Electrophysiologic HV-interval as a Predicor for Permanent Pacemaker Implantation After TAVI

Klinik für Kardiologie, Pneumologie und Angiologie25 enrolled

Overview

The development of a high grade AV-block is a frequent complication associated with transcatheter aortic valve implantation (TAVI). Patients who were suitable for TAVI will be enrolled in this study. The HV-interval will be determined before and immediately after implantation. The hypothesis is that a prolonged HV-interval is associated with a high rate of complete AV-block following TAVI.

Outcomes

Primary Outcomes

Determination of HV interval

HV-interval will be determined by a 5F quadripolar electrode catheter with a CRD-2 curve configuration. Intracardiac signals will be assessed and determined before and after implantation.

Time frame: Changes in Baseline to 24 hours

Secondary Outcomes

AV-block development after 1 month, 6 months and 12 months

Time frame: 1 month, 6 months and 12 months
