Triple coronary bypass surgery: the details of the operation

Triple coronary bypass surgery is surgery to restore blood flow to the coronary artery when it becomes blocked. In particular, it helps prevent heart attacks. Risks, convalescence, life expectancy, complications: all you need to know about this operation.


Coronary artery bypass surgery is a heart surgery procedure. This consists of creating a “bridge” in order to bypass one or more blocked parts of the artery, and restore normal blood flow to the heart. The coronary arteries are divided into many branches, which is why bypass surgery can be single or multiple depending on the number of lesions to be treated with the help of open heart surgical instrument set.


Coronary bypass surgery is recommended by the cardiologist to treat coronary artery stenosis (narrowing of the coronary arteries). These narrowing occur when the arteries are blocked by fatty deposits, the main risk factors of which are excess cholesterol, smoking, diabetes and obesity. Coronary bypass surgery also helps prevent heart attacks and increase life expectancy. This procedure is offered when the lesions of the arteries cannot be treated with medication, and when it is not possible to have angioplasty (dilation of the arteries) or the placement of a stent (device aimed at widening the artery).

Special features of triple coronary bypass surgery

The fact of receiving a triple coronary bypass surgery has no relation to the severity of the condition. It is indicated in the event of multiple strictures to be circumvented: three in the case of triple bypass. Note that coronary bypass surgery can also be single, double, quadruple, or even quintuple.


To perform coronary bypass surgery, the surgeon removes the mammary arteries (located behind the sternum), the saphenous veins (in the leg) or the radial artery: he uses them to create one or more deviations from the aorta artery to the healthy part of the coronary artery “, explains Pr. Francis Junthier, thoracic and cardiovascular surgeon.

The use of arteries is preferred because of their greater durability. The intervention requires an opening in the sternum in order to access the heart and arteries Once the grafts are removed, the surgeon establishes an extracorporeal circulation (ECC) using a machine to temporarily replace the work of the heart and lungs, and then proceeds to bypass surgery by implanting the vein or artery taken between the aorta and the part located downstream of the obstruction.

The operation is performed under general anesthesia and depending on the number of bypass operations to be performed, usually lasts between 2 and 5 hours.

Operative suites

After coronary bypass surgery, the patient remains between 24 and 72 hours in intensive care for close monitoring. Hospitalization of one to two weeks is necessary.

Convalescence: 1 to 2 months

It is on average one to two months. Follow-up should be set up with the cardiologist, with regular visits once or twice a year. To avoid new strictures, medical treatment will be put in place (antiplatelet agents, beta blockers, converting enzyme inhibitors and cholesterol lowering drugs). At the same time, it is essential to adapt your lifestyle: practice of a physical activity (walking or cycling), healthy and balanced diet, weight loss if necessary and stopping smoking.
