NCT04734392

Brief Summary

Hypothesis of the study is that a modified and improved implantation protocol (regarding membranous septum length and implantation depth) will decrease the need for permanent pacemaker stimulation follow TAVR-procedures.

Study Population

The study cohort will comprise of patients referred to transcatheter aortic valve replacement. Patients will be prospectively and consecutively screened and enrolled at a tertiary high-volume center in Germany.

You may qualify if:

  • All patients referred to TAVR procedure due to severe aortic stenosis

You may not qualify if:

  • PM-implantation before TAVR
  • Valve-in-valve procedures
