ECMELLA 2.0: Single Arterial Access Technique for a Staged Approach in Cardiogenic Shock.

The main drawbacks of venoarterial extracorporeal life support (VA-ECLS) for cardiogenic shock are incomplete left ventricular unloading with concomitant pulmonary edema and vascular access site complications. We describe the staged treatment technique for severe cardiogenic shock with a combination of the Impella 5.0/5.5 (Abiomed Inc, Danvers, MA) and peripheral ECLS (ECMELLA) using a single arterial access in 2 consecutive patients with refinement of the technique in the second case. The arterial cannula was inserted through the same vascular graft in the axillary artery that served as access for the previously implanted microaxial blood pump.
