MRI of supracristal ventricular septal defects.
The MR features of two cases of supracristal ventricular septal defect are described. In both patients, axial SE T1-weighted images demonstrated a defect between the base of the aorta and the upper posterior aspect of the right ventricular infundibulum. Cine MRI in the two cases showed left-to-right shunting with a flow jet in the distal right ventricular outflow tract that propagated into the main pulmonary artery. Both patients had prolapse of the right sinus of Valsalva, and one had aortic insufficiency.
