What is heart bypass surgery?

Bypass surgery refers to a surgical procedure that helps in diverting the blood flow around a blocked or partially blocked artery of the heart. It is done to create a new pathway to the heart and improving the flow of blood to the heart muscle. During this surgery, a healthy, well-functioning blood vessel is taken from the arm, chest or leg and then connected to the other arteries in the heart so that the blood can bypass the blocked or the diseased area.

Problems such as shortness of breath and chest pain, due to poor flow of blood tend to improve after a bypass surgery. It may also improve the heart function and reduce the risk of a heart disease. Heart bypass surgery, or coronary artery bypass graft (CABG) surgery, is utilized to improve blood flow to your heart. A surgeon uses blood vessels taken from another area of your body to bypass the damaged arteries. This surgery is done when coronary arteries become blocked or damaged. These courses supply your heart with oxygenated blood. If these arteries are blocked or blood flow is restricted, the heart doesn’t work properly thus it can prompt heart failure.
