Coronary Artery Bypass Grafting (CABG) in Chennai | Advanced Heart Bypass Surgery by Dr. A. Mohammed Idhrees
Restoring optimal blood flow to the heart through advanced coronary bypass techniques.
Coronary Artery Bypass Surgery (CABG) in Chennai
Coronary Artery Bypass Grafting (CABG), commonly known as heart bypass surgery, is one of the most effective treatments for severe coronary artery disease. When the coronary arteries become narrowed or blocked due to plaque buildup, the heart muscle may not receive enough oxygen-rich blood, increasing the risk of chest pain (angina), heart attack, and heart failure. At HeartNarota, Dr. A. Mohammed Idhrees, Senior Cardiovascular and Thoracic Surgeon with over 18 years of experience, performs advanced CABG procedures using evidence-based surgical techniques, including conventional open-heart bypass surgery, off-pump CABG, minimally invasive CABG, and arterial grafting. Every treatment plan is individualized to restore healthy blood flow and support long-term heart health.
What is Coronary Artery Bypass Surgery?
Coronary Artery Bypass Grafting (CABG) is a surgical procedure that restores blood flow to the heart by creating a new pathway around blocked coronary arteries. Healthy blood vessels taken from the chest, arm, or leg are used as grafts to bypass the blocked artery, allowing oxygen-rich blood to reach the heart muscle. CABG is recommended for patients with severe coronary artery disease, multiple blocked arteries, left main coronary artery disease, or diabetes with complex coronary blockages
When is CABG Surgery Recommended?
- Multiple blocked coronary arteries
- Significant left main coronary artery disease
- Severe angina not relieved by medication
- Reduced blood flow to the heart
- Failed angioplasty or stent placement
- Diabetes with multivessel coronary artery disease
- Heart attack requiring surgical revascularization
Symptoms of Coronary Artery Disease
- Chest pain (angina)
- Shortness of breath
- Fatigue
- Pain in the arm, jaw, neck, or back
- Reduced exercise tolerance
- Irregular heartbeat
- Silent ischemia without symptoms
How Long Does Coronary Artery Bypass Surgery Take?
CABG surgery typically takes 3 to 6 hours, depending on the number of blockages and complexity (single, double, or triple bypass).
