So I did some googling n research-
In India-
How many years does it take to become a heart surgeon in India after 12th?
The entire journey of becoming a Cardiologist after 12th requires 11 ½ years, including 5 ½ years of MBBS + 3 years MD + 3 years of DM in cardiology. Various entrance exams are compulsory to be passed before beginning with the study for becoming a Cardiologist.
In US-
How long does it take to become a heart surgeon?
The educational process to become a cardiac surgeon is one of the longest in the medical field. Cardiac surgeons must complete four years of medical school, a 5-year general surgery residency and a 2-3 year specialized cardio or cardiothoracic fellowship.
And Abhimanyu has been practicing Surgeon for a few years because he is counted as one of the best and not a new surgeon. My guess is atleast 3 yrs of practice as a heart surgeon.
Now do the calculations.
