Regressed Coronary Aneurysm After Kawasaki Disease: An Optical Coherence Tomography (OCT) Study From A Single Institution
Coronary artery aneurysms (CAA) are a serious complication of Kawasaki disease (KD). CAA size regresses in nearly 50% of the cases on follow up. Nevertheless, patients with regressed CAA have an increased risk of ischemic heart disease, myocardial infarction and sudden cardiac death on long-term follow-up. Actual imaging techniques often describe these segments as normal, whereas studies have shown significant endothelial and smooth muscle dysfunction. Optical Coherence Tomography (OCT) is a high-resolution intracoronary imaging modality that characterizes coronary artery wall structure. n.
