I started robotic cardiac surgery programme at Escorts Heart Institute in December 2002 and since then performed 450 robotic cardiac cases with excellent results.
Besides clinical work I am actively involved in research and already published more than 75 scientific papers and chaired scientific sessions in national and international conferences in USA, UK, China, Italy, Japan, France and Far East Countries.
I have already operated more than 1200 cases with port access technology.
Another area of my interest is redo cardiac surgery and I have already performed more than 650 redo cardiac cases.
