Figure 2: Postnatal imaging (echocardiography and high resolution 256 slice CT with 3D reconstruction) confirming the diagnosis. This sequence depicts the postnatal echocardiography and high resolution 256 slice CT reconstruction of the anatomy of the lesion. (a) Neonatal echocardiography showing dilated RA and SVC with increased flow in SVC as shown by flow aliasing. (b) Depicts the drainage site of the vertical vein (arrow) into the SVC; the vertical vein is very narrow with turbulent flow. (c) Depicts a coronal view in 256 slice CT showing the confluence of the 4 pulmonary veins forming a CC. (d) A sagittal view in 256 slice CT showing the individual pulmonary veins forming the confluence and ascending up as VV into the SVC. (e and f) Depict the 3D reconstruction of the anatomy of the TAPVC. The individual pulmonary veins are clearly seen joining together forming a very short CC which ascends posterior to the RPA as the obstructed VV into the SVC. RA: Right atrium, LA: Left atrium, SVC: Superior vena cava, LUPV: Left upper pulmonary vein, LLPV: Left lower pulmonary vein, RUPV: Right upper pulmonary vein, RLPV: Right lower pulmonary vein, CC: Common chamber, VV: Vertical vein, DA: Descending aorta, TAPVC: Total anomalous pulmonary venous connection, CT: Computed tomography, 3D: Three dimensional
