The systemic impairment that accompanies liver cirrhosis is known to carry a significant burden on death and postoperative complications in cardiovascular interventions. This review analyzes the impact of liver cirrhosis on short‐ and long‐term outcomes after cardiac surgery and percutaneous procedures, providing an evidence‐based guidance in the decision‐making process and perioperative management of these patients. Several parameters should be considered by the heart teams when assessing eligibility, indications for intervention, and perioperative management of these patients. Life expectancy, long‐term procedural outcomes, Child–Pugh or the Model for End‐Stage Liver Disease score, presence of gastroesophageal varices and hepatic venous pressure gradient were extrapolated as the main determinants in decision making in patients with cirrhosis. Assessment and treatment of gastroesophageal varices is mandatory. Hepatic venous pressure gradient values >20 mm Hg preclude patients from a surgical approach. Considering the poor prognosis of advanced liver cirrhosis, futile treatments should be avoided. A multidimensional heart team approach involving surgical, cardiologic, anesthesiologic, hepatological, and medical considerations is recommended.

Background Aortic valve stenosis (AVS) represents the most prevalent primary valvular lesion necessitating surgical intervention or transcatheter intervention in Europe and North America. Its prevalence is increasing at a rapid rate as a consequence of the ageing population. A variety of mechanical interventions are available to determine the management of AVS; however, there is currently a paucity of robust data with which to perform a comparative analysis of the efficacy of surgical aortic valve replacement (SAVR) and that of conventional stented xenograft bioprostheses (BP) or sutureless aortic valves (SAV) and transcatheter aortic valve implantation (TAVI). The present study aims to compare the effectiveness and clinical outcomes of SAVR using BP or SAV technique and TAVI in patients with severe AVS. Methods and analysis A collaboration between three cardiac surgery centres across two European countries has resulted in the conception of the Transcatheter Aortic Valve Implantation vs Surgical Aortic Valve Replacement trial. This prospective non-randomised trial is designed to evaluate the long-term outcomes of TAVI in comparison to SAVR for AVS in patients at risk of severe valve obstruction. The registry will enrol successive patients who have undergone mechanical intervention for AVS between January 2015 and December 2025. Investigators will assess the difference between replacement procedures for both the standard surgical approach and the transcatheter procedure. The principal clinical outcome under consideration will be the composite degree of all-cause mortality, ischaemic stroke or rehospitalisation at 10 years. The present study will also have a number of secondary endpoints, including all-cause mortality, followed by functional status, hospitalisation, neurocognition, physiological measures (echocardiographic assessment), adverse events and reoperation. Ethics and dissemination It is hypothesised that the nature of the trials will serve to minimise bias related to institutional volume and surgical experience. Each participating centre is required to have an aortic valve programme that enables proper follow-up and management of any late aortic events following replacement surgery for the AVS. The data collected will provide valuable insight into the comparative effectiveness of various surgical approaches, both standardised and advanced, in aortic valve surgery and TAVI. This comprehensive analysis will contribute significantly to the development of robust international guidelines. Trial registration number Clinical Trial Gov.Com. ID: NCT05261204 IRB. ID: 2022011057

Background Secondary mitral regurgitation (SMR) is a condition affecting the left ventricle (LV) rather than the mitral valve (MV). If the MV remains structurally unchanged, enlargement of the LV or impairment of the papillary muscles can occur. Several mechanical interventions are available to dictate the resolution of MR. However, there is a lack of robust data to compare MV replacement, MV repair (including subvalvular repair) and transcatheter mitral valve procedures (TMVp). This study aims to compare the effectiveness and clinical outcomes of TMVp using the edge-to-edge mitral valve repair technique and standard surgical mitral valve procedures in patients with SMR. Methods and analysis Five cardiac surgery centres from four European countries and Japan have collaborated to create a multicentre observational registry (TEERMISO). The registry will enrol consecutive patients who underwent mechanical intervention for SMR between January 2007 and December 2023. The investigators assessed the difference between replacement and repair for both the standard surgical approach and the transcatheter procedure. The main clinical outcome will be the degree of LV remodelling as assessed by the Left Ventricular End-Diastolic Volume Index at 10 years. The study will measure several secondary endpoints, including all-cause mortality as the primary endpoint, followed by functional status, hospitalisation, neurocognition, physiological measures (echocardiographic assessment), adverse events and reoperation. Ethics and dissemination Ethics approval was obtained in Montpellier University Hospital on 24 May 2022 (Institutional Review Board Approval Number: IRB-MTP_2022_05_202201143). The results of the main study and each sub-analysis will be submitted for publication in a peer-reviewed journal. Trial registration number NCT05090540 .

