Left ventricular (LV) pseudoaneurysm is a serious complication of periannular extension of infective endocarditis (IE). Because pseudoaneurysm carries a high risk of rupture, its detection and evaluation are crucial for patient management and surgical planning. We report 2 cases with LV pseudoaneurysms, one near the aortic valve and the other near the mitral valve, which were caused by IE and treated successfully. In both cases, cardiac multidetector-row computed tomography enabled detection of the LV pseudoaneurysm and a detailed demonstration of its anatomic relationship with surrounding structures, which helped guide surgical planning.
左心室假性动脉瘤是感染性心内膜炎（IE）累及心周区域的严重并发症。由于假性动脉瘤有很高的破裂风险，因此对其进行检测和评估对于患者的管理和手术计划至关重要。我们报告了 2 例由 IE 引起的位于主动脉瓣附近和二尖瓣附近的左心室假性动脉瘤病例，均成功得到治疗。在这 2 个病例中，心脏多排螺旋 CT 能够检测到左心室假性动脉瘤，并详细显示其与周围结构的解剖关系，这有助于指导手术计划。
