    • Abstract:
      26 dogs were devided into 3 groups. Selected left coronary artery branches of all dogs were ligated to make the models of myocardial infarction. The control group of 10 dogs received ligation of selected coronary artery branches(L group) only. Eight dogs were revascularized by Nd:YAG laser (LL group), and 8 dogs were revascularized and covered with pedicled omentum. All dogs were monitored by ECG, cardiac output, fractional 86Rb uptake and histological examination. The results showed that laser channels can perfuse ischemic myocardium and recover myocardial circulation to improve cardiac function immediately. However, the laser channels were closed after 4 weeks by clot, fibrosis and scarring which caused by thermal damage of Nd:YAG laser. The late result of laser myocardial revascularization with pedicled omentum graft is more better in perfusing myocardium and improving cardiac function than sole laser myocardial revascularization.
