So about ten months ago, I saw a new GP, and he said that I have a heart murmur, which is the first time anyone told me that. I am 33 years old and countless doctors over the years have listened to my heart and said nothing. My endocrinologist, who I see every few months, never hears anything.
Anyway, the new GP ordered an echo to be done ten months ago and the radiologist wrote that I have "moderate" mitral regurgitation and a dilated left atrium, though the left atrium dimension was within the normal range. The GP referred me to a cardiologist who quickly looked at the echo report I handed him, listened to my heart, and said that he heard the murmur, but that it didn't sound too bad, and that he thought the radiologist was being "generous" when he said that the regurgitation was moderate. He never did another echo or further tests to evaluate it for himself, which concerned me at the time, but I took his word for it.
My question is, does the "loudness" of the murmur always directly correlate with the severity of regurgitation? The cardiologist suggested that I come back in a year for another "listen", but I am thinking maybe I should get a second opinion? I'm just a little worried because I do a lot of strenuous activity and may have to go with lesser health coverage for a while in the near future. Doctors have misdiagnosed me before, so I tend to be a little suspicious of their conclusions sometimes. Just thought I would see if anyone had any thoughts. Thanks.
