The Bentall procedure is a surgery performed to correct defects of the aorta. The aorta is the largest artery that stems from the heart and branches into smaller arteries to distribute oxygenated blood to all parts of the body. It can be divided into the ascending aorta (part that rises from the heart), aortic arch (part that bends over the heart), descending thoracic aorta (part that moves down the chest region) and abdominal aorta (part that begins at the diaphragm). The procedure involves the replacement of the aortic root (base of the aorta) and valve (three flaps that ensure the one-way flow of blood from the heart to the aorta), and re-implantation of the coronary arteries (that branch out from the ascending aorta). The current and most common type of surgery is called the button Bentall surgery.
