ABSTRACT
Enlargement of the bulboventricular foramen (BVF) in double-inlet left ventricle or the ventricular septal defect (VSD) in tricuspid atresia with transposition of the great arteries is one approach for prevention or treatment of systemic ventricular outflow obstruction. Most often, BVF/VSD restriction is bypassed preemptively or addressed directly at the time of Glenn/Fontan procedures as part of staged univentricular palliation. We describe a patient who underwent enlargement of a restrictive VSD during Fontan completion and subsequently presented with an asymptomatic pseudoaneurysm of the right ventricle at the ventriculotomy site.

Ultrasound is exquisitely sensitive for the identification of portal vein pneumatosis, which in neonates is commonly caused by necrotizing enterocolitis. We describe the ultrasound finding of systemic arterial pneumatosis in a case of necrotizing enterocolitis associated with congenital heart disease. A combination of a patent ductus venosus and an extracardiac right-to-left shunt via the great vessels through a patent ductus arteriosus provided a pathway for the pneumatosis from the portal vein to the abdominal aorta.
