Percutaneous transluminal coronary angioplasty (PTCA) is a well-accepted procedure used in therapy for coronary artery stenosis. It is a delicate procedure depending upon the operator's experience and technique. Major efforts have been directed toward improving such performance. This is a report of our growing experience accumulated over the last eight years. From July 1983 to December 1990, 893 cases of coronary artery disease with a total of 1111 procedures received PTCA in this hospital. The success rate in dilatation increased year by year; to peak in 1990 (94%). PTCA was performed in 447 cases of single vessel disease; 310 cases of double vessels disease; and 136 cases of triple vessels disease. Dilated coronary artery lesions included left anterior descending artery, 637 (64%), right coronary artery, 198 (20%), and left circumflex artery 157 (16%). More than one procedure was undertaken in 178 patients, and about 20% patients had repeated PTCA. Major complications such as acute myocardial infarction developed in 3.0%. One point one percent had emergency surgery and the mortality rate was 1.8%. The majority of cases were followed up and appeared well after successful angioplasty. In conclusion, PTCA is an valuable procedure for treatment of critical coronary artery stenosis, with acceptable complications.
经皮腔内冠状动脉成形术（PTCA）是治疗冠状动脉狭窄的一种广泛接受的方法。这是一个依赖于操作者经验和技术的精细操作。人们已经做出了重大努力来提高这种操作的性能。这是我们过去八年积累的不断增长的经验报告。从1983年7月到1990年12月，本院共对893例冠心病患者进行了1111次PTCA手术。扩张成功率逐年提高，在1990年达到峰值（94%）。PTCA用于治疗单支血管病变447例，双支血管病变310例，三支血管病变136例。扩张的冠状动脉病变包括左前降支637例（64%）、右冠状动脉198例（20%）和左旋支157例（16%）。178例患者接受了不止一次手术，约20%的患者进行了重复PTCA。主要并发症如急性心肌梗死的发生率为3.0%。1.1%的患者接受了急诊手术，死亡率为1.8%。大多数病例进行了随访，血管成形术成功后情况良好。总之，PTCA是治疗严重冠状动脉狭窄的一种有价值的方法，并发症可以接受。
