(a and b) Phase-contrast images for assessing the flows across the ascending aorta

Time–flow curves obtained using phase-contrast sequences across various vascular structures: (a) aorta; (b) right pulmomonary veins; (c) left pulmonary veins; (d) hepatic veins; (e) right and left superior vena cava, azygous vein

Gadolinium-enhanced 3D MR angiography. (a) Maximum intensity projection showing the bilateral SVC, pulmonary arteries and the bilateral Glenn anastamoses. (b) Maximum intensity projection showing the azygous continuation of IVC, draining into the RSVC. (c and d) 3-D reconstructions: (c) the orientation of the cardiac mass, great artery relationship, pulmonary arteries and Glenn anatomy (coronal plane); (d) is an oblique view from a left-superior perspective, showing the bilateral SVC, the azygous vein, the aorta, and their relationship to each other and other cardiac structures

Line diagram showing the flows (in L/min) obtained across various vascular structures using phase-encoded velocity mapping. The flow values are encircled (RSVC – right superior vena cava AV – azygous vein, LPA – left pulmonary artery, LUPV – left upper pulmonary vein, LLPV – left lower pulmonary vein, MPA – main pulmonary artery, RA – right atrium, RV – right ventricle, RPA – right pulmonary artery, RLPV – right lower pulmonary vein, RUPV – right upper pulmonary vein, RHV – right hepatic vein, LHV – left hepatic veins), LSVC – left superior vena cava

Line diagram representing the basic anatomy and the physiological information obtained on cardiac catheterization. SPO₂ obtained through blood gas analysis at various sites are encircled. Mean pressures recorded are shown in rectangular blocks (AzV – azygous vein, ED – ventricular end-diastolic pressure, LPA – left pulmonary artery, LUPV – left upper pulmonary vein, LLPV – left lower pulmonary vein, MPA – main pulmonary artery, RA – right atrium, RV – right ventricle, RPA – right pulmonary artery, RLPV – right lower pulmonary vein, RUPV – right upper pulmonary vein, RHV – right hepatic vein, LHV – left hepatic veins)
