty-one trials enrolling 1684 participants were included in the systematic review. Four trials enrolling 547 subjects were included in the meta-analysis. The use of a POC testing device resulted in improved detection of surgical bleeding (RR: 0.68, 95% CI 0.49 to 0.94, I2 = 0%; χ2 test for heterogeneity, P = 0.02). The use of POC-guided algorithms did not affect bleeding (RR:0.78, 95% CI 0.58 to 1.04, I2 = 47%; χ2 test for heterogeneity, P = 0.09), thrombosis events (RR:1.35, 95% CI 0.86 to 2.12, I2 = 37%; χ2 test for heterogeneity, P = 0.19), or ECMO circuit/change (RR:0.90, 95% CI 0.48 to 1.71, I2 = 28%; χ2 test for heterogeneity, P = 0.75). CONCLUSION Routine use of POC tests did not improve the main clinical outcomes beyond suggesting a diagnosis of surgical bleeding in ECMO patients.

Abstract
Extracorporeal life support (ECLS) is indicated in refractory acute respiratory or cardiac failure. According to the need for anticoagulation, bleeding conditions (e.g., in trauma, pulmonary bleeding) have been considered a contraindication for the use of ECLS. However, there is increasing evidence for improved outcomes after ECLS support in hemorrhagic patients based on the benefits of hemodynamic support outweighing the increased risk of bleeding. We conducted a systematic literature search according to the PRISMA guidelines and reviewed publications describing ECLS support in hemorrhagic conditions. Seventy-four case reports, four case series, seven retrospective database observational studies, and one preliminary result of an ongoing study were reviewed. In total, 181 patients were identified in total of 86 manuscripts. The reports included patients suffering from bleeding caused by pulmonary hemorrhage (n = 53), trauma (n = 96), postpulmonary endarterectomy (n = 13), tracheal bleeding (n = 1), postpartum or cesarean delivery (n = 11), and intracranial hemorrhage (n = 7). Lower targeted titration of heparin infusion, heparin-free ECLS until coagulation is normalized, clamping of the endotracheal tube, and other ad hoc possibilities represent potential beneficial maneuvers in such conditions. Once the patient is cannulated and circulation restored, bleeding control surgery is performed for stabilization if indicated. The use of ECLS for temporary circulatory or respiratory support in critical patients with refractory hemorrhagic shock appears feasible considering tailored ECMO management strategies. Further investigation is needed to better elucidate the patient selection and ECLS management approaches.

Abstract
OBJECTIVES Surgical aortic valve replacement can be safely performed in people aged 80 years and older with early benefits on both symptomatic and prognostic ground. While new approaches are advocated to treat this elderly and frail population, data on long-term outcomes are not available. METHODS We conducted a retrospective analysis of 1870 patients aged 80 years and over who underwent first time surgical aortic valve replacement during the period 2000-2019. The Kaplan-Meier method was used to calculate survival and comparisons among groups were performed by log-rank test. Cox analysis was used to determine the independent risk factors for late mortality. RESULTS The patients' mean age was 84 years and 53% were male. Isolated aortic valve replacement was performed in 42% of the patients, and coronary artery bypass grafting (n = 956), mitral valve (n = 94) or aortic surgery (n = 69) were associated in the remaining cases. One hundred eighty-one patients (8%) sustained at least 1 postoperative complication (reopening for bleeding or tamponade 3%, renal replacement therapy 3%, new cerebral stroke 1.5%). In-hospital mortality was 3.2% in the overall population (60/1870) and 2.2% after isolated aortic valve replacement (18/790). Survival was 90%, 66%, 31% and 14% at 1, 5, 10 and 15 years, respectively, and was similar to the expected survival of a sex- and age-matched population (log-rank P = 0.96). A complicated postoperative course was an independent risk factor for mortality during the follow-up [hazard ratio 1.32 (1.03, 1.68), P = 0.026]. CONCLUSIONS Surgical aortic valve replacement can be performed with an acceptable early mortality rate and provides excellent long-term survival in people aged 80 years and older.

Abstract
Right ventricular failure (RVF) following left ventricular assist device (LVAD) implantation remains a major complication which may significantly impair patient outcome. The genesis of RVF is, however, multifactorial, and the mechanisms underlying such a condition have not been fully elucidated, making its prevention challenging and the course not always predictable. Although preoperative risks factors can be associated with RV impairment, the physiologic changes after the LV support, can still hamper the function of the RV. Current medical treatment options are limited and sometimes, patients with a severe post-LVAD RVF may be unresponsive to pharmacological therapy and require more aggressive treatment, such as temporary RV support. We retrieved 11 publications which we assessed and divided in groups based on the RV support [extracorporeal membrane oxygenation (ECMO), right ventricular assist device (RVAD), TandemHeart with ProtekDuo cannula]. The current review comprehensively summarizes the main studies of the literature with particular attention to the RV physiology and its changes after the LVAD implantation, the predictors and prognostic score as well as the different modalities of temporary mechanical cardio-circulatory support, and its effects on patient prognosis for RVF in such a setting. In addition, it provides a decision making of the pre-, intra and post-operative management in high- and moderate- risk patients.

