目的探讨经食管超声心动图在诊断二尖瓣-主动脉瓣间纤维假性动脉瘤的应用价值。方法回顾分析5例二尖瓣-主动脉瓣间纤维假性动脉瘤术前超声心动图资料及随访结果,对比经胸及经食管超声心动图成像效果,总结其声像图特点。结果经食管超声较经胸二维超声能更加准确的分辨二尖瓣-主动脉瓣间纤维假性动脉瘤及伴发心脏病变的位置、形态,经食管实时三维超声能获得比二维超声更加丰富的形态学信息。结论经食管超声心动图较经胸超声心动图在二尖瓣-主动脉瓣间纤维假性动脉瘤的诊断与鉴别方面,具有更重要的应用价值。
Objective To investigate the value of transesophageal echocardiography in the diagnosis of mitral-aortic valve pseudo-aneurysm. Methods The echocardiographic data and follow-up results of 5 cases of mitral-aortic valve pseudo-aneurysm were retrospectively analyzed. The transthoracic and transesophageal echocardiographic imaging results were compared and their sonographic features were summarized. Results Compared with transthoracic two-dimensional ultrasonography, transesophageal echocardiography could identify more accurately the position and morphology of mitral-aortic valve pseudo-aneurysm and heart disease, Rich morphological information. Conclusion Transesophageal echocardiography is more important than transthoracic echocardiography in the diagnosis and differential diagnosis of mitral-aortic fibular pseudoaneurysm.
