Overview
Coronary artery aneurysm is an abnormal dilatation of a coronary artery segment over 1.5 times the diameter.[1] Ectasia is a localized arterial widening (dilatation) that usually manifests itself as a bulge, its presence may lead to weakening of the wall and eventual rupture. A coronary artery ectasia can be classified as follows: grade 0 corresponds to absence of any ectasia, grade 1 is present when there is visual assessment of ectasia >1 & < 1.5 times the normal artery diameter located anywhere in the culprit artery and grade 3 is present when there is visual assessment of an aneurysm > 1.5 times the normal artery diameter located anywhere in the culprit artery. An aneurysm can be further classified as either saccular (wider than it is long) or fusiform (elongated).
Example
Grade 0
None – no ectasia present.
Grade 1
Ectasia – visual assessment of ectasia >1 & < 1.5 times the normal artery diameter located anywhere in the culprit artery.
Grade 2
Aneurysm – visual assessment of an aneurysm > 1.5 times the normal artery diameter located anywhere in the culprit artery.
