title: Subcostal 2-dimensional echocardiographic imaging of peripheral left coronary artery aneurysms in Kawasaki disease.
abstract: Our previous study provided a new 2-dimensional echocardiographic technique to detect peripheral right coronary artery aneurysms in Kawasaki disease, with use of the subcostal approach. An additional study was performed to detect peripheral left coronary artery aneurysms. Because the left anterior descending artery runs along the anterior interventricular sulcus and the left circumflex artery along the mitral valve ring, these regions were searched for coronary aneurysms by use of the subcostal imaging approach. Among 143 patients with Kawasaki disease, 44 left coronary aneurysms were visualized in 22 patients. Three aneurysms at the origin of the obtuse marginal artery and 1 in the further peripheral site of the left circumflex artery were observed in 3 patients. Two aneurysms at the origin of the second diagonal branch of the peripheral left anterior descending artery were detected. These echocardiographic studies were done prospectively, and their features coincided well in size, shape, and anatomic location with confirmatory angiographic appearances.
