Impact of effective regurgitant orifice area on outcome of secondary mitral regurgitation transcatheter repair. [PDF]

Clin Res Cardiol, 2021
Abstract Objectives To assess the value of effective regurgitant orifice (ERO) in predicting outcome after edge-to-edge transcatheter mitral valve repair (TMVR) for secondary mitral regurgitation (SMR) and identify the optimal cut-off for patients’ selection.

Load dependence of the effective regurgitant orifice area in a sheep model of aortic regurgitation.

Journal of the American College of Cardiology, 1991
Treatment of patients with aortic regurgitation with vasodilators reduces regurgitant volume, ventricular dilation and left ventricular mass. Although these effects are presumably due to afterload reduction, it is also possible that the aortic regurgitant orifice area is not constant.

Effective regurgitant orifice area: a noninvasive Doppler development of an old hemodynamic concept.

Journal of the American College of Cardiology, 1994
The purpose of this study was to determine the feasibility, relation to other methods and significance of the effective regurgitant orifice area measurement.Assessment of the severity of valvular regurgitation (effective regurgitant orifice area) has not been implemented in clinical practice but can be made by Doppler echocardiography.Effective ...

Real-Time 3-Dimensional Echocardiographic Assessment of Effective Regurgitant Orifice Area in Dogs With Myxomatous Mitral Valve Disease. [PDF]

J Vet Intern Med, 2017
Background: Effective regurgitant orifice area (EROA), calculated from the vena contracta width (VCW) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation.

Application of the proximal flow convergence method to calculate the effective regurgitant orifice area in aortic regurgitation.

Journal of the American College of Cardiology, 1998
We sought to determine the reliability of the proximal isovelocity surface area (PISA) method for calculation of effective regurgitant orifice (ERO) of aortic regurgitation (AR).The ERO area can be calculated by the PISA method, but this method has not been validated in AR.ERO calculation by the PISA method was undertaken prospectively in 71 ...

Effect of load alterations on the effective regurgitant orifice area in chronic aortic regurgitation [PDF]

Heart, 2002
Objective: To evaluate the load dependence of effective regurgitant orifice area (ROA) in an animal model of chronic aortic regurgitation. Methods: Eight sheep were studied 10–20 weeks after the surgical creation of aortic regurgitation.

Determinants of regurgitant volume in mitral regurgitation: contrasting effect of similar effective regurgitant orifice area in functional and organic mitral regurgitation [PDF]

European Heart Journal - Cardiovascular Imaging, 2011
Quantitative assessment of the severity of mitral regurgitation (MR) is based on the calculation of the effective regurgitant orifice (ERO), a measure of lesion severity, and of the regurgitant volume (RVol), a measure of left ventricular volume overload.

Influence of aortic pressure on effective regurgitant orifice area in aortic regurgitation. [PDF]

Circulation, 1992
BACKGROUND The regurgitant volume in aortic regurgitation is determined by the diastolic filling period, the pressure gradient between the left ventricle and aorta, and the hemodynamic size of the regurgitant orifice area. METHODS AND RESULTS To test the hypothesis that the aortic ...

An alternative isovelocity surface model for quantitation of effective regurgitant orifice area in mitral regurgitation with an elongated orifice application to functional mitral regurgitation.

JACC. Cardiovascular imaging, 2011
The purpose of this study was to develop and test a simple, clinically practical alternative isovelocity surface (ISVS) model for calculating effective regurgitant orifice area (EROA) in mitral regurgitation (MR) when the regurgitant orifice is elongated, such as in functional MR.Clinical experience and 3-dimensional imaging suggest that the ...

Beyond effective regurgitant orifice in quantitative assessment of tricuspid regurgitation: impact on clinical outcomes [PDF]

European Heart Journal, 2020
Abstract Background Quantification in tricuspid regurgitation has been poorly investigated. Recommended methods and thresholds are directly translated from mitral regurgitation; however, the anatomy, hemodynamics, and regurgitant orifice geometry are different in TR. Effective regurgitant orifice (ERO)
