Figure 5: Magnetic resonance imaging in a patient with sinus venosus atrial septal defect and partial anomalous pulmonary venous return. (a and b) Images from a steady state free precession cine 4-chambered stack show the superior sinus venosus defect (arrow). There is severe dilation of the right-sided chambers. (c and d) Reconstructed images from magnetic resonance angiography show dilation of the central pulmonary arteries. The patient had a significant left-to-right shunt with Qp/Qs of 3.6. RV = Right ventricle, RA = right atrium, PA = Pulmonary artery
