Serial axial sections of heart demonstrating absent left circumflex artery (open arrow) in the upper part of left atrioventricular groove (arrow) with left main coronary artery (LM) continuing as left anterior descending artery (LAD). Good-sized right posterolateral ventricular branch (RPLV), crossing the crux of the heart and then ascending into the inferior part of atrioventricular groove (double arrows). Several tortuous branches arising from RPLV (curved arrow) perfusing postero-lateral and lateral walls of the heart (in the usual vascular territory of LCX artery)

The CT revealed non visualised left circumflex coronary artery, likely congenitally absent (Figures 1a and 2a). The right coronary artery was good sized (Figures 1b, and 2b) with a tortuous course. The right posterolateral ventricular branch (RPLV) arising from the right coronary artery was good sized (Figure 2b) and extended leftwards, crossing the crux of the heart and then ascending into the inferior part of atrioventricular groove (Figure 1). Several tortuous branches were seen arising from it perfusing postero-lateral and lateral walls of the heart (in the usual vascular territory of LCX artery) (Figures 1 and 2).
Volume rendered images of heart demonstrating absent left circumflex artery (open arrow) in the upper part of left atrioventricular groove (arrow) with left main coronary artery (LM) continuing as left anterior descending artery (LAD). Good-sized and tortuous right coronary artery (RCA). Good-sized right posterolateral ventricular branch (RPLV) arising from the right coronary artery and extended leftwards, crossing the crux of the heart and then ascending into the inferior part of atrioventricular groove (double arrows). Several tortuous branches arising from RPLV (curved arrow) perfusing postero-lateral and lateral walls of the heart (in the usual vascular territory of LCX artery).
