Fig 1 Left ventricle short-axis images of first-pass perfusion during dipyridamole stress at baseline (upper left) and at 6 months after transmyocardial laser revascularization plus stem-cell therapy (lower left). Arrows (upper left) indicate an almost circumferential, subendocardial dark rim compatible with myocardial ischemia, which is not seen at follow-up (lower left). Myocardial delayed enhanced images (upper/lower right) revealed an anteroseptal myocardial infarction (arrow) equally seen in both exams.

Fig 2 End-systolic frame of left ventricle short-axis (left), 4-chamber (middle) and 2-chamber (right) views of cine magnetic resonance imaging are depicted at baseline (top) and at 6 months after the procedure (bottom). Arrows indicate the left ventricle mid anterior (left), basal anterior (middle), and anterolateral (right) segments that showed the most evident improvement in myocardial contractility defined by an increase in the end-systolic wall thickness at 6 months. Overall left ventricular functional improvement was mainly due to an increase in stroke volume (B = 48 mL versus 6 months = 77 mL), and a decrease in end-systolic volume (B = 129 mL versus 6 months = 101 mL), since there was no change in end-diastolic volume (B = 177 mL versus 6 months = 178 mL).
