I had heart surgery to repair my mitral valve
in November 2007. I was prescribed antibiotic by my cardiologist when I went
in to the dentist even for just a routine cleaning and check-up. That was stopped after about two years. I have not had any antibiotic since then, I'd guess that was 2009.
I now suffer from permanent atrial fibrillation, and take warfarin, an anticoagulant.
