The Haemopump is an intra‐arterial, axial flow, temporary left ventricular assist device. The intra‐cardiac pump assembly is connected by a flexible drive shaft to a high speed motor and a drive console. The pump is placed in the left ventricle via the femoral artery, iliac artery or abdominal aorta. Blood is withdrawn from the left ventricle and pumped in a continuous, non‐pulsatile fashion into the descending thoracic aorta. We report the use of the Haemopump to provide circulatory assistance in 2 patients with severe graft dysfunction following cardiac transplantation. Both patients were successfully weaned from the Haemopump after 6 and 3 days of support. The first patient subsequently died of overwhelming fungal sepsis and the other remains well 3 months after transplantation with normal left ventricular function. The Haemopump is an effective temporary cardiac assist device for application in severe left ventricular failure.
