In this short report, we present a rare scenario involving a 60-year-old male patient, in whom higher pump speed and suction mimicked external compression of the left ventricle. Surgical revision revealed excessive suctioning of the left ventricle and left atrium by the left ventricular assist device, leading to atrioventricular groove distortion that mimicked external compression of the left ventricle. After adjustment of the pump speed, obstruction of the inflow cannula and collapse of the left ventricle were resolved.
