At the present time all laser coronary angioplasty systems in use are investigational devices awaiting FDA approval. Preliminary results in human trials of several coronary laser angioplasty systems have been reported and appear encouraging. The technological achievement of delivering laser energy to the coronary circulation and opening occluded arteries has been accomplished. The much more difficult question of determining which patients, if any, should be offered this very expensive technology remains to be answered.
目前，所有正在使用的激光冠状动脉成形术系统都是等待美国食品药品监督管理局（FDA）批准的研究性设备。已有数种冠状动脉激光成形术系统的人体试验初步结果被报道，且这些结果看起来令人鼓舞。将激光能量输送到冠状动脉循环并开通闭塞动脉这一技术成果已经实现。然而，一个更棘手的问题是，确定哪些患者（如果有的话）应该接受这项极为昂贵的技术，这一问题仍有待解答。
