What’s the problem?

March 9, 2017 – One of the patients, 60-year-old Robert Gerngross, developed a serious infection about a year after undergoing heart valve replacement surgery at Penn Presbyterian Medical Center two years ago, according to As a result of the infection, Gerngross claims he lost 40 pounds and was forced to undergo a second heart valve replacement.

The other patient, 39-year-old Marisa Karamanoogian, had open heart surgery with a heater-cooler unit at the Hospital of the University of Pennsylvania about a year ago. About a month after the procedure, Karamanoogian began experiencing pectoral pain and other symptoms, and was later diagnosed with an infection, according to the lawsuit.

Heater-cooler machines are used to warm or cool a patient’s blood during cardiothoracic surgery and other medical procedures. The devices consist of tanks that provide temperature-controlled water to external heat exchangers or warming/cooling blankets through closed circuits.

Although the water in the circuits does not come into direct contact with the patient, the U.S. Centers for Disease Control and Prevention (CDC) reports that contaminated water can enter other parts of the heater-cooler or transmit non-tuberculosis mycobacteria (NTM) through the air via the system’s exhaust vent and onto the patient.

Both Gerngross and Karamanoogian filed their lawsuits in the Philadelphia Court of Common Pleas in January 2017.
