Anomaly Of Right Coronary, Lad, And Cx Arteries Originating From Right Sinus Valsalva

Single coronary artery is observed in approximately 2-4% of all coronary artery anomalies. In our case, 48 years old female patient had exercise-induced angina pectoris and fatigue. After her exercise electrocardiogram revealed ST depression during 9 mets, we demonstrated a single coronary artery as an extremely rare anomaly of coronary artery in which there was no original left main artery as well as right coronary artery, left anterior descending and circumflex arteries were originated from right sinus Valsalva. On medical treatment with beta blocker, her symptoms had recovered. This type of coronary anomalies is very infrequent and may be a reason of sudden death.
