Key result
Cutting frame wire enables safe transcatheter balloon-expandable valve removal without root disruption in ~75% of cases.
Why the study?
Some patients require surgical aortic valve replacement after TAVR due to structural valve deterioration or prosthetic valve endocarditis, but data on redo surgery after TAVR are limited.
Case Report (n=4)
No
May facilitate safer TAVR explantation in redo surgery; hypothesis-generating and requires larger validation before practice change.
Transcatheter aortic valve replacement (TAVR) is a common surgical intervention in intermediate- and high-risk patients with severe aortic stenosis (AS).1 After TAVR, some patients develop structural valve deterioration (SVD) or prosthetic valve endocarditis and may require surgical aortic valve replacement (SAVR), although though this has been reported only rarely.2,3 Owing to adhesion of the valve to the surrounding tissue, removing a TAVR valve poses a great risk, because it may disrupt the aortic root.

Nakazato et al. (2020) conducted a case report in Failed transcatheter aortic valve replacement requiring surgical aortic valve replacement (n=4). Surgical removal of TAVR valve by cutting the frame wire and releasing radial force was evaluated on Safe removal of TAVR valve and hospital survival.
