TAVI stands for transcatheter aortic valve implantation. This is a new procedure for replacing a faulty aortic valve in the heart. The aortic valve opens to permit blood to flow from the left ventricle into the aorta, which carries blood to the rest of the body. The valve closes between heartbeats to prevent blood from flowing back into the ventricle If the aortic valve does not open or close properly, the heart has to work harder to pump blood into the aorta. This can cause symptoms such as chest pain and shortness of breath and may ultimately lead to heart failure. Treatment of a faulty aortic valve generally requires open heart surgery. The surgeon cuts through the chest bone, stops the heart, removes the faulty valve, and replaces it with a mechanical or biological valve. With TAVI, an artificial valve is implanted via a catheter, which is navigated to the heart through an artery via an incision in the skin. The femoral artery in the leg is most often used, but others such as the subclavian artery beneath the collar bone may also be used. The replacement valve is placed inside the existing valve. The procedure is performed on the beating heart, without the need for a heart lung machine. Both procedure and recovery time are significantly reduced.
