I am 46 years old with a history of MVP. I had breast cancer five years ago treated with lumpectomy, chemo--CMF, and radiation. The tumor was in the medial aspect of my chest; 8 'clock
in the left breast. I now have bothersome symptoms that I associated with MVP. An echo saw that there was only trace regurgitation of the mitral valve, but mild to moderate regurgitaion of the tricuspid valve. The symptoms that I'm having include: very strong palpitations with a few seconds pause in the heartbeat, shortness of breath after mild exertion, dizziness, and diminished capacity for excersise. My cardiologist has ordered a Holter monitor, blood work, a repeat echo, and a stress test, although he doesn't seem to think it is anything more than an annoyance. I am worried about the tricuspid regurgitation since I have no history. Could the symptoms be from the tricuspid regurgitaion or just the MVP?
