Left ventricular pseudoaneurysm is a rare complication of myocardial infarction or cardiac trauma. We report a case of sudden death from rupture of such a lesion. Clinically, these lesions need to be distinguished from the other ventricular out-pouching lesions (true aneurysms and diverticula) because of their greater likelihood for rupture. Pathologically, apart from often being infarct-related, they are characterized by a narrow connection with the ventricular cavity and a fibrous outer wall that is devoid of myocardial tissue.
左心室假性动脉瘤是心肌梗死或心脏创伤的一种罕见并发症。我们报告一例因这种病变破裂导致猝死的病例。临床上，由于这些病变破裂的可能性更大，需要将它们与其他心室膨出病变（真性动脉瘤和憩室）区分开来。病理上，除了常与梗死相关外，其特征是与心室腔的连接狭窄，外壁为纤维性，无心肌组织。
