TAVI
Pronunciation: TAV-ee
Also written as: TAVI — Transcatheter Aortic Valve Implantation
Minimally invasive procedure replacing a stenotic aortic valve via catheter-based delivery, avoiding open-heart surgery.
Full Definition
Transcatheter Aortic Valve Implantation (TAVI), also known as TAVR (Transcatheter Aortic Valve Replacement), is a minimally invasive procedure for treating severe aortic stenosis. The technique involves delivering a prosthetic valve through a catheter system, typically via transfemoral, transapical, or transaortic approaches. In cardiovascular research, TAVI has revolutionized treatment paradigms for high-risk and inoperable patients with severe aortic stenosis, with ongoing trials expanding indications to intermediate and low-risk populations. Clinical endpoints in TAVI studies include procedural success, mortality, stroke, and paravalvular regurgitation.
Usage
Usage note: TAVI and TAVR are interchangeable; specify access route when relevant to study design.
