Stockert Heater-Cooler System 3T is manufactured by LivaNova PLC (formerly Sorin Group Deutschland GmbH) to provide temperature controlled water to heat exchanger devices, which help regulate patient's body temperature during cardiothoracic, cardioplegia procedures for six or fewer hours. It was approved by the U.S. Food and Drug Administration (FDA) via a 510K process in 2006. It is also called Sorin 3T.
Stockert Heater-Cooler System 3T has got linked to the possibility of causing nontuberculous mycobacteria (NTM) infections, which is specifically Mycobacterium chimera. This bacteria is believed to be emitted through vapors which come from the heater-cooler system and cause deadly infections in vulnerable patients.
As per CDC, above 250,000 heart bypass procedures are performed in the United States every year and heater-cooler devices are used routinely. Also, the risk seems very high with patients who have had valves or prosthetic products. Research says infections caused by this bacteria are severe and can also cause a fatality.
