The increased number of patients with coronary artery disease has been obviously recognized and several kinds of operations have been widely performed in Japan. Especially, coronary artery bypass grafting (CABG) for these patients has been a popular surgical intervention. Among these patients there are a few cases for whom CABG could not be carried out, because of diffuse stenoses and small caliber coronary arteries. The purpose of this study was proposed to an alternative method of myocardial revascularization by high energy co2 laser for treatment in these severely ill patients with coronary artery disease. The feasibility of myocardial revascularization from the left ventricular cavity through channels newly created by laser was evaluated in this study. This method was based on the phenomenon that the laser beam could produce fine laser holes and myocardial fibrosis would not occur even over the long term. There are many collateral channels between coronary arteries and veins, or myocardial sinusoids in the myocardium. Therefore, if laser holes in the myocardium were clearly produced, the ischemic myocardium could be apparently nourished by arterial blood from the left ventricular cavity through newly created channels as well as other collateral channels in the myocardium.
