<unk>  is an abnormal dilatation of a coronary artery segment over 1.5 times the diameter of normal adjacent segment.  An<unk>  can be classified as either saccular (wider than it is long) or fusiform (elongated).<unk>  must be differentiated from coronary artery ectasia; in fact, coronary artery ectasia is a localized arterial dilatation that is graded according to the size of the dilatation in comparison to the normal artery diameter located anywhere in the culprit artery.  A coronary artery ectasia is considered as an<unk>  when the coronary artery dilatation is 1.5 times the normal artery diameter located anywhere in the culprit artery.
