Abstract

Introduction: Transmyocardial Laser Revascularization (TMLR) has a good potential in treatment of some disease however the mechanism of action is not well known. Most probably channel's geometrical shape and thermal damage have an important role in its function. Unfortunately there have been significant discrepancies in the follow up results of TMLR.Materials & Methods: The Nd: YAG laser beam, with powers of 85w and 105w was delivered to left ventricle of sheep heart through a 500mm fiber optic. The fiber penetration speed into the tissue were 1.2mm/s and 2.4mm/s. Results and Discussion: All the channels had elliptical cross sections. The reduction of dimensions and surfaces of channels cross sections were statistically significant when the laser power increased and the fiber speed was kept constant. Channels cross sections were decreased by increasing of the fiber speed while the laser power was kept constant. Under the above conditions the differences in CHANNEL'S CROSS-SECTIONS were not statistically significant.
