Successful treatment of near-fatal fulminant myocarditis using bi-ventricular assist device support.

Fulminant myocarditis is a rare but fatal serious disease that may cause prolonged native cardiac dysfunction with multiorgan failure despite temporary mechanical circulatory support with percutaneous venoatrial extracorporeal membrane oxygenation (VA-ECMO) or intraaortic balloon pumping (IABP). A 26-year-old man with fulminant myocarditis developed life-threatening multiorgan failure after 8 days support by VA-ECMO and IABP. He was transferred to our institution with prolonged cardiac dysfunction on hospital day 8; massive pulmonary edema developed into severe pulmonary dysfunction. Immediately after admission, VA-ECMO and IABP were switched to a paracorporeal pneumatic left ventricular assist device (LVAD) and right centrifugal ventricular assist device with an ECMO circuit shunting from the right ventricle to the pulmonary artery (RVAD-ECMO). After intensive care focusing on respiratory dysfunction, ECMO was successfully weaned, and the right ventricular assist device was switched to a durable paracorporeal pneumatic right ventricular assist device. The paracorporeal bi-ventricular assist devices were finally replaced with an implantable non-pulsatile LVAD on hospital day 181. Currently, 1 year after discharge, the patient is at home awaiting heart transplantation. Combined LVAD and RVAD-ECMO appear to be useful for resolving severe pulmonary edema due to unnecessarily long VA-ECMO support as well as kidney or liver dysfunction caused by circulatory collapse.
