CORONARY BYPASS SURGERY Meaning and
Definition
-
Coronary bypass surgery is a medical procedure designed to bypass or circumvent clogged or narrowed coronary arteries, which supply blood to the heart muscle. It is a common surgical intervention used to improve blood flow to the heart and reduce symptoms of coronary artery disease (CAD).
During the procedure, a surgeon creates alternate pathways for blood to travel around the blocked or narrowed sections of the coronary arteries, using blood vessels harvested from other parts of the body. These newly grafted blood vessels allow blood to bypass the restricted or blocked arteries, ensuring a sufficient blood supply to the heart muscle.
Coronary bypass surgery is typically recommended for individuals with severe coronary artery disease that cannot be treated effectively with medication or other less invasive procedures like angioplasty. It is often performed when patients experience persistent chest pain (angina) or have a high risk of a heart attack.
The surgery is usually performed under general anesthesia and involves making an incision in the chest to access the heart. The surgeon then sews one end of the graft blood vessel to the aorta (the main artery exiting the heart) and the other end below the area of the blockage or narrowing in the coronary artery. This reroutes the blood flow, bypassing the affected area and restoring adequate blood supply to the heart muscle.
Coronary bypass surgery is a major surgical procedure that carries certain risks, including infection, bleeding, blood clots, and damage to the heart or blood vessels. However, it has been proven to be an effective treatment for many patients in improving their quality of life and reducing the risk of heart-related complications.
