Best ASO Surgeons in India 2025 – GAF Healthcare

India's best surgeons for arterial switch operation. Fellowship-trained, 94–97% survival. GAF Healthcare matches your case to the right surgeon in 24 hours.

The arterial switch operation is not a procedure where any experienced cardiac surgeon will do. It is one of the most technically demanding operations in all of neonatal surgery — performed on a heart the size of a walnut, in a patient who may weigh under three kilograms, with a two-hour window of deep hypothermic circulatory arrest during which the entire procedure must be completed without error. The surgeon who transfers the coronary arteries — millimetre-wide vessels excised with a button of arterial wall and reimplanted into a new root — is the single most important variable in whether your child survives the operation and walks out of hospital with a functioning heart.

India's leading paediatric cardiac surgeons are not a compromise. Several of the country's most active ASO surgeons completed their fellowship training at Great Ormond Street Hospital in London, Boston Children's Hospital, and Toronto's Hospital for Sick Children — the same institutions whose published survival rates are cited as the global benchmark. They returned to India and built programmes that now perform more annual ASO cases than most of the institutions where they trained. Volume compounds expertise. At Narayana Health Bangalore alone, the paediatric cardiac surgery unit performs more neonatal cardiac operations per year than most entire national programmes in Europe.

GAF Healthcare works with paediatric cardiac surgeons at Narayana Health, AIIMS New Delhi, Fortis Escorts Heart Institute, Apollo Hospitals, and Medanta – The Medicity. When a family contacts us with their child's echocardiogram, we do not simply send the case to the nearest available surgeon. We review the coronary anatomy — the most critical variable in ASO outcomes — and match the case to the surgeon whose specific experience with that coronary pattern gives the best chance of a successful result. For families travelling thousands of kilometres with a critically ill newborn, that matching process is not a formality. It is the most important thing we do.
