 (A) Left anterior oblique left main coronary artery angiogram showing a hypoplastic distal left anterior descending coronary artery (arrows). Septal branches are well developed and supply the basal part of the interventricular septum. In contrast, no diagonal branches are seen on the anterolateral free wall of the ventricle and no posterior branch issuing from the left circumflex artery. (B) Lateral view angiogram showing hypoplastic right coronary artery without posterior descending artery and no supply to the basal part of interventricular septum (arrows).
