OPINION: Future of transcatheter aortic valve implantation — evolving clinical indications
| Accumulating clinical experience and technological improvements have provided the basis for transcatheter aortic valve implantation (TAVI) to emerge as a well-established means for treating patients with severe symptomatic aortic stenosis at high or prohibitive surgical risk. During this decade, TAVI has emerged as a valid alternative to surgical aortic valve replacement in patients at intermediate surgical risk, and several studies are currently being performed to evaluate the role of TAVI in patients at low surgical risk. Furthermore, promising, but preliminary, data are emerging on the efficacy of TAVI for treating patients with bicuspid aortic valve disease, as well as patients with pure aortic regurgitation. In this Perspectives article, we summarize the evolving indications for TAVI, and give our opinion on the future perspectives for this procedure.
