Following the tremendous success of India’s first National MICS Workshop at HCG Hospital Bhavnagar, many patients and their families have been asking about the different types of bypass surgeries available today. As the best cardiac surgeon and best cardiothoracic surgeon in India, Dr. Brajmohan Singh believes in educating patients about their treatment options to make informed decisions about their heart health.
One of the most common questions patients ask is: “What’s the difference between SIMA and BIMA bypass surgery, and which one is right for me?” Let’s explore these advanced surgical techniques and understand why Dr. Brajmohan Singh, recognized as the best BIMA bypass surgeon, recommends specific approaches for different patients.
Understanding SIMA: Single Internal Mammary Artery Bypass
SIMA stands for Single Internal Mammary Artery – a bypass technique that uses either the Left Internal Mammary Artery (LIMA) or Right Internal Mammary Artery (RIMA), but not both.
Key Features of SIMA Surgery:
● Uses one internal mammary artery (typically LIMA)
● Often combined with vein grafts for multiple blockages
● Less complex surgical procedure
● Shorter operative time
● Good long-term results for single-vessel disease
When is SIMA Recommended?
As the best cardiovascular and thoracic surgeon and best minimally invasive cardiac surgeon in
India, Dr. Singh typically recommends SIMA for patients with:
● Single-vessel coronary artery disease
● Limited life expectancy due to other medical conditions ● High surgical risk patients
● Those unsuitable for bilateral arterial harvesting
Understanding BIMA: Bilateral Internal Mammary Artery Bypass
BIMA stands for Bilateral Internal Mammary Artery – an advanced technique using both the left (LIMA) and right (RIMA) internal mammary arteries for bypass surgery.
Key Features of BIMA Surgery:
● Uses both internal mammary arteries
● Can be configured in Y-graft pattern (LIMA-RIMA-Y)
● Provides complete arterial revascularization
● Longer operative time but superior long-term outcomes ● Requires advanced surgical expertise
When is BIMA Recommended?
Dr. Singh, the best BIMA bypass surgeon in India, recommends BIMA for:
● All patients (no age limit)
● Diabetic patients
● Multiple-vessel coronary artery disease
● Patients seeking long-term graft patency
● Active individuals who want to avoid repeat surgeries
SIMA vs BIMA: A Detailed Comparison
| Aspect | SIMA (Single IMA) | BIMA (Bilateral IMA) |
| Graft Durability | 15-20 years | 20-25+ years |
| Surgical Complexity | Moderate | High |
| Operative Time | 3-4 hours | 4-6 hours |
| Recovery Time | Standard | Slightly longer |
| Long-term Survival | Good | Excellent |
| Repeat Surgery Risk | Higher | Lower |
| Ideal Candidates | Elderly, high-risk | Young, diabetic |
As the best cardiothoracic surgeon in India, Dr. Brajmohan Singh explains the advantages of
BIMA:
Superior Long-term Outcomes:
● Better Survival Rates: Studies show BIMA patients have significantly better 10-year and 20-year survival rates
● Lower Repeat Surgery Risk: BIMA grafts rarely require reoperation
● Complete Arterial Revascularization: No dependence on vein grafts that may fail over time
Specific Benefits for Different Patient Groups:
● Diabetic Patients: BIMA shows exceptional results in diabetic patients
● Young Patients: Provides decades of graft patency
● Active Lifestyle: Supports return to full physical activity
Dr. Singh’s Advanced LIMA-RIMA-Y Technique
Dr. Brajmohan Singh is renowned as the best LIMA RIMA Y surgeon, best TAG (Total Arterial Grafting) surgeon, and best cardiovascular surgeon in India. His specialized Y-graft configuration offers:
Technical Advantages:
● RIMA connected to LIMA in Y-configuration
● Complete arterial revascularization
● Optimal blood flow distribution
● Reduced risk of graft failure
Patient Benefits:
● Maximum graft longevity
● Lower risk of complications
● Excellent long-term cardiac function
● Reduced need for future interventions
Combining BIMA with MICS: The Gold Standard
As the best minimally invasive cardiac surgeon in india Dr. Singh often combines BIMA with minimally invasive techniques:
● Faster Recovery: Smaller incisions mean quicker healing
● Less Pain: Minimal tissue trauma
● Better Cosmetics: Virtually invisible scars
● Same Excellent Results: All the benefits of BIMA with MICS advantages
Making the Right Choice: SIMA or BIMA?
The decision between SIMA and BIMA depends on several factors that Dr. Singh, the best cardiovascular and thoracic surgeon in India, carefully evaluates:
Patient Factors:
● Age: BIMA is preferred for all patients regardless of age.
● Life Expectancy: Long life expectancy favours BIMA
● Diabetes Status: Diabetics benefit significantly from BIMA
● Coronary Anatomy: Number and location of blockages
● Overall Health: Surgical risk assessment
Technical Considerations:
● Surgeon Expertise: BIMA requires advanced surgical skills
● Hospital Infrastructure: Capability for complex procedures
● Patient Preferences: Understanding long-term vs. short-term considerations
Success Stories: Real Patient Outcomes
BIMA Success Case:
“I underwent LIMA-RIMA-Y surgery by Dr. Brajmohan Singh three years ago. At 55 and diabetic, Dr. Singh recommended BIMA for long-term benefits. Today, I’m completely symptom-free and lead an active life. My recent angiogram shows perfect graft function. Dr. Singh truly is the best BIMA bypass surgeon in India.” – Patient from Rajkot
SIMA Success Case:
“Being 75 years old with multiple health issues, Dr. Singh recommended LIMA surgery for my single-vessel disease. The procedure was smooth, recovery was quick, and I’m doing excellently. His expertise as the best cardiac surgeon in India gave me confidence throughout.” – Patient from Ahmedabad
