Doming Volume in Mitral Valve Prolapse: Pathophysiology, Imaging Implications and Clinical Relevance [PDF]

Journal of Cardiovascular Development and Disease
Mitral valve prolapse represents the most common cause of primary mitral regurgitation in Western countries and has traditionally been viewed as a disorder driven by valvular incompetence and chronic volume overload.

Resolution of severe secondary mitral valve regurgitation following aortic valve replacement in infective endocarditis [PDF]

SAGE Open Medical Case Reports, 2021
We present the case of a patient with infective endocarditis anesthetized for replacement of severely regurgitant aortic valve. Intraoperative transesophageal echocardiography revealed a new diagnosis of severe secondary mitral regurgitation.

Spontaneous Reduction in Mitral Valve Regurgitation in Three Dogs With Severe Myxomatous Mitral Valve Disease: An Unusual Case Report. [PDF]

Vet Med Sci
In dogs with MMVD, severe valvular degeneration with chordae tendineae rupture is generally associated with a poor prognosis despite medical management. These three cases demonstrate spontaneous reduction in mitral regurgitation accompanied by decreased coaptation gap, reduced regurgitant volume, reverse cardiac remodelling, discontinuation of ...

Left Atrial Overload Can Be Used to Estimate Mitral Regurgitant Volume [PDF]

Congestive Heart Failure, 2001
This study was conducted to assess the accuracy of the estimated mitral regurgitant volume using both the left atrial filling volume and the systolic component of pulmonary vein flow expressed as the percent of its total. Since mitral regurgitation fills the left atrial chamber, the variation in atrial volume during ventricular systole has been ...

Three-Dimensional Transesophageal Echocardiographic Vena Contracta Area for Grading Mitral Regurgitation: Severity Cut-offs From a Prospective Tunisian Cohort. [PDF]

Echocardiography
Three‐dimensional vena contracta area (VCA) measured by transoesophageal echocardiography enables precise accurate quantification of mitral regurgitation severity. In a Tunisian cohort, 3D VCA showed strong correlations with conventional 2D indices and excellent diagnostic performance for severe MR, supporting its use particularly in rheumatic mitral ...

Quantitative mitral regurgitation and conventional echocardiographic variables in canine myxomatous mitral valve disease [PDF]

Frontiers in Veterinary Science
IntroductionDisease severity in dogs with myxomatous mitral valve disease (MMVD) is commonly assessed using conventional echocardiographic variables and staging systems based on cardiac remodeling and heart failure status. Multiparametric scoring systems

Comparison of circular and elliptical geometric models with optimal two-dimensional imaging view for Doppler quantification of mitral regurgitant volume in older patients [PDF]

Frontiers in Cardiovascular Medicine
BackgroundDoppler volumetric quantification of mitral regurgitation (MR) depends on accurate stroke-volume estimation, but simplified assumptions regarding mitral annular area may introduce view-dependent error, particularly in older patients. This study

Short-term effects of pimobendan in dogs with preclinical myxomatous mitral valve disease [PDF]

Frontiers in Veterinary Science
IntroductionPimobendan has been shown to delay the onset of congestive heart failure and prolong survival in dogs affected by myxomatous mitral valve disease (MMVD).

Impact of left ventricular reshaping on postinfarction functional mitral regurgitation in a chronic swine model of advanced heart failure [PDF]

JTCVS Open
Objective: The study objective was to evaluate the efficacy and feasibility of left ventricular reshaping in a swine model of late-stage ischemic heart failure with marked left ventricular dilation and functional mitral regurgitation.

Association between the proportionality of functional mitral regurgitation and survival after mitral valve operationCentral MessagePerspective

JTCVS Open
Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden.
