Transcatheter Valve-in-Valve Implantation for Failing Bioprosthetic Valves: Small Bioprostheses (≤23 mm) Decrease Device Success Rate

Transcatheter valve-in-valve implantation for failed bioprosthetic heart valves.

BACKGROUND The majority of prosthetic heart valves currently implanted are tissue valves that can be expected to degenerate with time and eventually fail. Repeat cardiac surgery to replace these valves is associated with significant morbidity and mortality. Transcatheter heart valve implantation within a failed bioprosthesis, a "valve-in-valve" procedure, may offer a less invasive alternative. ...

Transcatheter valve-in-valve implantation for failed surgical bioprosthetic valves.

When bioprosthetic cardiac valves fail, reoperative valve replacement carries a higher risk of morbidity and mortality compared with initial valve replacement. Transcatheter heart valve implantation may be a viable alternative to surgical aortic valve replacement for high-risk patients with native aortic stenosis, and valve-in-valve (V-in-V) implantation has been successfully performed for fail...

Transcatheter Valve-in-Valve Implantation for Failing Bioprosthetic Triscupid Valves: Completing the Quest.

1537 Over the past decade, transcatheter aortic valve replacement (TAVR) has established itself as an important alternative to surgical aortic valve replacement for patients with symptomatic severe aortic stenosis who have a high or prohibitive surgical risk. The success of this breakthrough technology was propelled by data from several randomized, controlled trials and large registries. During...

Transcatheter aortic valve implantation in failed bioprosthetic surgical valves.

IMPORTANCE Owing to a considerable shift toward bioprosthesis implantation rather than mechanical valves, it is expected that patients will increasingly present with degenerated bioprostheses in the next few years. Transcatheter aortic valve-in-valve implantation is a less invasive approach for patients with structural valve deterioration; however, a comprehensive evaluation of survival after t...
