Why the study?
Does the choice between balloon-expandable and self-expandable TAVI prostheses affect procedural success and clinical outcomes in patients with severe aortic stenosis?
Does the choice between balloon-expandable and self-expandable TAVI prostheses affect procedural success and clinical outcomes in patients with severe aortic stenosis?
This review highlights that while balloon-expandable TAVI valves currently demonstrate higher device success and fewer paravalvular leaks, prosthesis selection should be individualized based on patient anatomy and operator expertise.
Individualized TAVI prosthesis selection remains warranted; leaves open need for randomized long-term outcome comparisons.
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.
