TAVR
Also written as: TAVR — Transcatheter Aortic Valve Replacement
A minimally invasive procedure to replace an aortic valve using catheter-based delivery.
Full Definition
Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive cardiac procedure that replaces a diseased aortic valve without open-heart surgery. The procedure involves inserting a catheter through an artery and delivering a prosthetic valve to the heart. TAVR has revolutionized treatment for high-risk patients with severe aortic stenosis who were previously considered inoperable. Imaging plays a crucial role in patient selection, procedural planning, and post-procedural assessment of valve function and positioning.
Usage
Usage note: Often confused with TAVI; both terms refer to the same procedure but TAVR is preferred in American literature.
