During the period between October 1980 and December 1982, percutaneous transluminal angioplasty of stenosed aortocoronary bypass grafts was attempted 44 times in 31 patients who had developed disabling angina pectoris four months to seven years after coronary bypass surgery. The primary success rate was 93%. Two (4.5%) patients developed myocardial infarction related to the procedure. No emergency aortocoronary bypass surgery was required and there was no mortality. Although the primary success rate was high, the incidence of recurrence after one or more angioplasties was 50%. Despite this recurrence rate the condition of 10 of the first 16 (62%) patients was clinically improved after a mean follow up of 26 months.
在1980年10月至1982年12月期间，对31例在冠状动脉搭桥手术后4个月至7年出现致残性心绞痛的患者，尝试进行了44次经皮腔内血管成形术治疗狭窄的主动脉冠状动脉搭桥移植血管。初次成功率为93%。两名（4.5%）患者发生了与该手术相关的心肌梗死。无需进行急诊主动脉冠状动脉搭桥手术，也没有死亡病例。尽管初次成功率很高，但在进行一次或多次血管成形术后的复发率为50%。尽管有这个复发率，但在前16例患者中的10例（62%）在平均随访26个月后临床状况得到改善。
