Temporary left ventricular assist devices such as the ImpellaTM are increasingly used in patients with cardiogenic shock. The right ventricle remains the Achilles heel of left ventricular assist device-supported circulation. However, right ventricular failure after implantation of a left ventricular assist device remains incompletely defined and understood. We describe the first case of pulsus paradoxus emerging after the initiation of circulatory support using a left ventricular ImpellaTM device, which is an early sign of right ventricular failure, that was completely abolished after the addition of a temporary right ventricular assist device.
Keywords: Heart failure; cardiopulmonary resuscitation and emergency critical care; mechanical circulatory support; right ventricular failure.
