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

Electrophysiologic HV-interval as a Predicor for Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation With a Self-expanding Bioprosthesis

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.

Inclusion Criteria:

• symptomatic aortic valve stenosis
• patients screened for TAVI
• written informed consent

Exclusion Criteria:

• unconsciousness, not able to consent
• < 18 years
• permanent pacemaker
