Development of advanced conduction disturbances following balloon-expandable transcatheter aortic valve replacement leads to poorer clinical outcomes.

ABSTRACT:

Background

Transcatheter aortic valve replacement (TAVR) is a reliable method of treating patients with severe aortic stenosis, but is associated with postprocedure conduction defects.

Objective

The purpose of this study was to compare clinical outcomes in patients who developed advanced conduction defects post-TAVR to those who did not.

Methods

We conducted a retrospective chart review of 243 patients who underwent balloon-expandable TAVR with the Edwards Sapien valve to determine the incidence of advanced conduction defects in our cohort. We compared clinical outcomes including overall mortality, improvement in symptomatology, and improvement in left ventricular ejection fraction.

Results

Among the 243 patients included in the study, 9.1% (22/243) required pe
