The 16-slice MDCT showed the LAD, LCx, and RCA originating separately from the right coronary sinus [Figure 1].
56-year-old male patient admitted with chest pain diagnosed with three coronary arteries originating separately from the right coronary sinus. (a) Volume-rendered three-dimensional image (VR-3D) shows the left anterior descending artery (LAD) originating from the right coronary sinus (short white arrow) and passing between the aorta (Ao) and the pulmonary artery (Pa) (open arrow: right coronary artery). (b) MDCT image shows LAD diagonal branch with myocardial bridging (arrowheads).

The LAD showed interarterial course passing between the aorta and the pulmonary artery [Figure 2a]. The diagonal branch of the LAD showed myocardial bridging [Figure 2b]. The RCA followed a normal course [Figure 2b].
