Coronary CTA demonstrated an anomalous left anterior descending artery (LAD) arising from the same ostium with the right coronary artery, which coursed downwardly along the interventricular sulcus, and another LAD arising from the left main coronary artery, which spread to the anterior wall of the left ventricle toward the left ventricular apex [Figures 1 and 2].
The 3-dimensional (3D) volume rendered image demonstrates both of the left anterior descending arteries (LAD), one originating from the left main coronary artery and the second anomalous one from the right side and spreading to the anterior wall of the left ventricle toward the left ventricular apex.

The segmented 3D image demonstrates both the left anterior descending arteries (LAD), their origin and course.

However, the anomalous LAD was coursing between right ventricular outflow tract and aorta which should be considered to be critical because of the potential to provoke myocardial ischemia or even sudden cardiac death [Figure 3].
