Surgical valve explantation after TAVR tied to high short-term mortality

Reuters Health - 20/10/2020 - Surgical valve explantation following successful transcatheter aortic-valve replacement (TAVR) because of factors including structural deterioration is rare but risky, according to a study of Medicare claims data. As Dr. Tsuyoshi Kaneko of Brigham and Women's Hospital, in Boston, told Reuters Health by email, "the incidence of TAVR explant was low, but the mortality was high. It remains to be seen whether surgeon experience and lower patient risk profile will lower the mortality in the future, and its implications on lifetime management of aortic stenosis with TAVR and surgical aortic-valve replacement (SAVR)." As TAVR expands to younger patients, valve reintervention is inevitable in the setting of possible structural valve deterioration, endocarditis, or significant paravalvular leakage, Dr. Kaneko and colleagues note in the Journal of the American College of Cardiology. For most patients who require valve reintervention after ...
