Cases of mitral valve aneurysm determined during the patient's lifetime have not yet been described in literature. Using a mechanical sector scanner we were able to diagnose a mitral valve aneurysm in a 22-yr-old man suffering from rheumatic aortic steno-insufficiency. The real-time, cross-sectional image showed an aneurysm which was limited to the proximal part of the anterior mitral leaflet. During diastole the reflow of blood from the insufficient aorta determined an enlargement of the aneurysm towards the left atrial cavity. Bacterial vegetation which protruded from the aortic valvular surface and which was responsible for abnormal echoes in the M-mode in the left outflow tract was also detected. The patient died of irreversible cardiac insufficiency caused by the infectious endocarditis, and upon autopsy the echocardiographic diagnosis was confirmed.
二尖瓣动脉瘤在患者生前确诊的病例在文献中尚未见报道。我们使用机械扇形扫描仪，在一名患有风湿性主动脉瓣狭窄合并关闭不全的22岁男性患者中诊断出二尖瓣动脉瘤。实时横断面图像显示动脉瘤局限于二尖瓣前叶近端。舒张期，主动脉瓣反流使动脉瘤向左心房腔扩大。还检测到从主动脉瓣膜表面突出的细菌性赘生物，其导致左心室流出道M型超声出现异常回声。患者死于感染性心内膜炎引起的不可逆性心脏功能不全，尸检证实了超声心动图诊断。
