A 62-year-old patient developed cardiogenic shock after acute myocardial infarction and was given venoarterial ECMO support with the extraction cannula placed in the left atrium (LAVA-ECMO). During ECMO he lost pulsatility. A transoesophageal echocardiogram was performed, showing no contractility, closure of the aortic valve, and spontaneous contrast in the left ventricle and aortic root (Fig. 1A and B, Video 1). Valve opening was achieved with chest compressions (Fig. 1C, Video 2). A left intraventricular catheter was connected to the extraction cannula for definitive management (Fig. 1D, Video 3). Chest compressions can be a rescue measure to prevent left chamber thrombosis during left ventricular distension syndrome in which an active left ventricular drainage mechanism is established.
