TAVI

Pronunciation: TAH-vee

Also written as: TAVI — Transcatheter Aortic Valve Implantation

Minimally invasive procedure to replace aortic valve via catheter approach.

Full Definition

Transcatheter Aortic Valve Implantation (TAVI) is a minimally invasive cardiac procedure where a prosthetic aortic valve is delivered and deployed via catheter, typically through femoral artery access. The procedure is performed under fluoroscopic and echocardiographic guidance, allowing treatment of severe aortic stenosis in patients who are high-risk or inoperable for traditional surgical valve replacement. Pre-procedural CT imaging is essential for sizing and procedural planning.

Usage

Usage note: TAVI and TAVR are used interchangeably, though TAVI is more common in European literature.
