Heart bypass surgery - series

Normal anatomy

The heart muscle is supplied blood through the coronary arteries. The left coronary artery supplies blood to the left ventricle. The right coronary artery supplies blood to the right ventricle.

Normal anatomy

Indications

Coronary artery bypass grafting (CABG) or heart bypass surgery is recommended when one or more coronary arteries are seriously blocked and blood supply to the heart muscle is insufficient. Several tests are done to identify the cause of the chest pain (angina), such as blood tests and x-ray studies (angiograms).

Indications

Procedure, part 1

Although the heart itself is not "opened", the heart-lung bypass machine is used to re-route the blood from the heart while the surgery is being done to provide adequate circulation to the brain and other vital organs.

Procedure, part 1

Procedure, part 2

Coronary bypass surgery is an open heart surgery (the chest is opened, but not the heart itself). It is done through an opening through the breast bone. While one surgeon is working on the chest, another surgeon works on taking a length of vein (saphenous vein) for the bypass through a long incision along the inside of the lower leg. The vein is sewn in above and below the blockage in the coronary artery. Alternatively, an artery from the interior aspect of the chest wall (internal mammary artery), or the arm (radial artery) is used.

Procedure, part 2

Procedure, part 3

In many cases, more than one coronary artery must be bypassed, and both the internal mammary and radial arteries and the saphenous vein are used to perform the bypasses.

Procedure, part 3

Aftercare

After the operation, the patient will spend 7 to 10 days in the hospital, the first 1 to 3 days in an intensive-care unit (ICU). Chest tubes will be in place for the first 2 to 3 days to drain any residual blood and fluid from around the heart. Heart functions will be monitored. The full benefits from the operation may not be ascertained until 3 to 6 months after surgery. Sexual activity may be resumed 3 to 4 weeks after surgery. All activities that do not cause fatigue are permitted, but the patient must not strain the healing chest bone (sternum).
