Abstract

Few studies have reported their experience in explantation of a transcatheter heart valve. We found 2,100 patients who underwent transcatheter aortic valve implantation (TAVI) from 2013 through 2021. Of 2,100, a total of 17 patients underwent surgical aortic valve replacement after TAVI, including surgical bailout. The mean age was 78.3 years. Co-morbidities were very frequent, including coronary artery disease (70.6%), atrial fibrillation (52.9%), cerebrovascular disease (47.1%), and pulmonary hypertension (41.2%). A history of cardiac surgery was observed in 6 patients (35.3%). The mean predicted risk of mortality at the time of TAVI was 7.7%. Surgical bailout was the most common indication of valve explantation (n = 8, 47.1%), followed by infective endocarditis (n = 4, 23.5%) and paravalvular leak (n = 2, 11.8%). The valve-in-valve TAVI was not feasible because of endocarditis, paravalvular leak, and history of valve-in-valve TAVI. Overall, 13 (76.5%) were performed urgently or emergently, and 10 (58.9%) required aortic root reconstruction. The mean cardiopulmonary bypass time was 158.5 minutes. In-hospital mortality was 41.2%. Transcatheter heart valve explantation continues to be rare; however, these data will continue to be informative as TAVI explantations will become more common with time.
