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 5

A 3-dimensional model was created to simulate balloon sizing in the inferior vena cava (IVC) (a). The critical point at the IVC-right atrium junction was 20.3 mm. A decision was made to position a 24 mm anchored bare stent (black outlined stent) at this location (b). A long wire was placed in the superior vena cava (SVC), and a short wire was placed in both the left hepatic vein (LHV) and the IVC. The aim of the placement of the bare stent (black outlined stent) and the subsequently positioned covered stent (white outlined stent) was to cover the sinus venosus defect and to ensure no obstruction of blood flow in the LHV and the right hepatic vein (RHV).
