Independent origin of anterior interventricular and left marginal arteries from the left posterior aortic sinus

We present a unique, unreported variation of the left coronary artery. During dissection classes for first-year medical students, we observed the absence of left coronary artery in an adult male cadaver aged approximately 78 years. The left aortic sinus was dilated and it gave origin to anterior int...

description We present a unique, unreported variation of the left coronary artery. During dissection classes for first-year medical students, we observed the absence of left coronary artery in an adult male cadaver aged approximately 78 years. The left aortic sinus was dilated and it gave origin to anterior interventricular and left marginal arteries independently. Left marginal artery was large and the circumflex artery arose from it. There were two independent opening for anterior interventricular and left marginal arteries in the left posterior aortic sinus. No variations were found in the origin and branching pattern of right coronary artery and the walls and chambers of the heart.
