Percutaneous transluminal coronary laser angioplasty is still undergoing clinical trials. The laser systems employed are of the pulsed type - for the most part the excimer laser - which are more effective for removing calcified plaque and have a lower complication rate than continuous wave lasers. While the long-term results are comparable with those achieved with balloon dilatation, the primary success rate of laser angioplasty alone is not yet up to the standards of balloon angioplasty. Improvements may be expected through the further development of catheter systems and the introduction of new techniques with more accurate and specific ablation of arteriosclerotic plaques.
经皮腔内冠状动脉激光血管成形术仍在进行临床试验。所使用的激光系统为脉冲型——大部分是准分子激光——对于去除钙化斑块更有效，且并发症发生率低于连续波激光。虽然长期结果与球囊扩张术相当，但单纯激光血管成形术的主要成功率尚未达到球囊血管成形术的标准。通过导管系统的进一步发展以及引入能更精确、更特异性地消融动脉粥样硬化斑块的新技术，有望取得改进。
