Figure 1. Left coronary angiogram in right anterior oblique (RAO) cranial view: no circumflex artery is demonstrated.
Figure 2.
Figure 2. Left coronary angiogram in RAO caudal view: showing absent left circumflex (LCX) and long left main coronary artery.
Figure 3.
Figure 3. Right coronary angiogram in left anterior oblique (LAO) view: showing super-dominant RCA with large posterolateral branches supplying the area of left circumflex territory.
Figure 4.
Figure 4. Right coronary angiogram in RAO cranial view: showing a super-dominant RCA with large posterolateral branches perfusing the posterolateral and lateral walls of the heart (usually supplied by the left circumflex artery).
Figure 5.
Figure 5. Aortic root angiogram in LAO caudal view: showing no evidence of the anomalous origin of left circumflex artery.
Figure 6.
Figure 6. Different views of three-dimensional computed tomography scan shows absent left circumflex artery in the atrioventricular groove with single left anterior descending artery with super-dominant right coronary artery with a good-sized right posterolateral ventricular branch crossing the crux of the heart and then ascending into the inferior part of atrioventricular groove and supplying the posterolateral and lateral walls of the heart (usually supplied by the left circumflex artery).
