Pulsus Alternans as a Sign of Right Ventricular Failure After Left Ventricular Assist Device Implantation

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.
