Paper Abstract

Transmyocardial laser revascularization was found to be a new emerging technique for the treatment of end-stage coronary artery diseases. In our study, comparison of the ablation effect of the various infrared solid state laser radiations on myocardial tissue was studied. Tm:YAG, CTH:YAG, CTE:YAG and Er:YAG lasers with the fiber and waveguide delivery systems were prepared and the ablation coefficients for the radiation 2.01 micrometers (Tm:YAG), 2.1 micrometers (CTH:YAG), 2.67 micrometers (CTE:YAG) and 2.94 micrometers (Er:YAG) interacting with myocardial tissue were measured. From the histological examination follows that the channels ablated by Er:YAG laser radiation are without any thermal damage of the surrounding tissue and with the minimal mechanical injury, therefore Er:YAG laser could be considered as a good candidate for the TMLR.
