youll need to excel in college and complete a bachelors degree (typically around 4years) then enroll in and excel in medical school (4 years). After that you need to either match into and complete either (1) a categorical cardiothoracic surgery residency (6 years) or (2) a general surgery residency (5-7 years) followed by a cardiothoracic fellowship (3 years I think). It’s a long road but well worth it if that’s your passion. Hope that helps.