Abstract
Hemostatic unbalance is often observed in patients with coronavirus disease 2019 (COVID-19), and patients with severe disease are at high risk of developing thromboembolic complications. Viscoelastic methods (VEMs), including thrombelastography (TEG) and thromboelastometry (TEM), provide data on the nature of hemostatic disturbance. In this systematic review, we assessed the performance of TEG and TEM in the assessment of blood coagulation and fibrinolysis in patients with COVID-19. PubMed, Scopus, Web of Science Core Collection, medRxiv, and bioRxiv were systematically searched for clinical studies evaluating TEG and/or TEM variables in COVID-19 individuals. Ten studies, with a total of 389 COVID-19 patients, were included, and VEMs were performed in 292 of these patients. Most patients (90%) presented severe COVID-19 and required mechanical ventilation. TEG and TEM variables showed that these patients displayed hypercoagulability and fibrinolysis shutdown, despite the use of appropriate thromboprophylaxis. However, the mechanism underlying these phenomena and their clinical significance in COVID-19 patients who developed thrombosis are still not clear. Further studies are warranted if VEMs might help to identify those at highest risk of thrombotic events and who therefore may derive the greatest benefit from antithrombotic therapy.

Abstract
Aims Because reported mortality on veno‐arterial (V‐A) extracorporeal life support (ECLS) substantially varies between centres, the aim of the current analysis was to assess the outcomes between units performing heart transplantation and/or implanting ventricular assist device (HTx/VAD) vs. non‐HTx/VAD units in patients undergoing V‐A ECLS for cardiogenic shock. Methods and results Systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses was performed using PubMed/MEDLINE databases until 30 November 2019. Articles reporting in‐hospital/30‐day mortality and centre's HTx/VAD status were included. In‐hospital outcomes and long‐term survival were analysed in subgroup meta‐analysis. A total of 174 studies enrolling n = 13 308 patients were included with 20 series performed in non‐HTx/VAD centres (1016 patients, 7.8%). Majority of patients underwent V‐A ECLS for post‐cardiotomy shock (44.2%) and acute myocardial infarction (20.7%). Estimated overall in‐hospital mortality was 57.2% (54.9–59.4%). Mortality rates were higher in non‐HTx/VAD [65.5% (59.8–70.8%)] as compared with HTx/VAD centres [55.8% (53.3–58.2%)], P < 0.001. Estimated late survival was 61.8% (55.7–67.9%) without differences between non‐HTx/VAD and HTx/VAD centres: 66.5% (30.3–1.02%) vs. 61.7% (55.5–67.8%), respectively (P = 0.797). No differences were seen with respect to ECLS duration, limb complications, and reoperations for bleeding, kidney injury, and sepsis. Yet, weaning rates were higher in HTx/VAD vs. non‐HTx/VAD centres: 58.7% (56.2–61.1%) vs. 48.9% (42.0–55.9%), P = 0.010. Estimated rate of bridge to heart transplant was 6.6% (5.2–8.3%) with numerical, yet not statistically significant, difference between non‐HTx/VAD [2.7% (0.8–8.3%)] as compared with HTx/VAD [6.7% (5.3–8.6%)] (P = 0.131). Conclusions Survival after V‐A ECLS differed according to centre's HTx/VAD status. Potentially different risk profiles of patients must be taken account for before definite conclusions are drawn.

Abstract
BACKGROUND Left ventricular free-wall rupture (LVFWR) is an uncommon but serious mechanical complication of acute myocardial infarction. Surgical repair, though challenging, is the only definitive treatment. Given the rarity of this condition, however, results after surgery are still not well established. The aim of this study was to review a multicenter experience with the surgical management of post-infarction LVFWR and analyze the associated early outcomes. METHODS Using the CAUTION (Mechanical Complications of Acute Myocardial Infarction: an International Multicenter Cohort Study) database, we identified 140 patients who were surgically treated for post-acute myocardial infarction LVFWR in 15 different centers from 2001 to 2018. The main outcome measured was operative mortality. Multivariate analysis was carried out by constructing a logistic regression model to identify predictors of postoperative mortality. RESULTS The mean age of patients was 69.4 years. The oozing type of LVFWR was observed in 79 patients (56.4%), and the blowout type in 61 (43.6%). Sutured repair was used in the 61.4% of cases. The operative mortality rate was 36.4%. Low cardiac output syndrome was the main cause of perioperative death. Myocardial rerupture after surgery occurred in 10 patients (7.1%). Multivariable analysis revealed that preoperative left ventricular ejection fraction (P < .001), cardiac arrest at presentation (P = .011), female sex (P = .044), and the need for preoperative extracorporeal life support (P = .003) were independent predictors for operative mortality. CONCLUSIONS Surgical repair of post-infarction LVFWR carries a high operative mortality. Female sex, preoperative left ventricular ejection fraction, cardiac arrest, and extracorporeal life support are predictors of early mortality.

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