TAVI
Pronunciation: TAV-ee
Also written as: TAVI — Transcatheter Aortic Valve Implantation
Minimally invasive procedure to replace aortic valve without open-heart surgery.
Full Definition
Transcatheter Aortic Valve Implantation (TAVI), also known as TAVR (Transcatheter Aortic Valve Replacement), is a minimally invasive procedure used to treat severe aortic stenosis in patients who are at high risk for traditional surgical valve replacement. The procedure involves inserting a collapsible bioprosthetic valve through a catheter, typically via the femoral artery, and deploying it within the diseased native aortic valve. TAVI has revolutionized treatment for elderly patients and those with multiple comorbidities, offering shorter recovery times and reduced procedural risks compared to open-heart surgery while providing excellent hemodynamic outcomes.
Usage
Usage note: TAVI and TAVR are interchangeable; specify approach route when relevant.
