Extracorporeal membrane oxygenation is rapidly becoming a preferred therapy for short-term hemodynamic support in cardiogenic shock, along with the use of devices such as Impella (Abiomed, Andover, MA). The two together can create unique hemodynamics resulting in altered presentation of common hemodynamic conditions such as tamponade. We present a case of a patient with fulminant myocarditis requiring veno-arterial extracorporeal membrane oxygenation and Impella support. The patient later developed a pericardial effusion with atypical tamponade physiology which masked the left ventricular systolic function recovery. We further highlight the complex hemodynamics of cardiac tamponade in patients with such mechanical circulatory support and its implications on echocardiography.
