Successful aortic valve replacement by overexpanding a SAPIEN transcatheter heart valve for a large aortic annulus (>900 mm²): a case report.

ABSTRACT:

Background

There are limited commercial valve sizes available for transcatheter aortic valve implantation (TAVI). This makes it challenging or even prohibitive to perform TAVI on large aortic annuli.

Case summary

A 78-year-old male with known low-flow, low-gradient severe aortic stenosis presented with progressive dyspnoea, chest pressure, and decompensated heart failure. Successful off-label TAVI was performed for tricuspid aortic valve stenosis with an aortic annulus of >900 mm². An Edwards S3 29 mm valve was overexpanded with an extra 7 mL of volume at valve deployment. No complications occurred, and only trivial paravalvular leak was seen following implantation. The patient died from a non-cardiovascular cause 8 months following the procedure.
