Unobstructed blood flow predicts TMLR outcome

Kaplan-Meier curves show that survival after transmyocardial laser revascularization (TMLR) is strongly affected by the overall anatomic myocardial perfusion index score (AMP); patients with a score of 1, which indicates unobstructed blood flow to a major vessel in at least one vascular territory, had a lower mortality than those who did not have adequate blood flow to any region (AMP score = 0).
