Nontuberculous Mycobacterium Infections Associated With Heater-Cooler Devices [PDF]
Annals of Thoracic Surgery, 2017 Disseminated nontuberculous mycobacterium infections have occurred following surgical procedures involving extracorporeal circulation; contaminated water from heater-cooler devices (HCDs) has been implicated as the source. The purpose of this review was to evaluate the public health concern and to educate physicians who care for this patient population.

Notes from the Field:Mycobacterium chimaeraContamination of Heater-Cooler Devices Used in Cardiac Surgery—United States [PDF]
Morbidity and Mortality Weekly Report, 2016 In the spring of 2015, investigators in Switzerland reported a cluster of six patients with invasive infection with Mycobacterium chimaera, a species of nontuberculous mycobacterium ubiquitous in soil and water. The infected patients had undergone open-heart surgery that used contaminated heater-cooler devices during extracorporeal circulation (1).
