Selection of TAVI prostheses: Do we really have the CHOICE?

Abstract

Transcatheter aortic valve implantation (TAVI) has developed rapidly in the past few years and is expected to expand further in the near future. A reasonable number of large multicentre registries and randomised clinical trials have been performed, which have provided a considerable quality of evidence necessary to ensure optimal use and optimal patient outcomes. Currently, a large number of different valves have been approved in Europe, with a varying amount of supporting evidence, which complicates the process of valve type selection. This article reviews the evolution and fundamental aspects of prosthesis type selection in patients undergoing TAVI, and summarises the most relevant clinical studies in this context.
