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.

Comparison and Agreement of Echocardiographic Volumetric Methods for Quantifying Mitral Regurgitation in Dogs with Myxomatous Mitral Valve Disease [PDF]

Animals
Quantitative assessment of mitral regurgitation (MR) in dogs with myxomatous mitral valve disease (MMVD) is influenced by the method used to estimate left ventricular volume.

Quantification of mitral regurgitation: from traditional methods to artificial intelligence [PDF]

Cardiovascular Ultrasound
Mitral regurgitation (MR) is a common valvular disorder and associated with adverse outcomes. Echocardiography is the primary imaging modality for MR assessment; however, standard methods rely on geometric assumptions and single-frame analysis, which are

Left atrial filling volume can be used to reliably estimate the regurgitant volume in mitral regurgitation

Journal of the American College of Cardiology, 1999
The objective was to analyze the accuracy and diagnostic value of the estimated regurgitant volume of mitral regurgitation using 1) left atrial volume variation during ventricular systole (left atrial filling volume) and 2) the percent of systolic pulmonary vein velocity integral compared with its total.Left atrial filling volume (LAfill), which ...

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

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.

Mitral Transcatheter Edge-to-Edge Repair in Patients With Advanced Heart Failure: A Single-Center Experience and Insights Into Anatomical and Clinical Determinants of Procedural Complexity. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background Advanced heart failure (HF) remains a clinical challenge, and mitral transcatheter edge‐to‐edge repair (M‐TEER) has emerged as a potential bridging strategy. Aims To describe the clinical outcomes of M‐TEER in a single‐center cohort of patients with advanced HF and to identify anatomical and clinical features potentially associated ...

Minimally Invasive, Echocardiography‐Guided Mouse Model of Degenerative Mitral Regurgitation Recapitulates Cardiac Remodeling and Arrhythmogenesis [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Degenerative mitral regurgitation (MR) is a progressive valvular disorder that causes atrial enlargement, cardiac remodeling, heart failure, and arrhythmias.

Sex difference in mitral valve prolapse regurgitant volume is resolved by normalization of regurgitant volume to left ventricular end-diastolic volume

International Journal of Cardiovascular Imaging
AbstractWomen with primary mitral insufficiency have a smaller regurgitant volume at the same regurgitant fraction than men. We hypothesized that normalizing regurgitant volume with left ventricular end-diastolic volume or allometric scaling would eliminate the difference in regurgitant volume between women and men.

Left atrial strain in mitral valve disease: a comparative analysis of regurgitation and stenosis [PDF]

BMC Cardiovascular Disorders
Background Left atrial (LA) strain analysis is an emerging echocardiographic technique for assessing LA function. This study aimed to compare LA strain parameters in patients with mitral stenosis (MS) and mitral regurgitation (MR) to identify ...

Intraoperative Transesophageal Echocardiography Quantification of Mitral Regurgitation by Regurgitation Volume and Fraction Using 2D and 3D Techniques

Annals of Cardiac Anaesthesia
Background and Aims: Intraoperative quantification of mitral regurgitation (MR) is sometimes necessary to quantify the severity of incidentally detected MR during cardiac surgeries.
