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).
Examples
An 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.
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.
Shown below are an animated image and a static image depicting an aneurysm in the left coronary artery. Outlined in yellow in the image on the right is the localized aneurysm which is a dilatation of the coronary artery segment >1.5 times the diameter of the adjacent segments on the LCA.
