The First Successful Transcatheter Closure of an Inferior Sinus Venosus Defect with Anomalous Drainage of the Right Lower Pulmonary Vein Using Bare and Covered Stents: A Single-Case Report

Figure 17

Postprocedural computed tomography angiogram showing (a) a sagittal image and (b) a rendered image of a patent 3-stent structure in the inferior vena cava. The stent structure covers the sinus venosus defect (SVD) with the upper end almost opposed to the interatrial septum causing a small residual opening (black arrow) and unobstructed blood flow from the right lower pulmonary vein (RLPV) to the left atrium (a). The superior segment of the covered stent should be flared by balloon to prevent residual shunt.
