    Rheumatoid valve disease is a general health problem of developing countries, and it mainly affects after the age of 40. Assessment of the correct mitral valve area (MVA) is important for the treatment of rheumatoid valve disease. However, there are contradictions between the three-dimensional (3D) and two-dimensional (2D) methods. A measurement with 3D echocardiography is a more accurate method to measure the MVA. However, in centers without 3D echocardiography, there are some difficulties in the accurate measurement of the MVA. The aim of this study was to assess the value of 2D transesophageal echocardiography (TEE) mitral valve vena contracta area (VCA) in predicting the severity of rheumatoid mitral stenosis (RMS) by comparing 3D planimetry. A total of 24 patients (10 females and 14 males) who were diagnosed with mild/moderate/severe RMS with using pressure half time, mean transmitral gradient, and planimetry methods were included in this study. 3D images were acquired using the 3D zoom and full volume. 2D TEE VCA was measured at an angle of 140° and 60°, which was perpendicular to the former, with color Doppler and the VCA was measured with an ellipsoid area using mathematical formula. There was statistically significant relationship between the measurements of 2D VCA and 3D zoom mode MVA planimetry and MVA full measurements (MVA full volume) (p < 0.01). Calculation of the valvular area after measuring the mitral valve VCA with 2D TEE is a reliable method that is usable in centers without 3D echocardiography.

    Quantification of rheumatic mitral stenosis severity with three-dimensional vena contracta area
    (Wiley, 2019) Gök, Gülay; Çınar, Tufan; Sayar, Nurten
    Introduction: Rheumatic mitral stenosis (MS) is an important health issue in developing countries. Assessment of the correct mitral valve area (MVA) is essential for the timing of intervention. Most of the parameters for the assessment of rheumatic MS are derived from Two-dimensional (2D) echocardiography. Three-dimensional (3D) echocardiography is commonly used in our daily practice at the present time. The aim of this study was to assess the value of 3D echocardiography mitral valve vena contracta area (VCA) in predicting the severity of Rheumatic MS by comparing 3D planimetry. Methods: The patients, who had been diagnosed as mild, moderate, and severe rheumatic MS with conventional methods (pressure half time, planimetry) by 2D transesophageal echocardiography (TEE)/ transthoracic echocardiography (TTE), underwent 3D TEE evaluation. Also, the patients who had an atrial fibrillation and more than moderate aortic regurgitation were included in the study. 3D TEE full volume mitral valve VCA was measured in end-diastole during its largest dimensions. 3D TEE full volume and 3D zoom MVA planimetry were measured at the end-diastole during the mitral valve's largest opening. Results: We studied 40 patients (the mean age: 51.1 +/- 11.6 years, 31 females) with rheumatic MS. 3D TEE VCA was found to be highly correlated with the 3D TEE MVA (r = 0.82, P < 0.001). Conclusion: Our study findings provide evidence that 3D TEE mitral valve VCA can be additionally used in detecting the severity of rheumatic MS.
