Coronary artery anomalies: classification and electrocardiogram-gated multidetector computed tomographic findings.

Congenital coronary artery anomaly is an uncommon condition. Most of these anomalies are clinically silent without associated myocardial ischemia, but some of those may cause significant myocardial ischemia or infarction. Multidetector computed tomography with electrocardiogram (ECG)-gating has a faster volume coverage and higher spatial and temporal resolution and is a noninvasive and accurate technique that can be used to show these kinds of anomalies. Understanding the computed tomographic findings of various coronary artery anomalies is important for obtaining an accurate diagnosis and for formulating an optimal patient treatment plan.
