Figure 1: (a) Post-stress-gated SPECT images showed a fixed perfusion defect involving entire anterior segment (small arrow) and reversible perfusion defect in lateral segment (bold arrow) indicating a large LAD territory infarct with moderate reversible ischemia in lateral segment of left ventricle. (b) Coronary angiogram confirmed left main coronary artery ostial occlusion, with retrograde collateral supply from dilated right coronary artery
