Mycobacterium chimaera infection - Heater-cooler units

You may have seen reports related to the potential risk for Mycobacterium chimaera infection associated with certain heater-cooler units, which are used to warm and cool blood during adult and pediatric open heart surgery. AHS has used and does use these heater cooler units at the Foothills Medical Centre in Calgary and at the Mazankowski Alberta Heart Institute and the Stollery Children’s Hospital in Edmonton.

AHS is notifying discharged open-heart surgery patients who may have been exposed to M. chimaera during their procedure. The public notification will include adults and parents or guardians of pediatric patients.

We are monitoring the situation very closely and will continue follow all Health Canada guidance and direction related to the use of heater cooler machines.
