Early TAVR Explantation Due to a Large Mobile Leaflet Mass and Severe Prosthetic Valve Stenosis.

ABSTRACT:

Background

Transcatheter aortic valve replacement (TAVR) is a common treatment for aortic stenosis (AS). Although it is generally safe, its rising use has led to increased device failures and complications requiring surgery. Data on surgical explantation after TAVR remain limited.

Case presentation

An 85-year-old woman, 1-year post-TAVR, developed recurrent AS. Imaging revealed a mobile transvalvular mass and subvalvular pannus. Medical therapy failed, and because of stroke risk, she underwent TAVR explantation, subannular pannus resection, left ventricular outflow tract repair, and surgical aortic valve replacement. Histology confirmed leaflet thrombosis and valve deterioration.

Discussion

Surgical explantation after TAVR occurs in about 1% of cases. Among these, 47%
