A Successful Case of Central ECMO with a Transapical Left Ventricular Vent for Fulminant Myocarditis / 日本心臓血管外科学会雑誌

ABSTRACT

We report a successful case of fulminant myocarditis treated with central ECMO with a transapical left ventricular vent (TLVV). A 33-year-old man was diagnosed with fulminant myocarditis with acute biventricular failure. Using a cardio-pulmonary bypass, we introduced central ECMO with ascending aortic perfusion, right atrial venous drainage and TLVV. After ancillary circulation, his cardiac function gradually improved. The endotracheal tube was removed 5 days after the surgery (POD 5), and he was weaned from ECMO on POD 7 and discharged on POD 38. Although there are many cases in which peripheral veno-arterial ECMO (VA-ECMO) is used for fulminant myocarditis, there is a drawback to VA-ECMO left ventricle (LV) unloading may be incomplete. Insufficient LV unloading may cause pulmonary congestion or disadvantage in myocardial recovery. TLVV can be used as a solution to unload the left ventricle. Central ECMO with TLVV should be useful therapy for fulminant myocarditis.
