实时三维超声心动图评价肺动脉瓣狭窄的临床研究

摘要

Objective: To evaluate the effect of real-time three-dimensional echocardiography ( RT-3DE ) in patients with pulmonary valvular stenosis ( PVS ) .Methods: Totally 86 patients with PVS diagnosed by two dimensional echocardiography were examined with RT-3DE.Results:Pulmonary leaflet numbers in 67.44%(58/86 ) patients with PVS were determined .The results of RT-3 DE had better correlation with the the surgical results than two dimensional echocardiography ( P<0 .05 ) .The r between the aera of PV with the correction of the body surface area and the speed of the PV was 0 .76 .The stenosis flow of PVS was showed three-dimensionally by real-time three-dimensional color Doppler flow imaging ( RT-3D color).Conclusion: RT-3DE can supply more information in diagnosing PVS .%目的：探讨实时三维经胸超声心动图（RT-3DE）对评价肺动脉瓣狭窄（PVS）的价值。方法：二维经胸超声心动图诊断为PVS的86例患者，同时接受RT-3DE检查。结果：RT-3DE可确定PV瓣叶数目者占67．44％（58/86），PVS二维测值、三维测得面积分别与手术结果相比，后者相关系数更高（P＜0．05）。经过体表面积矫正后的PVS三维面积与肺动脉瓣血流速度的相关系数r＝0．76。实时三维血流可清晰显示PVS立体狭窄血流。结论：RT-3 DE可以为诊断PVS提供更丰富的信息。
