Aberrant origin of coronary arteries is a not uncommon entity found on cardiac catheterization, at the time of surgery, and on post mortem examination. We present two cases of origin of a right ventricular (or atypical large conus) branch of the right coronary artery originating from a separate ostium in the right coronary cusp, which to our knowledge has been only rarely previously described. We feel that this may be a relatively frequent coronary varient that has important implications regarding patient assessment and care.
冠状动脉异常起源是一种在心脏导管检查、手术时及尸检中并不罕见的情况。我们报告两例右冠状动脉的右心室（或非典型大圆锥）分支起源于右冠状动脉瓣叶单独开口的病例，据我们所知，此前仅有极少的相关描述。我们认为这可能是一种相对常见的冠状动脉变异，对患者评估和治疗具有重要意义。
