Transmyocardial laser revascularization

The clinical experience with transmyocardial laser revascularization indica tes that angina is relieved significantly, perfusion and treadmill toleranc e are improved and hospital admissions are decreased. The exact mechanism f or a laser revascularization linked improvement is still unknown. Transmyoc ardial laser revascularization should be used only in highly selected cases when conventional methods fail to improve patients symptoms. Further evalu ation of the efficacy of the new indirect revascularization method in clini cal (larger multicenter trials) and experimental studies to elucidate the m echanism of TMLR is warranted. Experimental long-term studies to explain th e mechanism are in progress.
