Mitral Valve Endocarditis: A rare Manifestation of Lyme Disease.
Valvular involvement in Lyme disease is rare. Confirmation of Borrelia species as the causative agent by Polymerase Chain Reaction (PCR) was done in a few cases in Europe and the US. We describe a case of mitral regurgitation with a preoperative diagnosis of myxomatous mitral valve degeneration. During surgery, the surgeon suspected infective rather than degenerative; etiology; tissue cultures were negative. However, universal bacterial PCR on explanted valve tissue detected Borrelia burgdorferiDeoxyribonucleic Acid(DNA). If a surgeon suspects infective endocarditis at the time surgery, appropriate specimens should be sent for histopathology, culture, and PCR.
If I’ve said it once, I’ve said it 1,000 times: researchers need to obstain from using the word “rare” in anything they write about MSIDS. Nobody has a clue about numbers. Testing misses over half of all cases and this study is a perfect example in that it proves tissue cultures can be negative yet a person can still be infected with Lyme. Lyme experts have talked about seronegativity for decades yet mainstream medicine continues to deny it exists. This must change.
Lyme/MSIDS causes all sorts of heart issues:
