TAV-in-TAV to Rescue Suboptimal Index TAVR: The Critical Role of Anatomy.

ABSTRACT:

Background

Suboptimal transcatheter aortic valve replacement (TAVR) positioning can lead to inadequate sealing between the prosthesis and the native annulus, resulting in significant paravalvular leak (PVL).

Case summary

A 75-year-old woman underwent TAVR with an ACURATE neo2 valve that was complicated by severe intraprocedural aortic regurgitation and hemodynamic instability, resulting in prompt deployment of the valve, with residual moderate PVL. Initial symptomatic relief was short-lived owing to progressive heart failure. Anatomical evaluation revealed substantial constraints, guiding the successful implantation of a high-positioned Sapien 3 Ultra transcatheter valve-in-valve (TAV-in-TAV). Meticulous coronary protection and iterative balloon postdilatation resolved PVL w
