Acutely severe myocarditis successfully treated by percutaneous cardiopulmonary support applied by a newly developed...

The feasibility of using the heparin-bound percutaneous cardiopulmonary support system (PCPS) for prolonged extracorporeal circulation in patients with acute severe myocarditis is demonstrated. The case histories of 2 patients with cardiogenic shock caused by acute myocarditis are presented; both were successfully treated with long-term PCPS using a newly developed heparin-binding oxygenator and circuits without changing the oxygenator. The courses of both patients remain uneventful more than 12 months after discharge. We also discuss the clinical aspects of using heparin-bound PCPS in patients with acute severe myocarditis.
