Emergency Use of Occlutech® Atrial Flow Regulator Device Facilitates Weaning From Veno-Arterial Extracorporeal Membrane Oxygenation in a Patient With Severe Pulmonary Arterial Hypertension.

Pulmonary arterial hypertension (PAH) is a severe and progressive disease. Treatment options include anti-PAH medications, continuous intravenous therapies, and diuretics. Lung transplant is required in many cases. Atrial septostomy is an under recognized option in symptomatic patients on maximal PAH therapy. However, creating a sustainable and restrictive atrial communication is challenging with existing devices. We describe emergency use of the Occlutech® Atrial Flow Regulator, a novel device, in a 35-year-old female with PAH supported on veno-arterial extracorporeal membrane oxygenation after postpartum decompensation.
