A completely absent LCx was observed, which was associated with multiple enlarged diagonal branches of the left anterior descending artery (LAD) to supply the lateral wall of the left ventricle (Figure 1).
Inferior view of three-dimensional computed tomography scan shows superdominant right coronary artery (large arrow) to supply posterior wall (small arrow).
