A 70-year-old male was admitted for acute postero-inferior myocardial infarction. In cardiac catheterization one month later, there was narrowing of the distal left circumflex artery and the aneurysm of the postero-inferior wall of the left ventricle. The echocardiogram strongly suggested the pseudoaneurysm of the left ventricle. At operation, a large postero-inferior aneurysm was densely adherent to the pericardium. After cardiopulmonary bypass was established, the aorta was cross-clamped and cold cardioplegia was infused, the aneurysm was opened without excision of it. There was a 4 cm by 5 cm defect in the postero-inferior wall of the left ventricle, which communicated with the cavity of the aneurysm. The defect was closed with a patch. Pseudoaneurysm of the left ventricle was diagnosed by histological examination. The postoperative course was uneventful and he discharged on 29th day after surgery.
一名70岁男性因急性后下壁心肌梗死入院。一个月后进行心脏导管检查时，发现左旋支动脉远端狭窄以及左心室后下壁动脉瘤形成。超声心动图强烈提示左心室假性动脉瘤。手术中，一个巨大的后下壁动脉瘤与心包紧密粘连。建立体外循环后，夹闭主动脉并灌注冷心脏停搏液，未切除动脉瘤而是将其打开。左心室后下壁有一个4厘米×5厘米的缺损，与动脉瘤腔相通。用补片封闭缺损。通过组织学检查确诊为左心室假性动脉瘤。术后过程顺利，患者于术后第29天出院。
