We report a rare autopsy case of Lambl's excrescence of the aortic valve resulting in myocardial infarction. A 50-year-old female patient was referred to our hospital, but she died 4 hours after admission due to myocardial infarction. Autopsy disclosed Lambl's excrescence of the aortic valve, which obstructed the main branch of the left coronary artery. Histologically, fibrin thrombus and bacterial flora were found on surface of Lambl's excrescence. Differential diagnosis of infected Lambl's excrescence, so called endocarditis with infected vegetation, and papillary fibroelastomais discussed with a literature review.
我们报告一例罕见的尸检病例，主动脉瓣兰氏赘生物导致心肌梗死。一名50岁女性患者被转诊至我院，但入院4小时后因心肌梗死死亡。尸检发现主动脉瓣兰氏赘生物，其阻塞了左冠状动脉的主要分支。组织学检查发现兰氏赘生物表面有纤维蛋白血栓和细菌菌群。结合文献复习，对感染性兰氏赘生物（即伴有感染性赘生物的心内膜炎）与乳头肌纤维弹性组织增生症进行了鉴别诊断。
