LAD arising from the left sinus of Valsalva was short and gave rise to one septal branch, a little intermedius branch, and one diagonal branch [Figure 1].
Circumflex artery (LCX) is aplastic, as shown in the left caudal angiographic projection

The left circumflex artery (LCX) was aplastic [Figure 2] and the right coronary artery (RCA) was dominant and normal in origin and course [Figures 3 and 4].

The left circumflex artery (LCX) was aplastic [Figure 2] and the right coronary artery (RCA) was dominant and normal in origin and course [Figures 3 and 4].
Long LAD arises from the right sinus of Valsalva with a separate ostium, different from RCA. This LAD is longer than the first, runs on the right ventricle, and gives rise to septal and diagonal branches, supplying the mid and distal territories of septal, anterior, lateral wall, and apex

A second LAD was seen arising from the right sinus of Valsalva, with a third ostium different from RCA [Figure 5].
Overlapping Figures 1 and 5, we can see the entire course of LAD along interventricular sulcus to the apex

This second LAD was long, run over the right ventricle, and gave rise to septal and diagonal branches, supplying the mid and distal territories of septal, antero-lateral wall, and apex [Figure 6].
