Figure 4. Partial anomalous pulmonary venous connection at ECG-gated CT performed for preoperative evaluation of coronary artery anomalies in a 37-year-old woman. Thin-section axial CT scan shows an anomalous connection of the superior right pulmonary vein (rPV) (arrow) to the right atrium via the superior vena cava (SVC). The origin and course of the coronary arteries (not shown) were normal. lPV = left pulmonary vein, AV = aortic valve.
