TAVR

Pronunciation: TAV-er

Also written as: TAVR — Transcatheter Aortic Valve Replacement

Minimally invasive procedure to replace a diseased aortic valve using catheter-based techniques.

Full Definition

Transcatheter Aortic Valve Replacement is a minimally invasive cardiac procedure that replaces a stenotic or regurgitant aortic valve without open-heart surgery. The procedure involves inserting a collapsible replacement valve through a catheter, typically via femoral, subclavian, or transapical access. TAVR has become the preferred treatment for high-risk surgical patients and is increasingly used in intermediate and low-risk populations. Pre-procedural imaging with CT and echocardiography is essential for valve sizing and access planning.

Usage

Usage note: Often used interchangeably with TAVI in clinical documentation.
