Post‐TAVR conduction abnormalities leading to permanent pacemaker implantation: Risk factors, prevention, and management

Abstract

AbstractTranscatheter aortic valve replacement (TAVR) often leads to conduction abnormalities, necessitating pacemaker implantation. This review of 38 meta‐analyses identified preexisting right bundle branch block (RBBB), LAHB, and new‐onset left bundle branch block as key risk factors, with a higher PPM risk in male and older patients. Procedural factors like transfemoral access and self‐expandable valves also increase this risk. Prevention focuses on tailoring TAVR to individual electrophysiological and anatomical profiles. However, there's a lack of consensus in managing these conduction disturbances post‐TAVR, highlighting the need for further research and standardized treatment strategies.
