51±13(25～72)岁的49(男8、女41)例二尖瓣狭窄(MS)患者均经Doppler(心尖声窗)和两维(2D)超声心动图检查,分别测定二尖瓣瓣口面积(MVOA).试析Doppler(压力减半法)测定MVOA的准确性,特别是心房颤动和并存的二尖瓣反流(MR)对测值准确性的影响.20例、4例患者分别在超声检查后7天内和3个月内接受心导管检查,其中18例按修正的Gorlin公式(取常数40)计算有效MVOA,另6例定性判断MS程度.全组MVOA测值,Doppler法同2D法相关良好(1.4±0.6对1.4±0.60cm~2,r=0.90,SEE=
49 (male 8, female 41) cases of mitral stenosis (MS) in 51 ± 13 (25-72) years of age were examined by Doppler and 2D echocardiography. (MVOA) .Analysis of Doppler (pressure halved method) to determine the accuracy of MVOA, in particular, atrial fibrillation and coexisting mitral regurgitation (MR) on the measurement accuracy.Of 20 cases, 4 The patients underwent cardiac catheterization within 7 days and within 3 months after ultrasound examination, respectively, of which 18 were evaluated according to the modified Gorlin formula (taking a constant of 40), and 6 were used to determine the degree of MS qualitatively.The MVOA score, The Doppler method is well correlated with the 2D method (1.4 ± 0.6 vs 1.4 ± 0.60 cm ~ 2, r = 0.90, SEE =
