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 μm (Tm: YAG), 2.1 μm (CTH: YAG), 2.67 μm (CTE: YAG) and 2.94 μm (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.
