Hi aspirant,

No, you cannot become a Cardiovascular Surgeon after completion of M.Sc Cardiology.

The process goes like this, you need to appear NEET UG entrance exam and study  MBBS course from a recognised College or University.

Then next through NEET PG you need to pursue MD/ MS or DNB in Cardiology specialization.

If you want then you can go for Super Speciality specialization DM in Cardiology by appearing NEET SS entrance for admission into this course.
