Good Night. I Am A Runner And During This Week,

Good night. I am a runner and during this week, I was diagnosed with severe mitral insufficiency, with rupture of the posterior leaflet. I'm 50 years old, I don't smoke, I don't drink alcohol and I have an excellent diet and physical condition. The doctor told me I'd have to operate, and I'm a little scared, I'd like to know more about the best approach to my condition, types of surgeries and actual success rates and complications. Thank you.
