Quantification of mitral regurgitation orifice area by 3-dimensional echocardiography: comparison with effective regurgitant orifice area by PISA method and proximal regurgitant jet diameter

International Journal of Cardiology, 2002
The evaluation of mitral regurgitation (MR) by 3-dimensional (3D) echo has generally been performed by reconstruction of Doppler regurgitant jets but there are little data on measuring anatomic regurgitant orifice area (AROA) directly from 3D mitral valve (MV) reconstructions.Transoesophageal echo (TOE) 3D images were acquired from 38 unselected ...

Mitral regurgitation and dyspnoea: the expanding role of mitral effective regurgitant orifice among un-selected patients

Journal of Cardiovascular Medicine, 2020
Aims Mitral regurgitation is frequent in the general population and among suspected heart failure patients; however, to what extent it contributes to dyspnoea is unclear. We hypothesized mitral regurgitation to have a role in determining dyspnoea in unselected ambulatory patients. Methods

Effective regurgitant orifice area in tricuspid regurgitation: Clinical implementation and follow-up study

American Heart Journal, 1994
Analysis of the flow-convergence zone proximal to a regurgitant orifice permits the noninvasive, quantitative measurement of clinically useful parameters of valvular insufficiency. However, many indexes such as flow rate reflect not only the size of the regurgitant lesion but are also highly dependent on the hemodynamic loading conditions.

Right Ventricular Function and Outcomes Stratified by the Effective Regurgitant Orifice Area in Secondary Tricuspid Regurgitation

Canadian Journal of Cardiology
In patients with moderate and severe secondary tricuspid regurgitation (STR), the effective regurgitant orifice area (EROA), corrected using the proximal isovelocity surface area (PISA) method for tricuspid valve leaflet tethering and low TR jet velocities, has an unclear threshold for identifying high-risk patients. In this study we aimed to establish

Contrasting effect of similar effective regurgitant orifice area in mitral and tricuspid regurgitation: A quantitative Doppler echocardiographic study

Journal of the American Society of Echocardiography, 2002
We compared the effect of similar effective regurgitant orifice (ERO) areas in tricuspid regurgitation (TR) and mitral regurgitation (MR) on hemodynamics and volume overload, and examined the impact on grading of TR and MR severity. In a prospective study, 95 patients with TR in sinus rhythm were compared with 95 patients with MR in sinus rhythm ...

Effective Regurgitant Orifice Area by the Color Doppler Flow Convergence Method for Evaluating the Severity of Chronic Aortic Regurgitation

Circulation, 1996
Background The aim of the present study was to evaluate dynamic changes in aortic regurgitant (AR) orifice area with the use of calibrated electromagnetic (EM) flowmeters and to validate a color Doppler flow convergence (FC) method for evaluating effective AR orifice area and regurgitant volume.
