A 65-year-old man with left ventricular ejection fraction (LVEF) of 16% successfully underwent coronary artery bypass grafting (CABG). CABG used to be contraindicative for patients with LVEF below 20%. However, such patients are recently involved to indication of CABG if viability of the myocardium is proved. We consider CABG is indicated for a patient who keeps a sufficient cardiac output despite a low level of LVEF. Intraaortic balloon pumping which was started immediately after the induction of anesthesia was effective. Only eight patients with LVEF below 20% have undergone CABG in Japan. Thus, we reported our patient with some discussion on operative indication and perioperative management.
一名左心室射血分数（LVEF）为16%的65岁男性成功接受了冠状动脉旁路移植术（CABG）。过去，LVEF低于20%的患者进行CABG被视为禁忌。然而，近来如果证明心肌存活，这类患者也被纳入CABG的适应证范围。我们认为，对于LVEF水平较低但仍能维持足够心输出量的患者，CABG是适用的。麻醉诱导后立即开始的主动脉内球囊反搏是有效的。在日本，仅有8例LVEF低于20%的患者接受了CABG。因此，我们报告了该病例，并对手术适应证和围手术期管理进行了一些讨论。
