摘要

在患者一生中确定的二尖瓣动脉瘤病例尚未在文献中描述。使用机械扇形扫描仪,我们能够诊断二尖瓣动脉瘤在22岁的男子患有风湿性主动脉狭窄不全。实时,横断面图像显示一个动脉瘤,其局限于前二尖瓣小叶近端。在舒张期,血液从不足的主动脉回流,确定动脉瘤向左心房腔扩张。在左流出道的m型回声中也发现了从主动脉瓣表面突出的细菌植被。患者死于感染性心内膜炎引起的不可逆性心功能不全,经尸检确认超声心动图诊断。

Echocardiographic diagnosis of mitral valve aneurysm.

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.
