Anomalous origin of posterior descending artery from left anterior descending artery with unusual intraseptal course

S P Singh et al. J Thorac Imaging. 1994 Fall.

Abstract

The posterior descending artery (PDA) arises from the right coronary artery (RCA) in approximately 85% of people; only in from 10 to 15% does it arise from the circumflex artery. We report an unusual case of origin of the PDA from a branch of the left anterior descending artery (LAD). The PDA passed through the interventricular septum before it reached the posterior interventricular groove.
