Ventricular Restoration is a progressive treatment for congestive heart failure, which often occurs with people who have previously had heart attacks. Following a heart attack, the patient's heart often develops scarring, or an aneurysm (an unhealthy, weakened bulge in the heart wall). Since the left ventricle is responsible for pumping blood to the rest of the body, either of these conditions hamper the heart's ability to pump normally, which can lead to congestive heart failure. Ventricular restoration, then, aims to restore the heart to its healthy size and shape, therefore improving function. The procedure is often performed in conjunction with coronary artery bypass grafting, to ensure proper blood supply to the heart. Some patients may also have valve repair during the same operation.
