Left ventricular pseudoaneurysm is a rare condition because in most instances ventricular free-wall rupture leads to fatal pericardial tamponade. Rupture of the free wall of the left ventricle is a cata-strophic complication of myocardial infarction, occurring in approximately 4% of pa-tients with infarcts, resulting in immediate collapse of the patient and electromechanical dissociation. In rare cases the rupture is contained by pericardial and fibrous tissue, and the result is a pseudoaneurysm. The left ventricular pseudoaneurysm contains only pericardial and fibrous elements in its wall-no myocardial tissue. Because such aneurysms have a strong tendency to rupture, this disorder may lead to death if it is left surgically untreated.
In this case report, we present a patient who underwent successful repair of a left ventricular pseudoaneurysm, which followed a myocardial infarction that was caused by occlusion of the left circumflex coronary artery. Although repair of left ventricular pseudoaneurysm is still a surgical challenge, it can be performed with acceptable results in most patients.
左心室假性动脉瘤是一种罕见病症，因为在大多数情况下，心室游离壁破裂会导致致命的心包填塞。左心室游离壁破裂是心肌梗死的一种灾难性并发症，约4%的梗死患者会出现这种情况，会导致患者立即昏迷和电机械分离。在罕见情况下，破裂会被心包和纤维组织包裹，结果形成假性动脉瘤。左心室假性动脉瘤的壁仅包含心包和纤维成分，没有心肌组织。由于此类动脉瘤极易破裂，如果不进行手术治疗，这种病症可能会导致死亡。
在本病例报告中，我们介绍了一名成功修复左心室假性动脉瘤的患者，该假性动脉瘤继发于左旋支冠状动脉闭塞所致的心肌梗死。尽管左心室假性动脉瘤的修复仍是一项外科挑战，但在大多数患者中进行该手术可取得可接受的效果。
