FIGURE 6. Superimposed displays of a coronary angiogram and an exercise 3D surface map obtained from an 11-y-old girl with Kawasaki disease. (A) The unified image depicts apical and inferior hypoperfusion and a coronary aneurysm (arrow) with distal stenosis in the left anterior descending artery. The right coronary artery (arrowheads) was filled by collateral vessels through the septal branch because the proximal portion of the right coronary artery was occluded. (B) After bypass surgery, the nongated unified image shows homogeneous left ventricular perfusion with patency of the left internal mammary artery bypass graft at exercise. (C and D) ECG-gated unified images at end-diastole (C) and end-systole (D) show normal regional wall motion and count increase in the left ventricular wall.