Background: Secondary mitral regurgitation (SMR) is characterized by a pathological process impacting the left ventricle (LV) as opposed to the mitral valve (MV). In the absence of structural alterations to the MV, the expansion of the LV or impairment of the papillary muscles (PMs) may ensue. A number of technical procedures are accessible for the purpose of determining the optimal resolution for MR. Nevertheless, there is a dearth of rigorous data to facilitate a comparative analysis of MV replacement, MV repair (including subvalvular repair), and transcatheter mitral valve interventions (TMV-Is). The objective of this investigation is to evaluate and compare the efficacy and clinical outcomes of transcatheter mitral valve repair (TMV-r) utilizing the edge-to-edge mitral valve repair (TEER) procedure in comparison to conventional surgical mitral valve interventions (S-SMVis) in patients with secondary mitral regurgitation. Methods and analysis: A consortium of five cardiac surgery institutions from four European states and Japan have joined forces to establish a multicenter observational registry, designated TEERMISO. Patients who underwent technical procedures for SMR between January 2007 and December 2023 will be enrolled consecutively into the TEERMISO registry. The investigation team evaluated the comparative efficacy of replacement and repair techniques, utilizing both the standard surgical methodology and the transcatheter intervention. The primary clinical outcome will be the degree of left ventricular remodeling, as assessed by the left ventricular end-diastolic volume index, at 10 years. The forthcoming research will assess a variety of secondary endpoints, among which all-cause mortality will be the primary endpoint. Subsequent assessments will be made in the following order: functional status, hospitalization, neurocognition, physiological measures (echocardiographic assessment), occurrence of adverse clinical incidents, and reoperation. Ethics and dissemination: The multicenter design of the database is anticipated to reduce the potential for bias associated with institutional caseload and surgical experience. All participating centers possess an established mitral valve protocol that facilitates comprehensive follow-up and management of any delayed mitral complications following replacement surgery or surgical repair of the secondary mitral regurgitation. The data collected will provide insights into the impact of diverse surgical approaches on standard mitral valve surgery and TEER. This will facilitate the evaluation of LV remodeling over the course of long-term post-procedural follow-up. Trial Registration: ClinicalTrials.gov ID: NCT05090540; IRB ID: 202201143

Abstract Background Previous meta‐analyses combining randomized and observational evidence in cardiac surgery have shown positive impact of enhanced recovery protocols after surgery (ERAS) on postoperative outcomes. However, definitive data based on randomized studies are missing, and the entirety of the ERAS measures and pathway, as recently systematized in guidelines and consensus statements, have not been captured in the published studies. The available literature actually focuses on “ERAS‐like” protocols or only limited number of ERAS measures. This study aims at analyzing all randomized studies applying ERAS‐like protocols in cardiac surgery for perioperative outcomes. Methods A meta‐analysis of randomized controlled trials (RCTs) comparing ERAS‐like with standard protocols of perioperative care was performed (PROSPERO registration CRD42021283765). PRISMA guidelines were used for abstracting and assessing data. Results Thirteen single center RCTs ( N = 1704, 850 in ERAS‐like protocol and 854 in the standard care group) were selected. The most common procedures were surgical revascularization (66.3%) and valvular surgery (24.9%). No difference was found in the incidence of inhospital mortality between the ERAS and standard treatment group (risk ratio [RR] 0.61 [0.31; 1.20], p = 0.15). ERAS was associated with reduced intensive care unit (standardized mean difference [SMD] −0.57, p < 0.01) and hospital stay (SMD −0.23, p < 0.01) and reduced rates of overall complications when compared to the standard protocol (RR 0.60, p < 0.01) driven by the reduction in stroke (RR 0.29 [0.13; 0.62], p < 0.01). A significant heterogeneity in terms of the elements of the ERAS protocol included in the studies was observed. Conclusions ERAS‐like protocols have no impact on short‐term survival after cardiac surgery but allows for a faster hospital discharge while potentially reducing surgical complications. However, this study highlights a significant nonadherence and heterogeneity to the entirety of ERAS protocols warranting further RCTs in this field including a greater number of elements of the framework.

Introduction: Patients requiring postcardiotomy veno-arterial extracorporeal membrane oxygenation (V-A-ECMO) have a high risk of early mortality. In this analysis, we evaluated whether any interinstitutional difference exists in the results of postcardiotomy V-A-ECMO. Methods: Studies on postcardiotomy V-A-ECMO were identified through a systematic review for individual patient data (IPD) meta-analysis. Analysis of interinstitutional results was performed using direct standardization, estimation of observed/expected in-hospital mortality ratio and propensity score matching. Results: Systematic review of the literature yielded 31 studies. Data from 10 studies on 1269 patients treated at 25 hospitals were available for the present analysis. In-hospital mortality was 66.7%. The relative risk of in-hospital mortality was significantly higher in six hospitals. Observed versus expected in-hospital mortality ratio showed that four hospitals were outliers with significantly increased mortality rates, and one hospital had significantly lower in-hospital mortality rate. Participating hospitals were classified as underperforming and overperforming hospitals if their observed/expected in-hospital mortality was higher or lower than 1.0, respectively. Among 395 propensity score matched pairs, the overperforming hospitals had significantly lower in-hospital mortality (60.3% vs 71.4%, p = 0.001) than underperforming hospitals. Low annual volume of postcardiotomy V-A-ECMO tended to be predictive of poor outcome only when adjusted for patients’ risk profile. Conclusions: In-hospital mortality after postcardiotomy V-A-ECMO differed significantly between participating hospitals. These findings suggest that in many centers there is room for improvement of the results of postcardiotomy V-A-ECMO.

