TAVR

Pronunciation: TAV-er

Also written as: TAVR — Transcatheter Aortic Valve Replacement

A minimally invasive procedure to replace a diseased aortic valve using a catheter-delivered prosthetic valve.

Full Definition

Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive cardiac intervention that allows replacement of a stenotic or regurgitant aortic valve without open-heart surgery. The procedure involves advancing a collapsible bioprosthetic valve through peripheral arteries to the aortic position, where it is deployed within the existing diseased valve. TAVR has revolutionized treatment for high-risk surgical candidates and elderly patients. The procedure requires careful pre-procedural imaging and sizing to ensure optimal valve positioning and function.

Usage

Usage note: TAVR and TAVI are used interchangeably; ensure consistency within documents.
