Congenitally Absent Left Circumflex Artery.

: Congenital coronary anomalies are uncommon with rarest being absent left circumflex artery (LCX) having prevalence of 0.003%. We report a case of a 68 year old male having acute coronary syndrome and left ventricular dysfunction whose coronary angiogram showed an absent LCX with super dominant right coronary artery (RCA). Precise morphological evaluation is needed for best suited management strategy.
