Figure 1 : Parasternal long-axis view (1-A) and apical 4-chamber view (1-B) of 2-dimensional transthoracic echocardiography during the first examination. Dilatation of the RA and ventricle and intraventricular septum displaced to the left ventricle, predominantly in diastole.
RA, right atrium; RV, right ventricle; LA, left atrium; LV, left ventricle
Figure 2 : Contrast-enhanced CT scan showing PAPVC and sinus-venosus ASD (white arrow). In axial planes, the right upper pulmonary vein (red arrow) connects the SVC (2-A), and the right lower vein (blue arrow) connects the RA (2-B). Three-dimensional CT scan also clearly identifies PAPVC from the back (2-C) and front view (2-D). The translucent vessel shows pulmonary artery.
CT, computed tomography; PAPVC, partial anomalous pulmonary venous connection, sinus-venosus ASD; sinus-venous atrial septal defect; RA, right atrium; RV, right ventricle; LA, left atrium; PA, pulmonary artery; SVC, superior vena cava
Figure 3 : Modified right ventricular inflow view projected at the apical long-axis view of the second transthoracic echocardiography examination. In simultaneous view with color Doppler, Figure 3-A shows superior sinus-venosus ASD (white arrow) and SVC with increased blood flow. The right lower pulmonary vein (yellow arrow) connects to the RA, parallel to PA (3-B). The right upper pulmonary vein (red arrow) connects to the SVC just proximal to the RA (3-C).
RA, right atrium; LA, left atrium; PA, pulmonary artery; SVC, superior vena cava; ASD, atrial septal defect
