Mitral Valve Endocarditis: A rare Manifestation of Lyme Disease.

Haddad O, et al. Ann Thorac Surg. 2019.

Abstract

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.

**Comment**

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:

Does this look rare to you?
