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.
摘要
约85%的人后降支动脉（PDA）起源于右冠状动脉（RCA）；仅10%至15%的人后降支动脉起源于回旋支动脉。我们报告了一例罕见的后降支动脉起源于左前降支动脉（LAD）分支的病例。后降支动脉在到达后室间沟之前穿过室间隔。
