Coronary angioplasty in a case of quadriostial origin of coronary arteries from right aortic sinus.

We report a case in which all three coronary arteries were originating from the right aortic sinus via separate ostia, and angioplasty of the normally arising right coronary artery was performed. In addition, the conal artery was also originating separately from same sinus, actually leading to a quadriostial origin of the coronaries. A combination of anteroaortic septal course of the left anterior descending artery and retroaortic course of left circumflex artery is an unusual coronary anomaly and was noted in this case.
