Commissural and coronary alignment of the Venus-A valve after transcatheter aortic valve replacement: a retrospective cross-sectional study

ABSTRACT:

Background

Previous studies have shown that neo-commissural orientation of transcatheter heart valve (THV) can influence coronary obstruction during transcatheter aortic valve replacement (TAVR), long-term durability of THV, and coronary artery access for reintervention after TAVR. Specific initial orientations of Evolut R/Pro and Acurate Neo aortic valves can improve commissural alignment. However, the method of achieving commissural alignment with the Venus-A valve remains unknown. Therefore, this study aimed to evaluate the extent of commissural and coronary alignment of the Venus-A self-expanding valve after TAVR using a standard system delivery technique.

Methods

A retrospective cross-sectional study was performed. At the time of enrollment, patients who underwent pr
