Fulminant myocarditis is known as a disastrous disease that requires intensive care with mechanical cardiopulmonary support. Percutaneous cardiopulmonary bypass（PCPS), which is referred to as extracorporeal membrane oxygenation, is usually used for fulminant myocarditis. However, in some cases, PCPS may be ineffective because of circulatory insufficiency and could be associated with various severe complications such as multiple organ failure or leg ischemia. In such cases, placement of a ventricular assist device（VAD）is required. A 46-year-old man with fever and severe fatigue was admitted to a local hospital and diagnosed as having fulminant myocarditis. Although an intra-aortic balloon pump and PCPS were introduced, cardiac function was not recovered, causing multiple organ failure and leg ischemia. Hence, he was transferred to our hospital for further mechanical support. Transesophageal echocardiography（TEE）revealed severe biventricular cardiac dysfunction, and radiography showed pulmonary edema. His total bilirubin level was 6.9mg/dl and platelet level was 3,300/μl. Thus, we implanted a biventricular assist device（BiVAD). At 12 days after the implantation, TEE revealed improvement of cardiac function, and blood biochemical examination revealed recovery of multiple organ function. Thereafter, the patient was weaned from the BiVAD successfully. After the operation, the patient underwent a long rehabilitation. He was discharged 51 days after the operation, without any neurological or cardiac complication.
