Figure 8b. Supracristal ventricular septal defect in an asymptomatic 42-year-old man with a systolic murmur. (a) Axial ECG-gated spin-echo image shows a defect (arrow) between the base of the aorta and the right ventricular (RV) infundibulum. (b) Axial gradient-echo systolic cine image shows a flow jet (*) from the left ventricle into the right ventricular outflow tract, indicating a left-to-right shunt. (c) Sagittal spin-echo image shows a prolapse (arrow) of the posterior aortic sinus of Valsalva.
