Veno-arterial extracorporeal membrane oxygenation is used in patients requiring biventricular support; however, its use increases the afterload. In patients with severe aortic insufficiency or severe left ventricular disfunction, it will increase left-side filling pressures, hence the need for left ventricle unloading with an additional mechanical circulatory support device. We present a case of a patient with cardiogenic shock and severe aortic insufficiency who underwent left atrial veno-arterial extracorporeal membrane oxygenation and provide a step-by-step explanation of the technique.
