Modifications were made to the adult OCT protocol to adapt this technique for children. Serial cross-sectional area measurements of the lumen, intima, and media were made. Entire imaging data were analyzed for the presence of qualitative changes. Seventeen children were evaluated (5 patients with KD; 12 TX recipients). In patients with KD, angiography was normal. However, OCT imaging revealed that significant vessel wall abnormalities were present in all children including intimal thickening (intima\/lumen cross-sectional area ratio&gt;0.4), loss of the normal layered structure of the vessel wall, white thrombus, calcification, and neovascularization. There was extensive destruction of the internal elastic lamina. In TX recipients, angiography was normal; however, intimal thickening (intima\/media cross-sectional area ratio&gt;1) was seen in 9 of 12 patients. The median intima\/media cross-sectional area ratio was 1.18.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>In this initial experience with OCT in children, we have identified significant coronary abnormalities with OCT that are angiographically silent in children with a history of coronary aneurysms because of KD and in pediatric TX recipients.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circimaging.113.001764","type":"journal-article","created":{"date-parts":[[2014,5,30]],"date-time":"2014-05-30T07:22:21Z","timestamp":1401434541000},"page":"671-678","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":30,"title":["Feasibility of Optical Coherence Tomography in Children With Kawasaki Disease and Pediatric Heart Transplant Recipients"],"prefix":"10.1161","volume":"7","author":[{"given":"Kevin C.","family":"Harris","sequence":"first","affiliation":[{"name":"From the Division of Pediatric Cardiology, Department of Pediatrics (K.C.H., A.M., A.D.S., J.E.P., M.C.K.H.) and Division of Cardiology, Department of Medicine (A.Y.F.), University of British Columbia, Vancouver, Canada;
