Total percutaneous biventricular assist device implantation for fulminant myocarditis.

We report an effective therapeutic approach of mechanical circulatory support for a patient with cardiogenic shock and respiratory insufficiency due to fulminant myocarditis. An Impella® 5.0 was utilized as a left ventricular assist device (VAD) and percutaneous veno-pulmonary extracorporeal membrane oxygenation (ECMO) as a right VAD. These devices were implanted without sternotomy or thoracotomy. Although a combination of Impella and veno-arterial ECMO has been reported as percutaneous biventricular support, there are concerns that this combination is not beneficial for myocardial recovery in patients with respiratory insufficiency, because Impella expels insufficiently oxygenated blood from the left ventricle to the coronary arteries. Our approach took advantage of percutaneous implantation of ECMO and temporary VAD, eliminating the drawbacks of both devices, thus providing a more effective and less invasive form of temporary biventricular support.
