Aortic valve replacement or aortic valve replacement is an open heart surgery procedure that is performed to treat patients with aortic valve disorders. This procedure aims to replace the aortic valve that has failed or is malfunctioning. Damaged aortic valves are replaced with artificial aortic valves, from synthetic materials or animal body tissues. The aorta is the largest arterial blood vessel that is directly connected to the heart, and is tasked with flowing oxygen-rich blood from the heart to the entire body. Before entering the aorta, blood from the left ventricle of the heart passes through the aortic valve, which is one of the four valves that the heart has. Aortic valve that is not functioning normally will cause disruption of blood flow, so the heart will work extra to meet the needs of blood supply throughout the body.
