BIMA refers to using both the left and right internal mammary arteries during coronary artery bypass grafting. These arteries provide excellent blood flow and long-term patency, making them superior to vein grafts. BIMA is commonly used in advanced cardiac cases requiring durable and effective myocardial revascularization.
BIMA procedures are categorized into in-situ BIMA and composite or Y-graft BIMA techniques. In-situ BIMA uses arteries in their natural position, while composite grafting combines arteries for extensive coverage. The choice depends on coronary anatomy, patient health, and surgical expertise.
BIMA is recommended when patients have severe coronary artery blockages, multi-vessel disease, diabetes, or long life expectancy. These factors demand durable grafting solutions. Surgeons choose BIMA to ensure sustained blood supply and reduce repeat cardiac interventions.
Symptoms include persistent chest pain, shortness of breath, fatigue, reduced exercise tolerance, and recurrent angina despite medication. These signs indicate advanced coronary artery disease where traditional treatments may not suffice, making BIMA a suitable surgical option.
Diagnosis involves coronary angiography, stress testing, echocardiography, and cardiac CT scans. These tests assess artery blockages, heart function, and blood flow patterns. Based on results, cardiac surgeons determine if BIMA grafting offers the best long-term outcome.
Treatment includes advanced coronary artery bypass surgery using both internal mammary arteries. This approach improves graft longevity, lowers heart attack risk, and enhances survival. Post-surgery care involves cardiac rehabilitation, lifestyle changes, and regular follow-ups for optimal recovery.
Key signs that indicate the need for immediate medical evaluation include severe symptoms or sudden changes.
Persistent pain may signal severe coronary blockage requiring surgical intervention.
Indicates compromised heart blood flow needing advanced assessment.
Suggests failure of conservative treatment options.

Sandeep Nambiar Bilateral Internal Mammary Artery Bypass Surgery
BIMA bypass surgery uses both internal mammary arteries to bypass blocked coronary arteries. These arteries have excellent long-term patency, which helps improve heart function and reduces the chances of future blockages compared to traditional vein grafts.
Patients with multivessel coronary artery disease, good overall health, and controlled diabetes or blood pressure may be suitable. The final decision depends on age, chest anatomy, lifestyle, and surgeon expertise after detailed evaluation.
Yes, BIMA surgery is safely performed across India in experienced cardiac centers. With proper patient selection, infection control, and post-operative care, outcomes are highly successful and comparable to global standards.
BIMA offers better long-term graft survival, improved blood flow, reduced need for repeat surgeries, and enhanced life expectancy. It is especially beneficial for younger patients requiring durable heart bypass solutions.
Initial recovery usually takes 4–6 weeks. Full recovery, including return to normal activity, may take up to 3 months depending on age, overall health, and adherence to rehabilitation and medication plans.
