The Stockert 3T heater-cooler system used to regulate body temperature during cardiopulmonary surgeries has been linked to nontuberculous mycobacteria (NTM) infections and other serious side effects.

Patients who undergo open-heart surgery and other cardiopulmonary operations where the Stockert 3T heater-cooler system is used, may be at risk for contamination by Mycobacterium chimaera, a bacteria that research shows may grow in the device’s water tanks and be released into the operating room through the heater-cooler’s exhaust vent. If you have been diagnosed with a nontuberculous mycobacteria (NTM) infection, and you believe the Stockert 3T system to be at fault, consult an experience product liability lawyer today to discuss your legal options. You may have grounds to file a product liability lawsuit against Stockert 3T maker LivaNova, in order to pursue the financial compensation you deserve for your injuries, medical expenses, pain and suffering, and other damages.

What is the Stockert 3T Heater-Cooler System?

A medical device used to cool and re-warm a patient’s blood during surgery that may contaminate sterile operating rooms with Mycobacterium chimaera bacteria.

The Stockert 3T heater-cooler system is a medical device used to regulate the patient’s body temperature during cardioplegic surgeries that stop the heart and blood flow, such as transplant surgeries or cardiac bypass surgeries. The Stockert 3T system uses a closed-water circuit with three separate water tanks to regulate the temperature of oxygenators, bypass machines, heating or cooling blankets, and other equipment designed to keep blood at the optimal temperature for patients undergoing such operations. Approved by the FDA in 2006, the Stockert 3T was originally developed by the Sorin Group, which merged with another European medical device maker in 2015, to become what is now LivaNova.

Possible Side Effects Leading to a Stockert 3T Heater-Cooler Systems Lawsuit

The side effect most often associated with the Stockert 3T heater-cooler system is a nontuberculous mycobacteria (NTM) infection, which can cause serious illness or possibly even death. The most common symptom of this type of infection, possibly caused by exposure to invasive Mycobacterium chimaera, is unexplained fever, which can take several months or even years to develop, depending on how slowly the bacteria grows. Other possible symptoms of a nontuberculous mycobacteria infection include the following:

  • Night sweats
  • Loss of energy
  • Joint or muscle pain
  • Difficulty breathing
  • Redness, heat or pus around the surgical incision
  • Nausea
  • Vomiting
  • Persistent cough or cough with blood
  • In infants, a failure to grow or gain weight

Diagnosing a nontuberculous mycobacteria infection can be challenging, because the infection has a long incubation period before symptoms begin to arise, and the infection is also difficult to successfully treat, the mortality rate being nearly 50%. In many cases, an infected patient requires a second surgery to remove an implant that may have become contaminated with M. chimaera during the original operation.

Link Between Stockert 3T and NTM Infections

Nontuberculous mycobacterium are organisms that exist in the environment in water and soil and don’t normally pose a risk to human health. However, research has shown that the Stockert 3T heater-cooler system may put patients at risk for infections caused by NTM, due to the use of water tanks, which provide the unit with temperature-controlled water. Although the water in the tanks never actually comes in contact with patients, the water can turn into a gas and pass through the device’s exhaust vent, thereby entering the otherwise-sterile operating room. If the water contains the M. chimaera bacteria, it can spread through the air and contaminate sterile equipment, the patient’s chest cavity, and any implants, such as new valves or vascular grafts, possibly causing an NTM infection. This type of infection poses a serious risk for people who are ill, have compromised immune systems or chronic diseases, and may therefore be more susceptible to infection, and of the 32 cases of M. chimaera reported to the FDA between 2010 and 2015, all involving patients who underwent surgeries using the Stockert 3T system, nearly half of the patients died.