Background Differences in quality of life (QoL) after coronary artery bypass grafting (CABG) compared with percutaneous coronary intervention (PCI) are not well characterized. We aimed to compare the short‐ and long‐term effects of CABG versus PCI on QoL. Methods and Results We performed a systematic review and meta‐analysis of randomized controlled trials comparing CABG versus PCI using the Seattle Angina Questionnaire (SAQ)‐Angina Frequency, SAQ‐QoL, SAQ‐Physical Limitations, EuroQoL‐5D, and Short‐Form Questionnaire. We calculated mean changes within each group from baseline to 1, 6, 12, and 36 to 60 months (latest follow‐up) and the weighted mean differences between groups using inverse‐variance methods. A total of 10 760 patients were enrolled in 5 trials. From baseline to 12 months and 36 to 60 months, the mean change in SAQ‐Angina Frequency was >22 points (95% CI, 21.0–25.6) after both PCI and CABG. The mean difference in SAQ‐Angina Frequency was similar between procedures at 1 month and at 36 to 60 months but favored CABG at 12 months (1.97 [95% CI, 0.68–3.26]). SAQ‐QoL favored PCI at 1 month (−2.92 [95% CI, −4.66 to −1.18]) and CABG at 6 (2.50 [95% CI, 1.02–3.97]), 12 (3.30 [95% CI, 1.78–4.82]), and 36 to 60 months (3.17 [95% CI, 0.54 5.80). SAQ‐Physical Limitations (−12.61 [95% CI, −16.16 to −9.06]) and EuroQoL‐5D (−0.07 [95% CI, −0.08 to −0.07) favored PCI at 1 month. Short‐Form Questionnaire‐Physical Component favored CABG at 12 months (1.18 [95% CI, 0.46–1.90]). Conclusions Both PCI and CABG improved long‐term disease‐specific and generic QoL.

Aortic dissection is a clinicopathological entity caused by rupture of the intima, leading to a high mortality if not treated. Over time, diagnostic and investigative methods, antihypertensive therapy, and early referrals have resulted in improved outcomes according to registry data. Some data have also emerged from recent studies suggesting a link between Human Cytomegalovirus (HCMV) infection and aortic dissection. Furthermore, the use of microRNAs has also become increasingly widespread in the literature. These have been noted to play a role in aortic dissections with elevated levels noted in studies as early as 2017. This review aims to provide a broad and holistic overview of the role of miRNAs, while studying the role of HCMV infection in the context of aortic dissections. The roles of long non-coding RNAs, circular RNAs, and microRNAs are explored to identify changes in expression during aortic dissections. The use of such biomarkers may one day be translated into clinical practice to allow early detection and prognostication of outcomes and drive preventative and therapeutic options in the future.

Introduction Postcardiotomy veno-arterial extracorporeal membrane oxygenation (V-A-ECMO) is associated with significant mortality. Identification of patients at very high risk for death is elusive and the decision to initiate V-A-ECMO is based on clinical judgment. The prognostic impact of pre-V-A-ECMO arterial lactate level in these critically ill patients has been herein evaluated. Methods A systematic review was conducted to identify studies on postcardiotomy VA-ECMO for the present individual patient data meta-analysis. Results Overall, 1269 patients selected from 10 studies were included in this analysis. Arterial lactate level at V-A-ECMO initiation was increased in patients who died during the index hospitalization compared to those who survived (9.3 vs 6.6 mmol/L, p < 0.0001). Accordingly, in hospital mortality increased along quintiles of pre-V-A-ECMO arterial lactate level (quintiles: 1, 54.9%; 2, 54.9%; 3, 67.3%; 4, 74.2%; 5, 82.2%, p < 0.0001). The best cut-off for arterial lactate was 6.8 mmol/L (in-hospital mortality, 76.7% vs. 55.7%, p < 0.0001). Multivariable multilevel mixed-effect logistic regression model including arterial lactate level significantly increased the area under the receiver operating characteristics curve (0.731, 95% CI 0.702–0.760 vs 0.679, 95% CI 0.648–0.711, DeLong test p < 0.0001). Classification and regression tree analysis showed the in-hospital mortality was 85.2% in patients aged more than 70 years with pre-V-A-ECMO arterial lactate level ≥6.8 mmol/L. Conclusions Among patients requiring postcardiotomy V-A-ECMO, hyperlactatemia was associated with a marked increase of in-hospital mortality. Arterial lactate may be useful in guiding the decision-making process and the timing of initiation of postcardiotomy V-A-ECMO.
