Figure 4: Final inferior vena cava angiogram (top) and echocardiogram (bottom) after fenestrated covered stent placement. Top: Contrast now flows through the inferior vena cava stent and into the branch pulmonary arteries. The fenestration is patent with filling of the hepatic vein, but only the inferior vena cava-connecting hepatic vein has opacified. The interlobar connections and anomalous atrial-draining hepatic vein have not filled secondary to flow restriction through the controlled fenestration. Bottom: The inferior vena cava and stent (*) are widely patent with red fenestration flow visible into the hepatic vein (†)
