Repair of Sinus Venosus Defect and Anomalous Pulmonary Veins Associated With Vein of Galen Malformation.

Sinus venosus defect (SVD) is a deficiency in the sinus venosus portion of the atrium, often associated with partial anomalous pulmonary venous connections. In patients with vein of Galen malformation (VGAM), SVD provides a unique challenge with respect to embolization treatment. In our case, the child had percutaneous device closure of the SVD prior to VGAM embolization. Nine years later, he required surgical removal of the SVD device and Warden procedure due to progressive right-sided cardiac enlargement.
