    AbstractSevere pulmonary edema, secondary to left ventricular afterload increment, is a common problem occurring in patients receiving venoarterial extracorporeal membrane oxygenation. No consensus is currently available for its management, but several devices/procedures have been described, including an Impella device (Abiomed), balloon atrial septostomy, intraaortic balloon counterpulsation, or an additional venous cannula, as possible adjuncts. We report the feasibility and efficacy of the atrial flow regulator device (Occlutech) for left ventricular unloading in a 58-year-old patient receiving extracorporeal membrane oxygenation. However, the benefits of this device relative to simple balloon atrial septostomy need to be further investigated.Copyright © 2021 American College of Chest Physicians. Published by Elsevier Inc.
