Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure used to replace a diseased or malfunctioning aortic valve in patients who are not candidates for traditional open-heart surgery. The procedure involves threading a catheter through a blood vessel to the heart, where a prosthetic valve is inserted and positioned in place of the old valve.

TAVR is commonly used in patients with severe aortic stenosis, providing an effective solution to improve heart function, reduce symptoms, and improve overall quality of life.
