Coronary Artery Bypass Grafting (CABG), also known as Coronary Artery Bypass Surgery & popularly Heart Bypass or Bypass Surgery, is a surgical procedure to restore normal blood flow to an obstructed coronary artery. Obstructed coronary artery means when the coronary arteries are narrowed or occluded, most commonly by atherosclerotic deposits of fibrous and fatty tissue.

B) Atypical :
Arterial Grafting :
The left internal thoracic artery (internal mammary artery) is diverted to the left anterior descending branch of the left coronary artery.
Venous Grafting :
In the other, a great saphenous vein is removed from a leg; one end is attached to the aorta or one of its major branches, and the other end is attached to the obstructed artery immediately after the obstruction to restore blood flow.
A) Regularly performing Off-pump CABG : A coronary artery bypass graft (CABG) is done without putting the patient on the heart-lung machine. Off-pump CABG permits surgery on multiple vessels within the heart by mechanically stabilizing it. Off-pump surgery is minimally invasive, as compared to surgery on the heart-lung machine.
B) Desun Performs minimally invasive cardiac surgery : Most cardiac operations today are performed through a sternotomy, which involves splitting the entire breastbone. Minimally invasive cardiac surgery encompasses a variety of operations performed through incisions that are substantially smaller and less traumatic than the standard sternotomy. Minimally invasive incisions measure about 3 to 4 inches compared to 8 to 10 sternotomy incisions. Specialized handheld and robotic instruments are used to project the dexterity of the surgeon’s hands through these small incisions in performing the operations.

This 8 to 10 inch incision splits the
This 4 to 5 inch incision just splits the upper
third of the breastbone.
This 3 to 4 inch incision is made between the
ribs whereby no bone is cut.
Robotic instruments are passed through several
1/2 inch incisions between the ribs.
Minimally invasive surgery confers many advantages over standard approaches derived largely from the reduced trauma to the chest wall tissues. The benefits of minimally invasive cardiac surgery include:
