Coronary Artery Bypass Grafting (CABG) is one of the most common and effective surgical procedures used to treat coronary artery disease (CAD). In India, CABG surgery has become widely accessible, with numerous hospitals offering world-class treatment at a fraction of the cost compared to Western countries. The country is home to some of the most skilled cardiothoracic surgeons and state-of-the-art medical facilities, making it a preferred destination for both domestic and international patients seeking cardiac care.
Understanding Coronary Artery Disease (CAD)
Coronary Artery Disease occurs when the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked due to the buildup of plaque. This plaque is composed of fat, cholesterol, and other substances that accumulate on the inner walls of the arteries. The narrowing or blockage restricts blood flow to the heart, leading to chest pain (angina), shortness of breath, or even a heart attack.
What is Coronary Artery Bypass Grafting (CABG)?
Coronary Artery Bypass Grafting (CABG) is a surgical procedure that improves blood flow to the heart by creating new pathways (bypasses) around the blocked or narrowed arteries. The surgery involves taking a healthy blood vessel from another part of the body, such as the leg, arm, or chest, and grafting it onto the coronary artery. This new blood vessel bypasses the blocked section of the artery, allowing blood to flow more freely to the heart muscle.
Indications for CABG Surgery
CABG surgery is recommended for patients with severe coronary artery disease who have not responded well to other treatments, such as medication or lifestyle changes. It is particularly indicated in the following situations:
- Multiple Blocked Arteries: When several coronary arteries are blocked or narrowed, CABG is often the best treatment option.
- Left Main Coronary Artery Disease: If the left main coronary artery, which supplies a significant portion of blood to the heart, is severely narrowed or blocked, CABG is typically recommended.
- Failed Angioplasty or Stenting: If previous attempts to open blocked arteries with angioplasty or stenting have failed, CABG may be necessary.
- Severe Symptoms: Patients with severe angina, shortness of breath, or other symptoms that significantly affect their quality of life may benefit from CABG surgery.
The CABG Procedure
CABG surgery is typically performed under general anesthesia and can take anywhere from three to six hours, depending on the complexity of the case. The procedure can be done using different techniques, including traditional open-heart surgery, off-pump CABG (also known as beating-heart surgery), or minimally invasive CABG.
- Traditional CABG: In traditional CABG, the surgeon makes a large incision in the chest to access the heart. The heart is temporarily stopped, and a heart-lung machine is used to circulate blood and oxygen during the surgery. The surgeon then grafts the healthy blood vessels onto the coronary arteries to bypass the blockages.
- Off-Pump CABG: Also known as beating-heart surgery, this technique does not require stopping the heart. The surgeon operates on the heart while it is still beating, using specialized equipment to stabilize the area being operated on. Off-pump CABG can reduce the risk of complications associated with the heart-lung machine.
- Minimally Invasive CABG: In this technique, the surgeon makes smaller incisions in the chest, avoiding the need for a large incision and reducing recovery time. Minimally invasive CABG is usually suitable for patients with less severe disease and fewer blockages.
Post-Surgery Recovery
Recovery from CABG surgery can vary depending on the patient’s overall health, the complexity of the surgery, and the type of procedure performed. Typically, patients spend a few days in the hospital after the surgery, followed by several weeks of recovery at home.
- Hospital Stay: Patients are usually monitored in the Intensive Care Unit (ICU) for the first 24-48 hours after surgery. Once stable, they are moved to a regular hospital room for continued recovery.
- Home Recovery: After being discharged from the hospital, patients are advised to rest, avoid strenuous activities, and gradually increase physical activity as they recover. Follow-up appointments with the surgeon are crucial to monitor progress and ensure proper healing.
- Lifestyle Changes: To prevent further heart problems, patients are encouraged to adopt a heart-healthy lifestyle, including a balanced diet, regular exercise, quitting smoking, and managing stress.
