Does Rhythm Recover after Pacemaker Implantation for Atrioventricular Conduction Disorder after Sutureless Aortic Valve Replacement?

Abstract

Objectives: The majority of patients receiving permanent pacemaker (PM) implantation after conventional aortic valve replacement (AVR) do not recover from atrioventricular (AV) conduction disorder. The new generation of self-expandable sutureless aortic valve prostheses offers benefits in terms of reduced cardiac ischemia times, but leads to a higher rate of postoperative AV conduction disorders. Whether these patients recover from AV conduction disorders is not clear. This study analyzes the long-term PM dependency and recovery from AV conduction disorders during follow-up in patients receiving sutureless aortic valve prosthesis.
