The procedure for Conventional CABG is different from CABG. In this Heart Bypass Surgery, the doctors make use of connecting grafts to cure blockages in the arteries. This process involves the use of cardiopulmonary bypass; it is possible by using a heart-lung machine. 

For initiation of this Bypass Surgery Procedure, the essential requirement is to stop the functioning of the heart. The surgeons perform the surgery on a still heart. The heart-lung machine works like an artificial heart. It eliminates carbon dioxide from the blood and supplies the blood full of oxygen.

Before beginning with the treatment, the surgeon first stabilises the particular portion of the heart. The successful bypass of a blocked artery requires a highly controlled environment throughout the surgical procedure.

  • Minimum Invasive Cardiac Surgery:

It is an advanced technique to perform Heart Bypass Surgery. Unlike other types of Bypass Surgery Procedure, it does not involve any cutting or splitting of the sternum or breastbone.

The main focus of CABG surgery is the placement of bi-ventricular pacemaker on the surface of the left ventricle while the minimally invasive surgery aims at atrial fibrillation.

The scientists are continuously working in the field of research to get technological advancements and obtain better surgical results. Presently, the main focus is on robotic surgical advancements.
