Transcatheter Aortic Valve Implantation, or TAVI for short, is performed to replace a faulty aortic valve in the heart. When the aortic valve doesn't work properly, the heart has to work harder to pump blood into the aorta, which pumps oxygenated blood to the rest of the body. Go inside the body to see how this surgery is performed.
