Trends in SAVR with biological vs. mechanical valves in middle-aged patients: results from a French large multi-centric survey.

Background/introduction: Currently, despite continued issues with durability ( 1), biological prosthetic valves are increasingly chosen over mechanical valves for surgical aortic valve replacement (SAVR) in adult patients of all ages, at least in Western countries. For younger patients, this choice means assuming the risks associated with a redo SAVR or valve-in-valve procedure.

Purpose: To assess the use of mechanical vs.

Clinical utility of a deep-learning mortality prediction model for cardiac surgery decision making.

Objectives: The aim of this study using decision curve analysis (DCA) was to evaluate the clinical utility of a deep-learning mortality prediction model for cardiac surgery decision making compared with the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II and to 2 machine-learning models.

Methods: Using data from a French prospective database, this retrospective study evaluated all patients who underwent cardiac surgery in 43 hospital centers between January 2012 and December 2020. A receiver operating characteristic analysis was performed to compare the accuracy of the EuroSCORE II, machine-learning models, and an adapted Tabular Bidirectional Encoder Representations from Transformers deep-learning model in predicting postoperative in-hospital mortality.

Surgical aortic valve replacement in the modern era: Insights from the French Registry EPICARD.

Objective: We sought to assess the demographic changes and postoperative outcomes of surgical aortic valve replacement (SAVR) in recent years since the advent of trans-catheter aortic valve implantation (TAVI) in France.

Methods: Demographic, surgical data, and early outcomes of patients undergoing SAVR for AS were reviewed from The French registry EPICARD before (2007-2012) and after (2013-2018) approval of TAVI by French health authorities. We included patients with less than 20% of missing data per variable and per patient.

Influence of stentless versus stented valves on ventricular remodeling assessed at 6 months by magnetic resonance imaging and long-term follow-up.

Background: To compare the effect of stented versus stentless bioprostheses on left ventricular remodeling and assess their impact on long-term survival.

Methods: From January 2002 to December 2009, 62 severe aortic stenosis patients without coronary artery disease were randomized for bioprosthetic aortic valve replacement. After randomization, a cross-over was possible based on intraoperative data.
