Lateral wall ischemia secondary to funnel-shaped left main coronary artery aneurysm with stenotic osteoproximal left circumflex coronary artery in a child with recent recovery from kawasaki disease: A case report and review of literature

Abstract

We present a case of funnel-shaped aneurysmal dilatation of left main coronary artery (LMCA) with aggressive stenosis of osteoproximal left circumflex coronary artery presenting with lateral wall coronary ischemia in a 6-year-old school-going child who recovered from Kawasaki disease (KD) 1 month back. Although aneurysmal dilatation of LMCA during first 2 months of recovery from KD is well known, with median duration for the development of stenotic lesion in coronaries after KD is approximately 6 months and all the cases of coronary stenosis described so far have been described in the presence of large coronary artery aneurysm, our case is rare to illustrate aggressive stenosis of osteoproximal left circumflex coronary artery just after 1 month of recovery in spite of the presence of small coronary artery aneurysm.
