About Dr. Naresh Trehan

Dr. Naresh Trehan is widely regarded as one of the most accomplished cardiovascular and cardiothoracic surgeons of his generation. With more than four decades of clinical practice spanning India and the United States, he has performed over 48,000 cardiac surgeries and has consistently ranked among the best heart surgeons in Asia.

Born and educated in India, Dr. Trehan completed his advanced surgical training at New York University Medical Center, where he served as a faculty member and refined techniques in minimally invasive heart surgery that were, at the time, adopted by very few surgeons globally. He returned to India in 1988 with a mission to bring world-class cardiac care to patients who lacked access to it.

Dr. Trehan is the founder and chairman of Medanta – The Medicity, a 1,250-bed multi-specialty hospital in Gurgaon that is consistently rated among the top hospitals in Asia. His philosophy is simple: every patient deserves the same standard of care, regardless of geography or socio-economic background.

He is a recipient of India's prestigious Padma Bhushan award and has been recognised by numerous national and international bodies for his contributions to cardiovascular medicine. Patients travel from over 60 countries to seek his expertise, particularly for complex valve reconstructions, off-pump bypass surgeries, and high-risk re-do cardiac operations.
