Over a 2-year period 33 patients with symptomatic stenosis (greater than 75%) of the left main coronary artery underwent aortocoronary bypass. Intra-aortic balloon counterpulsation was used preoperatively in only two patients as a therapeutic measure for medically unstable angina. There were no operative deaths. Follow-up study 3 to 27 months (mean 13.3 months) after operation revealed one death. Twenty-two patients were free of pain. The authors conclude that aortocoronary bypass surgery for severe stenosis of the left main coronary artery can be safely accomplished, without prophylactic use of intra-aortic balloon counterpulsation in the majority of cases, with an acceptable operative mortality and morbidity.
在两年期间，33例有症状的左主冠状动脉狭窄（大于75%）患者接受了主动脉冠状动脉搭桥术。术前仅2例患者使用主动脉内球囊反搏作为治疗药物难以控制的心绞痛的措施。无手术死亡病例。术后3至27个月（平均13.3个月）的随访研究显示有1例死亡。22例患者无痛。作者得出结论，对于左主冠状动脉严重狭窄，主动脉冠状动脉搭桥手术在大多数情况下无需预防性使用主动脉内球囊反搏即可安全完成，手术死亡率和发病率可接受。
