Effects of Transmyocardial Revascularization with Frequency-double Nd:YAG Laser on Myocardial Blood Flow of Acute Infarcted Myocardium in Canine
Objective The study was aimed to assess the effects of experimental transmyocardial revascularization with frquency- double Nd:YAG(KTP) laser (TMLR) on myocardial blood flow in zcute myocardial infarction2 -Smonth. Methods: Left thoracotomy was performed in 12 adult mongrel dogs. The medius of the left anterior descending artery (LAD) was ligated to creat the acute myocardial infarction. TMLR was performed with KTP laser in the acute infarcted LAD territory in TMLR group (n=6) and without any treating in control group (n=6). Myocardial perfusion imaging with 99m Tc - sestamibi SPECT was performed 2 - 3months after acute myocardium infraction both groups. Results; Myocardial perfusion SPECT imaging showed radioactivity deficit or decreasing of ra-diodistribution in anterior, interventricular septum and aex in both groups. There was no significant difference on the myocardium scores of radiodistribution between two groups. Conclusion: TMLR with KTP laser didn't improve myocardium perfusion 2 - 3 months after TMLR in acute myocardial infraction.
