title: Dissociation between improvement in angina pectoris and myocardial perfusion after transmyocardial revascularization with an excimer laser.
abstract: Xenon chloride excimer laser transmyocardial revascularization significantly reduced angina in all patients and increased regional myocardial perfusion in most patients; however, there was no correlation between symptomatic improvement and flow improvement. Patients' symptomatic improvement preceded improved perfusion by several months.
