| Abstract: | Background:Transmyocardial laser revascularization (TMR) has been established with the carbon dioxide(CO 2) and Ho:YAG Laser,but it is unknown whether Frequencydouble Nd:YAG Laser can be used for transmyocardial laser revascularization.We compare effects of KTP Frequencydouble Nd:YAG Laser and Ho:YAG Laser on the isolated porcine heart. The aim is to study the feasibility that Frequencydouble Nd:YAG Laser be used for transmyocardial laser revascularization. Methods: On fresh porcine left ventricular myocardium, We created channels in different energy with KTP Frequencydouble Nd:YAG Laser and Ho:YAG Laser,then examined the histologic changes of the laser channels. Results:Both KTP frequencydouble Nd: YAG laser and Ho: YAG laser can creat channel,but the channels creating by frequencydouble Nd:YAG laser are straighter than by Ho:YAG laser. The thermal jury in frequencydouble Nd:YAG laser group is smaller than in Ho:YAG laser group. Conclusion: It is hopeful that frequencydouble Nd: YAG laser be used for transmyocardial laser revascularization. |
