Which surgical procedure involves connecting new vessels to the heart muscle?

The surgical procedure that involves connecting new vessels to the heart muscle is the coronary artery bypass graft. This procedure is primarily performed to restore blood flow to the heart muscle when the coronary arteries are blocked or narrowed due to conditions such as atherosclerosis. During the bypass graft surgery, surgeons take a healthy blood vessel, often from the leg or the chest, and create a new pathway for blood to flow around the blocked segment of the coronary artery. This new connection helps to ensure that the heart muscle receives adequate oxygen and nutrients, thereby improving heart function and reducing the risk of heart-related complications.

Heart valve replacement, aortic valve repair, and myocardial ablation serve different purposes, such as addressing valve dysfunction or treating arrhythmias, but they do not specifically involve the creation of new blood vessels to bypass obstructions in the coronary arteries.
