Coronary artery aneurysm is an abnormal dilatation of part of the coronary artery.


It is often found coincidentally on coronary angiography.[1]


Acquired causes include atherosclerosis,[2] Kawasaki disease[3] and coronary catheterization.

It can also be congenital.[4][5]


Generally, it has a good prognosis.[1] In Kawasaki's disease, untreated, there is a 1-2% death rate, from cardiac causes.
