Simple method of left ventricular assist system exchange from a BVS-5000 to a Toyobo: case report of a patient with fulminant myocarditis.

We implanted a BVS-5000 biventricular assist system in a 29-year-old woman in cardiogenic shock due to fulminant myocarditis. Exchange of the left ventricular assist system (LVAS) from the BVS-5000 to a Toyobo LVAS and weaning from the right ventricular assist system were performed successfully without cardiopulmonary bypass. This simple, less invasive method may be useful for patients requiring LVAS exchange for long-term ventricular support.
