Separate origin of all three coronary arteries from a single sinus of Valsalva.

We present a case of a 6-year-old boy with a double outlet right ventricle where the independent origin of all three coronary arteries from a single sinus of Valsalva was incidentally detected on CT angiography. The case highlights the role of CT angiography in identifying coronary arterial anomalies in the setting of complex congenital heart diseases.
