FIGURE 6. Relatively unremarkable rest-stress myocardial perfusion images with a significant decrease in LVEF during peak stress. Patient also had CT coronary angiogram immediately after PET study that demonstrated left dominant anatomy and severe calcified left main disease (bottom right; inset is cross section through left main artery) that was subsequently confirmed by catheter coronary angiography (bottom left). He underwent coronary artery bypass surgery. LVEDV = left ventricular end-diastolic volume; LVESV = left ventricular end-systolic volume; LM = left main coronary artery; RA = right atrium.
