Specific indications for TAVI

Abstract

ABSTRACT Transcatheter aortic valve implantation (TAVI) is the most commonly used structural technique in the field of interventional cardiology. Initially, this procedure was only used in patients with severe symptomatic aortic stenosis and prohibitive risk for surgical aortic valve replacement. In just 1 decade, TAVI indications have extended to patients at intermediate surgical risk. More recently, the results of the PARTNER 3 and Evolut Low Risk clinical trials has opened that door for patients at low surgical risk. However, there are still some controversial indications that represent the boundaries of TAVI including patients at lower risk with bicuspid aortic valve, valve-in-valve procedures, pure aortic regurgitation or severe valvular heart disease after healed infective endocarditis. Our objective was to summarize the evidence avilable –mostly case series and retrospective registries– that supports the use of TAVI for these new indications.
