Video 11.10: Cine loop of right atrial-type sinus venosus defect imaged from the subxiphoid long-axis view. Note large defect between the posterior wall of the right atrium and the anterior wall of the right lower pulmonary vein. The interatrial communication is via the left atrial orifice of the right lower pulmonary vein. This illustrates anomalous drainage of the RLPV to the RA but with normal connection. Note the flow from the right lower pulmonary vein and from the left atrium to the right atrium.
