Left coronary artery stenosis with post-stenotic aneurysm after arterial switch operation before and after coronary revascularisation surgery

Abstract

AbstractWe report the case of a child with severe and atypical stenosis of the left main coronary artery, which occurred late after arterial switch operation for transposition of the great arteries. Cardiac computed tomography accurately defined the lesion, showing the presence of post-stenotic dilation, guided the surgical approach and assessed coronary patency after revascularisation surgery.
