Heater-cooler devices used in cardiac surgery – risk of infection with Mycobacterium species update

Updated advice from manufacturers on device management for systems known or suspected to be contaminated with Mycobacterium chimaera.

Action

Notify the manufacturer and MHRA:

  • of any heater-coolers known or suspected to be contaminated with Mycobacterium chimaera. The devices should be removed from service
  • if you observe specific risks associated with the use of the heater-coolers

Notify Public Health England and MHRA of any cases where patients have been infected with Mycobacterium chimaera

Ensure that the people responsible for operating and maintaining heater coolers are aware that specific advice has been issued by LivaNova (Sorin) and Maquet – details below.

LivaNova has issued an updated field safety notice (FSN) for 3T systems. Users must now follow additional guidance on:

  • positioning of heater-coolers within the operating theatre
  • when to use new or disinfected accessories

Maquet has also issued an FSN. Users must now follow guidance on:

revised instructions for use – cleaning, descaling and disinfecting heater unit HU 35 when to use new or disinfected accessories *a new weekly routine disinfection as well as a high level disinfection and biofilm reduction.

Deadlines for actions

Actions underway: 4 weeks

Actions complete: 5 weeks

Device details

LivaNova (Sorin) has issued operational advice for the 3T heater cooler unit. Maquet has updated the HU35 cleaning and disinfecting instructions and will issue updated instructions for the HCU20, HCU30 and HCU40 soon.

Problem / background

MHRA issued a Medical Device Alert (MDA) on 11 June 2015 concerning all manufacturers of heater-coolers and the risk of patient infection with Mycobacterium species; this advice remains current.

This information has highlighted an infection risk to open-heart surgery patients called non-tuberculous Mycobacterium (NTM).

If the disinfection and maintenance procedures are not strictly followed, organisms can multiply in heater-cooler devices and a biofilm can be formed. The biofilm provides an opportunity for bacteria, including Mycobacteria, to colonise the device. Once colonised, there is a possibility that bacteria can become a source of patient contamination due to aerosolisation when the heater-cooler device is used, or contamination can spread during operational management of the device.
