A unique case of anomalous coronary origin detected by 64-row multislice computed tomography coronary angiography.

The anomalous origin of the left coronary artery from the right sinus of valsalva is an anatomical abnormality that is usually associated with myocardial ischaemia and sudden death. We report on a case in which three different diagnostic techniques were used to find the cause of the ischaemic symptoms in a patient whose left coronary artery originated anomalously in the right sinus of valsalva and followed a course between the aorta and the pulmonary trunk. The techniques were treadmill exercise test for ischaemia, conventional angiography, which was used for the initial diagnosis, and 64-row multislice computerised tomography, used to determine the anomalous course of the artery.
