PURPOSE: The left ventricular assist system (LVAS) is often used for end-stage heart failure. However, in severe lung disorder, the patient needs extracorporeal membrane oxygenation (ECMO) because oxygenation using only a ventricular assist system (VAS) is insufficient. We report a successful case of combining the use of LVAS and right VAS (RVAS) with ECMO. METHOD: A 40-year-old female developed cardiogenic shock secondary to end-stage dilated cardiomyopathy, and percutaneous cardiopulmonary support (PCPS) was initiated. An echocardiogram showed a low ejection fraction (11%), and she underwent implantation of an LVAS (Toyobo Ventricular Assist System). She also required a RVAS with ECMO shunting between the right and left atrium because there was insufficient oxygenation resulting from pulmonary dysfunction followed by severe lung edema. RESULT: Pulmonary function recovered successfully, and the RVAS-ECMO was removed after 7 days of support. There were no complications after operation, such as infection, bleeding, or systemic embolization. CONCLUSION: LVAS combined with RVAS-ECMO in right and left atrial cannulation is a useful option for patients with severe pulmonary damage.
