Cardiac Structural Anomalies and Repair

To assess why the results of 2-dimensional echocardiography (2-D echo) for diagnosis of coronary aneurysm in patients with Kawasaki disease differed from those of cineangiography, the macroscopic, postmortem, angiographic and 2-D echocardiographic findings of 8 autopsied hearts of infants and children with Kawasaki disease were compared. Postmortem angiography and 2-D echo yielded similar results in aneurysms in which there was no thrombus, organization or marked thickening of the arterial wall. However, in aneurysms with complete or incomplete occlusion of the dilated cavity due to thrombi, organization or marked thickening of arterial wall, angiographic results reflected only the free cavity of the coronary aneurysm, but could not detect the original aneurysm. Two-dimensional echocardiography disclosed an echo-free space representing the original aneurysm, in which some materials, suggesting thrombi or organization, were found. However, it did not reveal whether the aneurysm was occlusive. This finding indicates that the discrepancies between the results of cineangiography and 2-D echo are attributable to the formation of large thrombi, organization or marked thickening of the arterial wall in the aneurysmal cavity. It is clinically important to know these limitations of angiography and 2-D echo.
