Coronary Artery Bypass Surgery


Coronary Artery disease (CAD), sometimes called coronary heart disease (CHD), is a condition in which plaque, made up of fat, cholesterol, calcium, and other elements in the blood, build up inside the arterial walls of the heart. This is known as atherosclerosis (or hardening of the arteries) and is accelerated by smoking, fatty diets, diabetes, and age. Over time, if not removed, plaque can completely clog arteries restricting necessary blood and oxygen flow to the heart which can cause angina (chest pain) or allow blood clots to form that may lead to a heart attack.

Coronary artery bypass graft (CABG)

Coronary artery bypass grafting (CABG), sometimes referred to simply as heart bypass surgery, is a surgical procedure performed at New York Methodist and used to re-open narrowed or blocked heart arteries. People with severe coronary artery disease (CAD) are candidates for CABG, particularly if lifestyle changes and/or medications have not helped to restore proper function to the heart.

The operation involves taking a healthy vein or artery from elsewhere in the body and grafting it to the diseased artery. The new vein or artery is then used to bypass the blocked section of the artery allowing oxygen-rich blood to flow once again directly to the heart. There are several types of CABG surgery. NYM's expert cardiac surgeons can advise which procedure is best for each patient.

  • Traditional, or "on-pump," CABG is the most common procedure. It involves opening the chest to expose the heart which is then temporarily stopped from beating while the patient is attached to a cardiopulmonary bypass machine (or heart-lung pump) which circulates purified blood and oxygen through the rest of the body during the operation. This allows the surgical team to perform the bypass on a non-beating heart thereby increasing the stability of the operating field.
  • Off-pump CABG is very similar to traditional CABG; however, the heart-lung machine is not used and the heart continues to beat throughout the procedure. By not stopping the heart or using the heart-lung machine, recovery time and the incidence of some complications may be reduced. At New York Methodist, we also perform off-pump CABG using robot-assisted technology. Robotic surgery provides patients the benefits of a shorter hospital stay and a faster recovery.
  • New York Methodist also offers  minimally invasive direct CAB (or MIDCAB). With this approach, a small incision is created between two ribs on the left side of the chest. Through this small opening, the surgeon will usually create one bypass.
  • NYM is very proud to offer an innovative approach, called  radial artery grafting, which has been shown to offer significantly improved long-term outcomes. Instead of using a segment of a vein in the leg for bypassing a blocked artery in multiple bypass surgery, this advanced technique uses an artery from the arm, called the radial artery. This can reduce the risk by half that a patient experiences another blockage leading to closure of the bypass graft.
