Pacing Dependence at 1 Year Follow-up in Patients Implanted With a Pacemaker After TAVR: a Multicenter Observational Study

What this Trial Is About

Researchers are studying patients who have had a transcatheter aortic valve replacement (TAVR) and subsequently required permanent pacemaker implantation due to high-grade conduction disorders. This observational study aims to evaluate how many of these patients remain dependent on their pacemaker stimulation one year after implantation. The study also explores the types of conduction disorders involved, the initial reasons for pacemaker implantation, and the characteristics of patients who do or do not depend on pacing over time. The study focuses on patients who needed pacemakers implanted after their TAVR procedure. Researchers will observe these patients without altering their treatment. They will assess effective pacemaker stimulation at 3 months and 1 year after implantation. The study will also document serious clinical events such as mortality, stroke, heart failure, rehospitalizations for cardiac causes, and pacemaker-related complications during follow-up. Participants will be monitored through clinical evaluations and electrocardiogram (ECG) assessments to determine pacing dependency and cardiac status over time. The main outcome measured is pacing dependency at one year post-implantation. The study aims to provide clearer guidance on when permanent pacemaker implantation is truly needed after TAVR. The total participation duration includes follow-up assessments at 3 months and 12 months after pacemaker implantation.
