The argon laser catheter was demonstrated in five human patients from Sept. 17-21, 1983, in Toulouse, France. All five had 75-95% stenotic lesions in main coronary arteries due to arteriosclerotic plaque. There were two left anterior descending and three right coronary arteries. All patients were undergoing coronary artery bypass graft surgery.
