Anomalous origin of the left coronary artery from the right sinus of Valsalva with separate ostia and inter-arterial course: MDCT angiography depiction.

We describe a case of anomalous left coronary artery origin from the right coronary sinus with separate ostia of right and left coronary arteries detected by 128-slice computed tomography (CT) coronary angiography. Apart from separate ostia, the left coronary artery had inter-arterial course between the aorta and the pulmonary trunk, also called as a malignant course.
