Mycobacterium chimaera from open heart surgery

“I have a 70-year-old woman with severe multi-vessel coronary artery disease,” the intern told the cardiology fellow. “Do you think she needs a CABG [coronary artery bypass grafting surgery]?”

Open heart surgery is a big deal. Patients can do very well, or they can end up dying from infection, stroke, etc. Recently, an additional risk factor has been identified, that being invasive Mycobacterium chimaera infections. Take a glance at this EID article and analysis by Dan Diekema.  I suspect we’ll be hearing more about M. chimaera infections in the near future. M. chimaera might be a reason for people to think twice before getting their open heart surgery.


Thanks so much for visiting my website! Writing and reading blog posts does take time and we all know that time is in short supply. You and I will both get much more out of this blog if it leads to dialogue. If you found my post useful and wouldn’t mind leaving a brief comment or sharing on social media, I would be grateful. Or if you’re shy about Tweeting but are willing to email me a comment that I can post anonymously or send an anonymous Surveymonkey, that would be great. My posts are generally written quickly, so if you find any factual or grammatical errors, please do let me know. Best regards, Philip Lederer
