Technical success in percutaneous transluminal coronary angioplasty (PTCA) is a function of patient selection, operator experience, and the capabilities of the angioplasty equipment employed. When unsuccessful PTCA occurs, it is the result of one of several factors: (1) a failure to cross the stenosis; (2) a failure to dilate the stenosis; (3) an ischemic complication; or (4) a late recurrence of the anginal syndrome. In this paper, we discuss the relative frequency of these types of failure, and the ways in which improvements in technique and/or equipment may be employed to improve the chance of a successful procedure.
经皮腔内冠状动脉成形术（PTCA）的技术成功取决于患者的选择、术者的经验以及所使用的血管成形术设备的性能。当PTCA失败时，是由以下几个因素之一导致的：（1）未能穿过狭窄部位；（2）未能扩张狭窄部位；（3）缺血性并发症；或（4）心绞痛综合征的晚期复发。在本文中，我们讨论了这些类型失败的相对发生率，以及可采用改进技术和/或设备的方法来提高手术成功的几率。
