Case report: Giant coronary aneurysm caused by Kawasaki disease: follow-up with echocardiography and multidetector CT angiography.

Abstract

Giant coronary artery aneurysms caused by Kawasaki disease are not common; however, they are one of the most serious complications and can be fatal. Here, we describe a 5-year-old girl with Kawasaki disease who initially had normal coronary arteries. Despite intravenous immunoglobulin, she developed progressive giant coronary artery aneurysms. Echocardiography is a non-invasive tool for imaging the condition but it does have some limitations, whereas selective coronary angiography is the gold standard. However, multidetector CT may be a better non-invasive tool, alternate to invasive catheterized selective coronary angiography, in the long-term follow-up of patients with a giant coronary aneurysm.
