Two cases of left ventricular pseudoaneurysm formation developing post-operatively after mitral valve replacement are reported. The chest radiographs showed an abnormal protuberance on the left heart border at the site of the "third mogul". The definitive diagnosis of this protuberance, resulting from the development of a left ventricular aneurysm, was made on angiography in each case. This site is unusual for left ventricular aneurysm formation, with the exception of the annular subvalvular aneurysm described in the negro population. Relevant aetiological factors in the development of these post-operative left ventricular pseudoaneurysms are considered. Since pseudoaneurysms are more prone to rupture than true aneurysms, it is concluded that early diagnosis of development of these left ventricular pseudoaneurysms should be made.
本文报道了两例二尖瓣置换术后发生左心室假性动脉瘤的病例。胸部X线片显示在“第三隆凸”部位的左心缘有异常突出。通过血管造影对每例患者由左心室动脉瘤形成导致的这种突出进行了明确诊断。除了黑人人群中描述的瓣环下动脉瘤外，该部位发生左心室动脉瘤并不常见。文中考虑了这些术后左心室假性动脉瘤形成的相关病因。由于假性动脉瘤比真性动脉瘤更容易破裂，得出结论：应尽早诊断这些左心室假性动脉瘤的形成。
