Blockage of extracorporeal circulation during emergency surgery for fulminant infective endocarditis

A 37-years-old man with a history of alcohol abuse and pancreatitis, presented to the emergency department with a 1-week history of progressively worsening dyspnoea with a fever up to 39°C. Echocardiography revealed bicuspid aortic valve with additional mobile structure and perforation of leaflet with acute aortic regurgitation. Due to rapidly deteriorating condition of the patient, a decision about immediate surgery was made. In the operating room, cardiac arrest in the asystole mechanism occurred. Extracorporeal circulation was turned on during direct heart massage. After opening of the aorta, the circulation was blocked by total clogging of the arterial line filter by fibrine deposits. The oxygenator was replaced which resulted a break in extracorporeal circulation lasting about 10 min. Patients survived surgery and was discharged after 6 week antibiotic therapy.
