1020-7 Afterload Dependence of Mitral Regurgitant Volume and Regurgitant Orifice Area by Quantitative Doppler

Journal of the American College of Cardiology, 1995
Quantitation of the severity of mitral regurgitation (MR) is complicated by changes in loading conditions that occur either spontaneously or as a result of therapy. Effective regurgitant orifice area has been proposed as a more fundamental measure of the severity of MR than regurgitant volume.

The average pixel intensity method and outcome of mitral regurgitation in mitral valve prolapse

, 2020
Background: Mitral regurgitation (MR) is a frequent consequence of mitral valve prolapse (MVP). However, the echocardiographic grading of MR is challenging, and the recommended grading parameters have several limitations.

Genesis of the austin flint murmur: Relation to mitral inflow aortic regurgitant flow dynamics

, 1993
Objectives. This study was designed to elucidate the genesis of the Austin Flint murmur.Background. The Austin Flint murmur is an apical diastolic rumble associated with significant aortic regurgitation.

Right ventricular reserve post mitral valve repair is associated with heart failure hospitalization

Pulmonary Circulation, 2020
Right ventricular impairment is a predictor of cardiovascular outcomes in patients with degenerative mitral regurgitation. However, the time course of right ventricular functional changes post-surgical mitral valve repair remains largely unknown. Herein,

Quantification of Mitral Regurgitation in Anatolian Shepherd Dogs with Asymptomatic Degenerative Mitral Valve Disease [PDF]

Pakistan Veterinary Journal, 2016
Degenerative mitral valvular disease (DMVD) is the most frequent cardiac disease, causing mitral regurgitation (MR) in dogs. The purpose of this study was to compare the ratio of the regurgitant jet area (RJA) to the left atrial area (LAA) (RJA/LAA) with

IMPACT OF THE ETIOLOGY OF MITRAL REGURGITATION ON CALCULATION OF REGURGITANT VOLUME USING THE PROXIMAL FLOW CONVERGENCE METHOD

Journal of the American College of Cardiology, 2013
To evaluate the impact of mitral regurgitation (MR) etiology on the accuracy of the proximal isovelocity surface area (PISA) method, we compared PISA method with conventional volumetric method in 176 patients with degenerative MR (prolapse or flail, group A) and 126 with functional MR (group B).

Rest and stress echocardiographic predictors of prognosis in patients with left ventricular dysfunction and functional mitral regurgitation

, 2008
We evaluate, in 37 consecutive patients (mean age 67 +/- 9 years) with functional mitral regurgitation (FMR), several rest and stress echocardiographic predictors of outcome.

Intraoperative Quantification of Severe Mitral Regurgitation: A Comparative Assessment of Two-Dimensional Flow Convergence, Three-Dimensional Volumetric, and Doppler-Based Methods

Journal of Cardiovascular Development and Disease
Accurate quantification of mitral regurgitation (MR) is central to perioperative decision-making, yet the agreement and interchangeability of commonly used echocardiographic methods remain uncertain.
