Mycobacterium chimaera Isolates from Heater–Cooler Units, United Kingdom [PDF]
Emerging Infectious Diseases, 2017 In their recent article, Svensson et al. provided results of an investigation into contamination of heater–cooler units (HCU) used in open-chest surgery with Mycobacterium chimaera in Denmark (1). We write to provide further information on the UK isolates included in their study.

Identification of Mycobacterium chimaera in heater-cooler units in China. [PDF]
Sci Rep, 2018 AbstractA global outbreak of infections due to Mycobacterium chimaera has been linked to the LivaNova (formerly Sorin) 3 T heater-cooler units (HCUs). We performed a study to investigate M. chimaera from HCUs in China. Water samples were collected from all 3 T HCUs (n = 5) at our hospital in May 2017.

Proof of Concept for Ozone-Based Disinfection of Heater Cooler Units [PDF]
Current Directions in Biomedical Engineering, 2020 Heater Cooler Units (HCUs) are frequently used not only during heart surgery but also in ECMO therapy to regulate the blood temperature of patients. It is known from cardiac surgery that the water circuits of HCUs can be bacterially contaminated and ...
