SickKids notifies heart surgery patients of potential infection risk associated with heater-cooler devices
SickKids is contacting patients who have had heart surgery since December 2013 (when the devices first came into use at SickKids) about a potential risk related to their surgery.
TORONTO - The Hospital for Sick Children (SickKids) is contacting patients who have had heart surgery since December 2013 (when the devices first came into use at SickKids) about a potential risk related to their surgery. In addition, a small number of patients who underwent other specific surgeries have been contacted.
A device used to heat and cool the blood during heart surgery has been linked to a rare bacterial infection caused by Mycobacterium chimaera, a type of bacteria known as nontuberculous mycobacteria (NTM). The bacteria may have been present in the machines during manufacturing and there is potential for bacteria-contaminated water contained in the device to be transferred via aerosolization (through the air) in the operating room environment. The chances of getting this infection are very low. The American Centers for Disease Control and Prevention estimates the risk to be less than one per cent.
Many hospitals across the country, as well as in the United States and Europe, use this equipment during heart surgeries and are experiencing the same concerns. We are not aware of any patients who have developed this infection following heart surgery at SickKids.
NTM organisms are commonly found in the environment, from sources such as water and soil. They are typically not harmful to persons exposed to them and rarely cause complications. Most types of NTM that are associated with heater-cooler infections are slow-growing and it can take several months or even years for evidence of an infection to develop.
Features of this infection may include the following: unexplained fever; pain, redness, warmth or pus around a surgical incision; night sweats; joint pain; muscle pain; weight loss; and fatigue; as well as failure to thrive in infants.
If you are a parent of a child who has heart surgery at SickKids from December 2013 to October 2016, we suggest the following actions on your part:
- If your child is experiencing these symptoms, contact your health-care provider. Your health-care provider can contact Cardiology at SickKids as needed. Please bring this letter with you to your health-care provider.

You will be asked to leave your name and phone number and someone will return your call within five business days.
