Transcatheter Technologies for Valvular Replacement: an Update

Surg Technol Int. 2018 Jun 1:32:190-199.

Abstract

This report provides a brief overview of the basic principles, recent advances, and recommendations for the treatment of severe aortic stenosis with transcatheter aortic valve replacement (TAVR) in adults. Approaches that avoid neurological, cardiac and peripheral vascular complications have been developed. In addition, TAVR can be performed in intermediate- and low-risk patients. However, these procedures require specialized training and may not allow for complete resolution of the underlying issue. Even if cardiologists learn to perform the procedure and despite advancements in device technology, TAVR is still susceptible to structural valve degeneration, thrombosis and late cerebral embolization. To date, TAVR has shown no consistent advantage over surgical aortic valve replacement (SAVR) in intermediate- and low-risk patients.
