An Appraisal of the Association of Clinical Outcomes With the Severity of Regurgitant Volume Relative to End-Diastolic Volume in Patients With Secondary Mitral Regurgitation

JAMA Cardiology, 2020
Two randomized clinical trials of transcatheter edge-to-edge mitral valve repair in patients with secondary mitral regurgitation (the Multicentre Randomized Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients With Severe Secondary Mitral Regurgitation [MITRA-FR] and the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous

Prognostic impact of regurgitant volume to left atrial volume ratio on ventricular functional mitral regurgitation

European Heart Journal - Cardiovascular Imaging
Abstract Aims In patients with ventricular functional mitral regurgitation (VFMR) undergoing transcatheter edge-to-edge repair (M-TEER), the prognostic significance of the ratio between mitral regurgitant volume and left atrial volume (LAV) remains unclear.

Prognostic Value of Left Atrial Volume in Asymptomatic Organic Mitral Regurgitation

Journal of the American Society of Echocardiography, 2013
Basal left atrial volume (LAV) indexed to body surface area (LAVI) predicts adverse events in patients with organic mitral regurgitation, but information is lacking regarding change in left atrial volume during follow-up.One hundred forty-four asymptomatic patients (mean age, 71 ± 12 years; 66% women; mean ejection fraction, 66 ± 4.8%) with moderate to

Direct visualization of regurgitant orifice by CMR reveals differential asymmetry according to etiology of mitral regurgitation.

open access: yesJACC: Cardiovascular Imaging, 2011
ObjectivesThis study sought to characterize the shape of regurgitant orifice area (ROA) and mitral apparatus in various forms of mitral regurgitation (MR) by cardiac magnetic resonance (CMR).BackgroundROA is an accepted parameter of MR severity. However,

[Quantification of mitral regurgitation by Doppler color flow mapping: comparison of mitral regurgitant fraction and volume with Doppler measurements].

Journal of cardiology, 1993
Color flow imaging of the regurgitant areas has been used to quantitate the severity of valvular regurgitation, however, the exact relationship between color flow areas and regurgitant volumes or fraction has not been clarified. This study was designed to determine whether measurements of jet flow areas and distances using color flow imaging are ...

Left atrial volume overload in mitral regurgitation: A two dimensional echocardiographic study

The American Journal of Cardiology, 1982
Left atrial volume in patients with mitral valve disease was studied with two dimensional echocardiography. The left atrial dimension was derived by planimetry of the left atrial area and, assuming spherical geometry, left atrial volume was calculated. Patients with severe mitral regurgitation had marked systolic expansion of the left atrium with large

Left atrial function in acute mitral regurgitation. Factors which modify the regurgitant volume.

Herz, 1981
Dynamic geometry of the left atrium was studied in open-chest dogs instrumented with ultrasonic dimension gauges for the measurement of the transverse diameter together with left ventricular dimensions and left atrial and ventricular pressures. Three definite phasic changes of the left atrial diameter were observed during the cardiac cycle at the ...

Prognostic value of echocardiographic-derived stroke volume in severe primary mitral regurgitation

European Heart Journal - Cardiovascular Imaging
Abstract Aims Studies have demonstrated the importance of forward flow, and specifically of stroke volume (SV) and SV index (SVI), as prognostic markers in different cardiovascular diseases. In this study, we aim to evaluate the association between SV and SVI thresholds and prognosis in patients with ...
