Abstract

Lasers have been recently utilized in the field of cardiovascular surgery through the world.Most of them are fundamental works concerning laser angioplasty.Since 1980 we have started three scientific studies as follows. That is, 1) myocardial revascularization by laser, 2) vascular anastomosis, 3) laser angioplasty.On the basis of excellent experimental studies in these fields. lasers were clinically applied with safety.The numbers of the patients for whom lasers were utilized reached to 185 cases.They consisted of one case with myocardial revascularization, 110 cases with laser vascular anastomosis including coronary artery bypass grafting of 13 cases and 74 cases with laser angioplasty including intraoperative coronary angioplasty of 10 cases.Twenty-four cases of them received laser applications, because of angina pectoris and myocardial infarction.Characteristics of lasers were clearly recognized even in our clinical experience. Indications, techniques and long-term results of laser applications in cardiovascular surgery were reported in detail.
