A 50-year-old woman presented to our hospital with Canadian Cardiovascular Society grade III angina of 4 months duration. Coronary angiography of the patient showed the absence of left main coronary artery from the left coronary sinus. There was a single right coronary artery (RCA) with a super dominant course from right coronary sinus. It also showed a left main coronary and left anterior descending artery arising separately from proximal RCA, with retroaortic and prepulmonic course, respectively. There was another independently arising small septal branch from the proximal RCA that supplied the proximal interventricular septum. The patient was managed with optimal medical therapy and had symptomatic relief.
