View larger version (111K): [in a new window]   Figure 1 Magnetic resonance angiography (A) and X-ray coronary angiography (B) image of a left anterior descending coronary artery aneurysm (LAD an) in a patient with Kawasaki disease. LV = left ventricle; R. Atrium = right atrium; RCA = right coronary artery.
