(A) After initial delineation of the anatomy, a guidewire circuit was established between the right internal jugular vein and the right femoral vein (Online Video 4). (B) The SVC was occluded using a 34-mm Amplatzer sizing balloon (St. Jude Medical, St. Paul, Minnesota). Measurements were taken of the SVC angiogram and of the inflated balloon. (C and D) Patency of the anomalous right upper PV (RUPV) to the LA was confirmed with angiography from the RUPV (white arrows) while the balloon remained inflated in the SVC in anteroposterior and right lateral views. (E and F) In 1 patient, rotational angiography was performed during an injection of contrast in the RUPV (white arrow), showing laminar flow towards the LA (selected frames and Online Video 5). (G,H,I) A simultaneous transesophageal echocardiogram confirmed the anatomical relationships and continuity between the SVASD (G,H,I) (Online Video 6), the anomalous PVs (white arrows) and the atria (G and I) (Online Video 7).
