摘要
目的探讨超声心动图测量二尖瓣狭窄瓣口面积(MVA)的准确性。方法 50例行二尖瓣置换术的风湿性二尖瓣狭窄患者,术前采用二维超声心动图法(2DE法)、多普勒压力降半时间法(PHT法)及实时三维超声心动图法(RT3DE法)测量MVA(即MVA2DE、MVAPHT及MVART3DE),与术后描记法(OP法)测量的MVA(MVAOP)进行比较分析。结果与MVAOP比较,MVART3DE、MVA2DE及MVAPHT差异无统计学意义(P>0.05)。与MVAOP相比,MVART3DE(r=0.87),MVAPHT(r=0.76)及MVA2DE(r=0.75)的相关系数逐渐递减。结论超声心动图定量评价二尖瓣狭窄程度简便、准确、可行,但RT3DE更能准确反映二尖瓣膜狭窄的真实程度。
Objective To explore the accuracy of echocardiography in assessing stenotic mitral valve orifice area（MVA）.Methods Fifty patients with rheumatic mitral valve stenosis underwent mitral valve replacement surgery.MVA was recorded by two-dimensional echocardiography（MVA2DE）,Doppler pressure half-time method（MVAPHT） and real-time three-dimensional echocardiography（MVART3DE）.The postoperative determination of MVA（MVAOP） was used as the gold standard for comparison.Results The correlation coefficients of MVART3DE,MVAPHT,MVA2DE and MVAOP were 0.87,0.76 and 0.75,respectively.No statistical differences were found between MVART3DE,MVA2DE,MVAPHT and MVAOP（P0.05）.Conclusion The echocardiography,especially RT3DE,can provide a simple,accurate and reliable approach for the quantification of mitral stenosis.
