Monitored Anesthesia Care for Axillary Impella 5.5 Placement: A Feasible Option for Patients with Severe Cardiogenic Shock with Relative Contraindication to Intubation.

The Impella 5.5 left ventricular assist device (LVAD) is typically placed in a hybrid operating room with fluoroscopic and echocardiographic guidance under general anesthesia. In this case report, we describe a patient with severe cardiopulmonary failure necessitating an Impella 5.5 as a bridge to heart/lung transplant. Here, we describe the successful placement of the Impella 5.5 with sedation and local anesthesia in order to avoid general anesthesia and the sequelae of positive pressure ventilation in a fragile patient. Impella placement was confirmed with transesophageal echocardiography. This case report demonstrates a novel strategy for placing the Impella 5.5 and, more importantly, opens the possibility to future prospective studies of this technique.
