CT angiogram for assessment of coronary anatomy. Cardiac CT revealed no significant coronary artery disease but did show a left main coronary artery with an anomalous origin off of the right sinus of Valsalva with subsequent intraseptal course (Figure 1).
Left anterior oblique view of left main coronary artery with an anomalous origin off the right sinus of Valsalva with intraseptal course.

CT was completed. Cardiac CT showed the left main to have an anomalous takeoff from the right coronary cusp with a course between the great vessels (Figures 4 and 5).
Three dimensional reconstruction exhibiting the interarterial course of the left main coronary artery as presented in Case 2.
