Cardiac Insufficiency

Several Drugs used in routine care in oncology induce rare but often severe or fatal cardiovascular or metabolic side effects. This study will investigate, evaluate, report and treat the cardiovascular side effects of anticancer drugs, through a specific cardiovascular routine checkup and follow-up taking place in several Cardio-oncology programs throughout France. The different including centers will be: Assistance Publique - Hôpitaux de Paris (APHP.6: Pitié-Salpétrière, Saint Antoine and Tenon's hospitals, Paris, France).

This is a multi-center, prospective, single-blind, randomized controlled clinical trial to evaluate the efficacy and safety of Bachmann bundle pacing (BBP) in preventing new-onset atrial fibrillation (AF) in patients with chronic cardiac insufficiency who have indications for cardiac resynchronization therapy with left bundle branch pacing (CRT/LBBP) or implantable cardioverter defibrillator (ICD) implantation. A total of 110 eligible patients will be randomly assigned 1:1 to the BBP group or the traditional right atrial appendage (RAA) pacing group. All patients will receive guideline-directed medical therapy (GDMT) for at least 3 months and standardized follow-up for 12 months after device implantation. The primary endpoint is the incidence of new-onset AF within 12 months after implantation. Secondary endpoints include time to first new-onset AF, procedural success rate, changes in cardiac function parameters, and incidence of adverse events. This study aims to provide high-level evidence-based medical evidence for BBP as a new atrial pacing strategy to prevent AF in heart failure patients.
