In the bustling capital of Delhi, a young man named Daljeet Singh Gambhir set out on a path that would one day open blocked arteries and open new doors for Indian cardiology. He graduated from the prestigious Maulana Azad Medical College, completed his MD there, and then earned his DM in Cardiology. In 1985 he joined the Department of Cardiology at G.B. Pant Hospital as an Assistant Professor. By the age of forty-four he had already risen to full Professor—one of the youngest to hold that chair.

There he refined the art of non-surgical coronary intervention. Over the decades he performed more than fifteen thousand angioplasties, many of them complex multivessel procedures that once would have required open-heart surgery. In 2002 he achieved a landmark: in collaboration with Indian scientists he developed the Infinnium Paclitaxel-Eluting Stent—the first drug-eluting stent created in India and only the second in the world. When he presented the clinical data at the EuroPCR meeting in Paris in 2003, the international community sat up and took notice. India had entered the global map of interventional device innovation.

Later he moved to the Kailash Group of Hospitals as Group Director of Cardiology, continuing to train young cardiologists through live demonstrations both in India and abroad. Fellowships followed from the National Academy of Medical Sciences, the American College of Cardiology, the Society for Cardiovascular Angiography and Interventions, and many others.

One afternoon, after a particularly challenging left-main stenting, a patient clutched his hand and asked, “Doctor, will my heart really stay open now?”

Daljeet Singh smiled. “We have given the artery a new path. The rest depends on how carefully you walk it. But yes—your heart has been given another chance.”

In 2016 the President of India conferred upon him the Padma Shri for his distinguished contributions to medicine. Lifetime Achievement Awards from the Delhi Medical Association and the Cardiological Society of India, along with the Distinguished Physician Award from American cardiologists of Indian origin, followed in recognition of a lifetime spent widening the arteries of hope.

Today, as one of India’s foremost interventional cardiologists, Dr. Daljeet Singh Gambhir continues to innovate, teach and heal. From a determined student at Maulana Azad Medical College to the Padma Shri awardee who placed India on the world stage of drug-eluting stents, his journey remains a powerful testament to skill, research and the quiet determination to keep hearts beating longer.
