If you have severe coronary artery disease and plaque build-up in your arteries that is blocking the flow of oxygen-rich blood to your heart, we may need to perform coronary artery bypass graft surgery (CABG), also called bypass surgery. This open-heart procedure involves rerouting the blood flow to the heart by surgically attaching an additional blood flow vessel to bypass a blocked or extremely narrowed coronary artery.
The New York State Department of Health has recognized The Mount Sinai Hospital as one of the best at performing this procedure in the New York metropolitan area. We have particular expertise with reoperative procedures and with combination bypass and valve repair/replacement procedures, which can carry a higher-than-usual risk. The Society of Thoracic Surgeons has developed a comprehensive rating system for the quality of Coronary Artery bypass surgery and for the quality of Aortic Valve Replacement Surgery among hospitals across the country. Approximately 3% of hospitals received the “3 star” rating in both CAB and AVR, which denotes the highest category of quality. In the current analysis of national data covering the period from January 1, 2016 through December 31, 2016, both the Coronary Artery Bypass surgery as well as the Aortic Valve Replacement surgery performance of The Mount Sinai Hospital was found to lie in this highest quality tier, thereby receiving an STS 3-star rating.
To perform a CABG, we reroute the blood flow using a vein from your leg, an existing artery in your chest wall, or an artery from your forearm (radial artery). We take one end of this blood vessel and connect it to the aorta where the coronary artery originates and the other end to the affected coronary artery, below the blockage area. This creates an alternate route for blood flow.
The surgery takes between two to six hours to perform and you typically remain in the hospital for three to five days after.
