All you need to know about Open Heart Surgery

 

Open heart surgery is a major surgery, which takes place to rectify a damage to the heart. During this surgery, the doctor will cut open the chest and the operation is performed on the muscles, valves or arteries of the heart. The most common open-heart surgery is the coronary artery bypass surgery.

In this operation, a healthy artery or vein is attached to the blocked coronary artery. Hence, the attached artery is allowed to go around the blocked coronary artery, supplying fresh blood to the heart. This surgery is also sometimes known as Traditional Heart Surgery.

 

An open-heart surgery becomes a necessity when the coronary arteries become narrow. This happens because of a heart disease and the narrow arteries can lead to a heart attack. The artery that is attached is borrowed from someplace else, usually the chest or the leg. Open-heart surgery is also performed to repair or replace the faulty/damaged valves. The valves that are present in the heart are responsible to stop the blood from flowing back into the parts of the heart once it is pumped out.

 

The Open-heart surgery can also treat an aneurysm. In this condition, a bulge occurs in the main artery.
