I hope this posting could answer some of your questions on bypass surgery.
The Coronary arteries (CA) supply blood, oxygen & nutrients to the heart/cardiac muscles. It extends over the surface of the heart & branches into smaller capillaries.
CA can become blocked due to a buildup of fatty deposits called plaques on the inner wall of these arteries (a condition known as atherosclerosis). This reduce the flow of blood causing cardiac muscles receiving less blood which can lead to coronary artery disease (CAD).
Partially blocked CA (can reduce blood flow) causing chest pain (angina). A total/complete blockage of CA (can stop blood flow) causing a heart attack (myocardial infarction).
Various drugs can be used to treat CAD. Sometime, heart patients might need to undergo surgery to restore & improve blood flow. What are the available options?
Option 1:
Coronary bypass surgery/Coronary artery bypass surgery/Coronary artery bypass graft.
This is normally used to treat patients with multiple narrowed/blocked coronary arteries. By using blood vessels taken from another part of the body (either artery from the chest or a vein from the leg), a heart surgeon creates a graft to bypass the narrowed/blocked arteries. This allow blood to flow around the narrowed/blocked artery.
Most conventional bypass surgery requires open-heart surgery which means the surgeon will cut open the sternum (ribcage) in order to gain access to the heart.
Minimal invasive bypass surgery such as keyhole heart surgery maybe used when only 1 or 2 coronary arteries need a bypass and they are located around the front of the heart. A heart surgeon will make a 3- to 5-inch-long incision (cut) in the left part of the chest between the ribs to allow the surgeon to reach the heart for grafting .
Option 2: Angioplasty & stent placement
