Despite the increasing enthusiasm surrounding endovascular techniques for treating peripheral vascular disease, chronic total occlusions (CTOs) continue to pose significant challenges to interventionists. The search for devices to improve acute procedural success and long-term results has been difficult. The theoretical advantage of plaque ablation or vaporization, especially in long, diffuse, and occlusive disease, remains appealing. Excimer laser angioplasty has been studied since the late 1980s for peripheral vascular disease. However, widespread adoption has been limited by misunderstanding data from various laser studies in which catheters of different wavelengths were generalized under the generic acronym of “laser.” This article describes the currently known data on the excimer (xenon chloride), 308-nm...
