I was recently diagnosed with mitral valve prolapse. I was admitted to the hospital with shellfish poisoning, and because my ECG showed some abnormality (T-wave inversion), they did an echocardiogram on me, and the cardiologist said that my mitral valve 'looked fleshy' and that there was 'myxomatous degeneration' of the valves. She said I was OK, but on looking it up on the net, I read about complications like mitral regurgitation. What are the chances of this happening? I get attacks of chest pain sometimes, and I had always attributed this to acidity, although not relieved by antacids. I understand that 'atypical chest pain' is one of the features of MVP. Why does that happen? And do I need to take antibiotics before surgical procedures, like a tooth extraction? Is it true that MVP patients have an 'asthenic body habitus'? I am tall and very thin (the doctor said I showed Marfanoid features). I am a 22 year old woman majoring in Biology. Thank you very much.
