[A new technique for transmyocardial laser revascularization].

Objective: To investigate the effects of traditional transmyocardial laser revascularization (T-TMLR) and non-transmural myocardial laser revascularization (N-TMLR) on myocardial ischemic and necrotic areas and angiogenesis.

Methods: In 30 rabbit models, Evans blue -TTC staining and HE staining were used for measuring ischemic and necrotic areas and observing angiogenesis.

Results: The ischemic areas in the MI + T-TMLR (30.
