What Causes Mitral Regurgitation Without Distolic Dysfunction?

I have a diagnosis of trace mitral regurgitation without distolic dysfunction. The ejection fraction is estimated at 52% (>50%NL). My doctor prescribed Propranolol HCL 10MG orally twice a day prn palpitations. My doctor told me I have to take antibiotic before visiting my dentist. I knew I had a murmur since childhood but I am surprised I still have it. Please help me understand my diagnosis.

Cardiologist,  's  Response
Hello,I have gone through your question.Trace Mitral valve regurgitation is not at all serious condition.This is secondary to mitral vale prolapse present since birth.This condition may be totally silent or you may have mild chest pain ,palpitation or giddiness.Propranolol will control these symptoms.Absence of diastolic function is good sign.LVEF 52% is satisfactory function.
whenever anyone undergoes dental extraction the bactaria from tooth may enter blood stream and in setting or Mitral valve prolapse (or any structurally abnormal heart)can initiate serious infectionwithin the heart called endocarditis.so before such procedure antibiotic prophylaxis is recommended.You should have yearly follow up with your cardiologist.
My best wishes
