- OBJECTIVES:: To report the late coronary complications and their treatment after ASO. BACKGROUND:: Asymptomatic patients after arterial switch operation (ASO) may have coronary ostial stenosis or obstruction. METHODS:: Since 1980, 279 patients were operated with ASO. At the time of preparing this article, selective follow-up coronary angiograms were done on 81 patients. RESULTS:: Coronary stenosis was found in six patients. A six year-old patient with left coronary artery (LCA) ostial stenosis and a nine year-old patient with conus branch occlusion had good collaterals without a need for further treatment. One patient with LCA obstruction, myocardial infarction, and left ventricular failure was operated with osteoplasty at age of 16 years. In three essentially asymptomatic patients stenting of LCA ostium stenosis was done: in two of them with drug-eluting stents at nine and ten years of age and in one with bare-metal stent at 18 years of age. One of these patients was earlier treated with balloon dilatation at five years of age which caused intimal dissection. CONCLUSIONS:: Asymptomatic patients with an uneventful course after ASO may have coronary obstruction. This necessitates follow-up coronary evaluation in all patients. Stenting of the coronary arteries is an option for treatment. (c) 2010 Wiley-Liss, Inc.
