Commonly known as bypass surgery, this is a procedure done to restore blood flow in a narrow or blocked artery. The procedure is an open heart surgery that requires a large incision to be made to access the chest cavity. The surgeon takes out a blood vessel from one part of your body and uses to divert blood flow away from the blocked coronary artery in order to restore the blood flow. A blocked or narrowed artery severely increases the strain on the heart and will eventually result in heart failure. Consult with our top cardiologists in Mangalore to know more.
