In this article, developments in the technique of percutaneous transluminal coronary angioplasty (PTCA) since its introduction in 1977 as well as current trends and likely future directions of the technique are outlined. Over the last 6 or 7 years, there has been a dramatic widening of the applications PTCA to include patients with complex anatomic lesions and adverse clinical features. Despite the large percentage of such difficult cases currently presenting for PTCA, an initial success rate in excess of 90% is achieved. Increased operator experience and continuing refinements in angioplasty technology are important factors in this continuing success of PTCA. Early restenosis remains the major drawback of the technique; this complication is usually treated by repeat PTCA. Available information indicates that the long-term outcome of patients after successful PTCA is excellent, with a low incidence of late restenosis and progression of disease. The relative efficacy of PTCA and coronary bypass surgery in patients with multivessel disease is, at present, uncertain.
本文概述了经皮腔内冠状动脉成形术（PTCA）自1977年引入以来该技术的发展情况，以及该技术当前的趋势和未来可能的发展方向。在过去的6、7年里，PTCA的应用范围急剧扩大，已包括具有复杂解剖病变和不良临床特征的患者。尽管目前接受PTCA治疗的此类疑难病例占很大比例，但初始成功率仍超过90%。术者经验的增加和血管成形术技术的不断改进是PTCA持续取得成功的重要因素。早期再狭窄仍然是该技术的主要缺点；这种并发症通常通过再次PTCA治疗。现有信息表明，成功实施PTCA后患者的长期预后良好，晚期再狭窄和疾病进展的发生率较低。目前，PTCA与冠状动脉搭桥手术在多支血管病变患者中的相对疗效尚不确定。
