Figure 1 (A) SPECT images obtained before (preR), during (R) and 2 days after (postR) PTRA in a patient with a lesion of the left anterior descending artery (LAD) and a previous inferior myocardial infarction. Sagittal long-axis views are displayed indicating a transient apical perfusion defect. (B) Polar maps of the left ventricle of the patient shown in (A). Relative tracer uptake values in the LAD territory before (preR), during (R) and two days after (postR) PTRA are depicted. In regions with significantly reduced perfusion, perfusion values are highlighted. *Region with the maximal perfusion reduction during the intervention.
