Abstract

Management of myocardial ischemia by direct myocardial revascularization with lasers has been attempted in the past. Although this procedure has met with considerable controversy, its original hypothesis was based on the assumption that miniscule laser channels could provide a means by which left ventricular blood could nourish ischemic myocardium. However, although numerous experimental studies have demonstrated a decrease in size, its application in a clinical setting has experienced limited success. In this present study, the issue of regional myocardial contractility was assessed in an acute ischemic canine model. In addition, the H- Yag laser was evaluated for its potential in revascularizing the myocardium and its capability of maintaining regional contractility.
