Between April and December 1983 100 transluminal coronary dilatations in 98 patients were performed using new steerable balloon catheter systems. The primary success rate (diameter enlargement greater than 20%) overall was 87%, in stenoses of the anterior interventricular branch 88.1% (59 out of 67 interventions), in stenoses of the right coronary artery 88.9% (16 out of 18), and in circumflex branch stenoses 84.6% (11 out of 13). Within the first 50 interventions the success rate was 80%. Among the second 50 cases it was improved to 94%, mainly due to the increasing experience of the investigators. Emergency bypass operations had to be performed in two patients in whom coronary vascular occlusion had occurred. No patient died and in only one a small infarction occurred, probably due to occlusion of a side branch with an increase of creatine kinase to a maximum of 120 U/l. These figures show that steerable balloon systems clearly improve the primary success rate despite broadening of indications and diminish serious complications.
1983年4月至12月期间，使用新型可操纵球囊导管系统对98例患者进行了100次经腔冠状动脉扩张术。总体而言，初次成功率（直径增大超过20%）为87%，前室间支狭窄的成功率为88.1%（67次干预中有59次成功），右冠状动脉狭窄的成功率为88.9%（18次中有16次成功），回旋支狭窄的成功率为84.6%（13次中有11次成功）。在前50次干预中，成功率为80%。在随后的50例病例中，成功率提高到了94%，这主要归功于研究人员经验的增加。有两名发生冠状动脉血管闭塞的患者不得不接受紧急搭桥手术。没有患者死亡，只有1例发生了小面积梗死，可能是由于一个侧支闭塞，肌酸激酶最高升至120 U/l。这些数据表明，尽管适应症有所扩大，但可操纵球囊系统明显提高了初次成功率，并减少了严重并发症的发生。
