Patient Data
CT findings: Dominant left circulation, ectatic LMCA with no significant stenosis.
LAD - long artery that reaches and wraps around the apex, it supplies two diagonal branches (the D2 is a large bifurcating artery) and many septal perforators, the proximal, and mid LAD is ectatic as both mounts to 7 mm in diameter. No significant stenosis was noted.
LCX - dominant ectatic artery that supplies a large ectatic OM branch, PLA and PDA; No significant stenosis
RCA - a non-dominant artery that ends at the acute margin of the heart, normal caliber and free of significant stenosis.
Case Discussion
Coronary arterial ectasia is an uncommon finding. Most of the patients are asymptomatic and in most of the cases, coronary ectasia is detected incidentally.
