Elastic Recoil and Deployment Asymmetry of the Transcatheter Heart Valve in Bicuspid Versus Tricuspid Anatomy.

ABSTRACT:

Background

Data supporting the use of transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve (BAV) is limited compared to tricuspid aortic valve (TAV) anatomy, as the BAV anatomy poses unique challenges to prosthesis expansion and symmetric deployment.

Aims

We aim to compare the acute recoil and asymmetry of the SAPIEN-3 valve between BAV and TAV anatomies and their impact on procedural outcomes.

Methods

We conducted a single-center study of patients who underwent TAVR with the SAPIEN-3 valve. We measured acute recoil, deployment asymmetry, and length asymmetry from intraprocedural angiogram before and after postdilation, as well as before and after predilation. Hemodynamic and procedural outcomes were studied.
