Overview
Dr. Ayubi offers expert cardiac surgery in Kolkata for a wide range of heart conditions. With extensive experience in both conventional and minimally invasive techniques, including MICS CABG and MICS valve replacements, he ensures optimal outcomes even in complex cases.
Common Causes
CABG is most often needed for atherosclerotic coronary artery disease driven by diabetes, hypertension, smoking, high cholesterol, obesity, and genetic predisposition. Plaque buildup reduces oxygen supply to the heart and can lead to angina, heart attack, or heart-function decline.
Signs & Symptoms
- Exertional or rest angina
- Shortness of breath
- Fatigue and reduced walking distance
- Chest pressure radiating to arm or jaw
- Symptoms after failed or incomplete stenting
- Silent ischemia in some diabetic patients
When to Consult a Specialist
- Severe multivessel or left main disease
- Ongoing angina despite optimal medical therapy
- Diabetes with complex coronary anatomy
- Reduced heart function with significant blockages
- Unsuitable anatomy for stenting alone
Diagnosis
- History, examination, and risk-factor review
- ECG, echo, and functional testing
- Coronary angiography for vessel mapping
- Heart-team discussion of CABG versus PCI
- Pre-operative fitness and comorbidity assessment
Treatment Options
- Medical therapy and lifestyle modification
- Percutaneous coronary intervention for selected lesions
- On-pump or off-pump CABG based on patient need
- Arterial and venous conduit strategies for durability
- Cardiac rehabilitation and lifelong prevention
Procedure Information
CABG uses grafts from the patient’s own arteries or veins to bypass blocked coronary segments. The operative plan aims for complete revascularization, careful conduit selection, and stable recovery, with technique adapted to anatomy, heart function, and overall risk.
Benefits & Possible Risks
Benefits
- Relief from angina and improved stamina
- Better long-term outcomes in appropriate candidates
- Protection of heart muscle from ongoing ischemia
- Effective option for complex multivessel disease
- Clear pathway from surgery into rehabilitation
Possible Risks
Potential complications include bleeding, infection, arrhythmia, stroke, kidney stress, graft failure, or prolonged recovery. Risk is influenced by age, diabetes, heart function, lung disease, and urgency of surgery, and is explained in detail before consent.
Recovery & Follow-Up
- ICU monitoring followed by ward recovery
- Breathing exercises and early walking
- Medications for graft and heart protection
- Sternal precautions and wound care guidance
- Structured cardiac rehabilitation after discharge
