Al Jazeera first brought you the story of Narayana Health in 2012 - a hospital on the outskirts of Bangalore, India's third largest city.
Narayana is a place where both rich and poor Indians come to seek affordable medical care, something almost non-existent in a country of over a billion people.
When we first met the hospital's founder, Dr Devi Shetty, he was experimenting with the way doctors are trained in India.
Six fresh medical school graduates were chosen to be groomed as cardiac surgeons, bypassing the traditional three years of general surgery normally required before specialisation.
Two years on, this is Al Jazeera's web exclusive looks at how far Dr Shetty's experiment has progressed.
