Abstract

The most common an anomalous right coronary artery (RCA) is that originates from the aortic trunk of ascending artery or left sinus of Valsalva. Herein, we presented five extremely rare cases of anomalous RCA detected incidentally during routine coronary angiography. The first two cases are the anomalous RCA arising separately from the left main stem and proximal of left anterior descending artery (LAD), the third case is the anomalous artery originating from the distal of left circumflex coronary (LCX) artery, and the last two cases are the anomalous RCA deriving from the left sinus of Valsalva.
