Neonatal Gerbode Defect Resulting in Cardiogenic Shock

Congenital Gerbode defects, consisting of a deficiency in the membranous septum causing left ventricle-to-right atrium shunting, are rarely hemodynamically significant. Here, we present the case of a neonate with a large unrestrictive Gerbode defect, patent foramen ovale, patent ductus arteriosus, and pulmonary valve insufficiency resulting in a circular intracardiac shunt and cardiogenic shock. The patient was managed with venoarterial extracorporeal membrane oxygenation followed by neonatal Gerbode defect repair. After repair, the patient had an uncomplicated postoperative course. To our knowledge, a neonatal congenital Gerbode defect resulting in cardiogenic shock is exceedingly rare.
