TAVR is a minimally invasive surgical treatment for severe aortic stenosis. Aortic stenosis occurs when the aortic valve becomes stiff, narrows and restricts blood flow, forcing the heart to work harder.
During TAVR, interventional cardiologists make small incisions and insert a catheter (a thin, flexible tube) into a blood vessel. They often use a vessel in the groin. The replacement valve attaches to the catheter. The physicians replace your faulty valve with this new one.
