The catheter course was via the right femoral vein, azygos vein, SVC, right atrium (RA), right ventricle, pulmonary artery, PDA to the descending aorta [Figure 1]. A right femoral venous angiogram showed filling of the iliac veins and azygos system, in addition to normal drainage into the IVC [Figures 2 and 3, Video 1].

A right femoral venous angiogram showed filling of the iliac veins and azygos system, in addition to normal drainage into the IVC [Figures 2 and 3, Video 1]. Similarly, the left femoral venous angiogram showed filling of both the IVC and the hemi azygos system [Figure 4, Video 2].
