Hello, Iam post mitral valve replacment and have increaced fatigueand shortnes of breath even when speaking. I am not over weight and I exercise 3 days a week.(but this is becoming difficult) My echo this week showed mitral stenosis, with abnormal motion of the septum/ a ejection fraction of 55%and mild regurgitation of the aortic tricuspid and pulmonic. pulmonary atery pressure is 13-16 mmHg and a mean gradient across the mitral valve prosthesi of 3 mmHg. My blood work came back total chllt. as 320/ HDL-72/TRIG-248 AND LDL198. My diet is very good almost a vegitarian, but my Dr. is not worried about this. Should I be.
