In India, Doctor Devy Shetty founded Narayana Health, a chain of charitable and profitable hospitals, world-renowned for their expertise in cardiac surgery.


One man: Devy Shetty

Devy Shetty was born in 1953 in Kinnigoli, a small town of 16,000 residents located on the coast of India. In 1967, Doctor Christiaan Barnard successfully completed, with his team, the first heart transplant in South Africa. This extraordinary turning point in the history of medicine also marked the moment when Devy decided to become a cardiac surgeon. He completed the first part of his studies in Great Britain then returned to India where, in 1992, he completed the country’s very first heart transplant on an infant, who was only 9 days old.


One vision: quality care for all

But Devy Shetty didn’t stop at practicing heart surgery. A dedicated humanitarian, he was profoundly moved by Mother Teresa, whose heart he operated on after she had a heart attack in Calcutta. Inspired by Mother Teresa, he embarked on a new mission: to invent a medicine capable of providing quality care at a reduced cost.

How? By applying economies of scale to cardiac surgery. This was an incredibly iconoclastic and innovative vision. And it was met with initial skepticism.



One concept: economy of scale

Nicknamed “the Henry Ford of cardiac surgery” by the Wall Street Journal, Shetty was unstoppable in his mission…. And all alone. In 2001, he founded his first hospital on the outskirts of Bangalore with the goal of dividing the cost of cardiac surgery in half within 5 to 10 years. And it worked. By implementing strict efficiencies, with surgeons appearing only when the patient is ready for surgery, and precision ‘assembly line’ protocols practiced across the medical staff, the hospital was able to carry out 30 operations a day. The end result? More patients treated, more affordably!

And to date, Shetty has operated on more than 15,000 people…



Narayana Health has established 57 charitable hospitals and generates a profit. Patient fees are based on income: essentially, patients pay what they can. The hospitals have been such a success that many countries are looking to the Naravana Health model for inspiration – and best practices – that can help them change and improve their healthcare systems. Naravana Health offers the world hope for a more affordable, better-performing and humanitarian medical system.
