多平面经食管超声心动图的临床应用

Clinical application of multiplane transesophageal echocardiography

对164例心血管病患者进行多平面经食管超声心动图（MTEE）的研究，依次于胃底、胃食管交界处、食管下段、食管中段、食管中上段及食管上段6个水平，旋转探头品片0°～180°，全面观察心脏的形态结构，并将MTEE与经胸壁超声心动图（TTE）进行比较，其诊断完全符合率为55．49％，43．29％的患者MTEE补充了TTE的诊断，1．22％的患者完全纠正了TTE的诊断。31例术中行MTEE检查者，MTEE与手术结果完全符合率为90．32％，部分符合率为9．68％，而TTE与手术结果完全符合率为58．06％，部分符合率为41．94％。认为，MTEE的临床应用十分广泛，在探查二尖瓣病变、主动脉瓣病变、房间隔缺损、Valsalva窦瘤破裂及主动脉夹层等病变具有其独特的优越性。

164 patients were studied by inultiplbe tybesophageal echocardiography (MTEE). The cardiac structures were visualed by rotating phased array 1°~180° on the probe tip at six different gastric and esophegeal levels. The results of MTEE were compared with those of TTE. The diagnoses made by TTE were partially corrected by MTEE in 71 (43. 29%) cases and completely corrected by MTEE in 2(1. 22% ) cases.In 31 cases the daignoses tnade by multiplane intraoperative transesophageal echocardiography were proven 96.32% completely accurate when compared with the diagnoses of operation,while only 58. 06% by TTE. The results demonstrated that MTEE was very. accurate and useful in detection of cadiovascular diseases.
