Hybrid peratrial double device closure of a patent foramen ovale and sinus venosus defect in an infant with vein of Galen malformation

Abstract

Vein of Galen aneurysmal malformation is the most common cerebral arteriovenous malformation in children. Neurointerventional embolization has improved outcomes with this lesion. An association with cardiac defects has been recognized and can increase the risk of systemic embolic events during treatment. Cardiopulmonary bypass (CPB) to correct the cardiac defect before repair of the malformation may be associated with compromised cerebral perfusion and possible neurologic injury. We describe a successful hybrid peratrial closure of two intracardiac shunts (a patent foramen ovale and a sinus venosus ASD) before neurointervention, avoiding CPB, and eliminating the intracardiac embolic risk during treatment of the vein of Galen malformation.
