Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure used to treat aortic valve stenosis, a condition where the heart's aortic valve narrows, restricting blood flow. During TAVR, a new valve is inserted through a catheter, usually through a blood vessel in the leg, and guided to the heart. This approach reduces recovery time and hospital stay compared to traditional open-heart surgery. The procedure is typically recommended for patients who are at high risk for complications from surgery. TAVR has been shown to improve symptoms and quality of life, allowing patients to return to their daily activities more quickly.
