Overview
Coronary Artery Bypass Grafting (CABG) is a major surgery that helps people with severe coronary artery disease improve blood flow to their hearts. When the coronary arteries become very narrow or blocked, CABG creates a new route for blood to reach the heart muscle. This procedure involves using a healthy blood vessel, or graft, harvested from the leg, chest, or arm, and then threading it around the obstructed artery. The number of arteries bypassed during coronary artery bypass grafting (CABG) depends on the extent of the disease. While open-heart surgery is the standard approach, less invasive techniques are sometimes employed.
Why it’s Done?
The surgery is performed when medications or angioplasty are insufficient to address severe or widespread coronary artery blockages. Coronary artery bypass grafting (CABG) is often recommended for people with multiple blocked arteries, those with issues in the left main coronary artery, or those with reduced heart function. The goal is to get the blood flowing, ease any chest pain, lower the chances of a heart attack, and, in the end, improve how long a person lives and how well they live.
What to expect?
Prior to the operation, a comprehensive assessment is conducted, encompassing blood work, an ECG, an echocardiogram, and a coronary angiogram. The patient is placed under general anesthesia for the duration of the procedure. The surgeon cuts into the chest to get to the heart. A heart-lung machine usually takes over for the heart and lungs while the grafts are being attached. The surgeon carefully attaches the grafts, bypassing the clogged arteries to restore blood flow to the heart. The operation typically takes anywhere from three to six hours. Following the surgery, patients are transferred to the intensive care unit for close monitoring. Initial recovery involves assistance with breathing, medication management, and gradual increases in mobility. Most of the time, people stay in the hospital for about a week.
Outlook & Recovery.
It could take weeks or even months for recovery, and activities will slowly return to normal. Cardiac rehabilitation is a good way to strengthen your heart and body. CABG helps patients live longer and feel better for a long time.
