This article was very informative. I suffer from mitral valve prolapse, with regurgitation, along with other heart disorders. I did not develop the condition until after I had strep so frequently and severely in my 20's that my tonsils were removed at 22. I used to get strep every other month, and was resistant to antibiotics due to the frequency of the infection. Being poor back then, I was never informed of the heart risk, and didn't find relief until a surgeon offered to remove the tonsils pro bono. Thanks for this article! Knowledge is power, and I'm glad to know where the ailment most likely came from.
