  Purpose

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.


Condition
Symptomatic Aortic Valve Stenosis

Study Type: Observational
Study Design: Observational Model: Cohort
Official Title: Electrophysiologic HV-interval as a Predicor for Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation With a Self-expanding Bioprosthesis

Further study details as provided by Klinik für Kardiologie, Pneumologie und Angiologie, Heinrich-Heine University, Duesseldorf:

Primary Outcome Measures:
  • Determination of HV interval [ Time Frame: Changes in Baseline to 24 hours ]
    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.


Secondary Outcome Measures:
  • AV-block development after 1 month, 6 months and 12 months [ Time Frame: 1 month, 6 months and 12 months ]

Other Outcome Measures:
  • cardiovascular mortality [ Time Frame: 1 month, 6 months and 12 months ]

Enrollment: 25
Study Start Date: December 2012
Study Completion Date: November 2013
Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
