Modeling the Mitral Valve [PDF]
arXiv, 2022 This thesis is concerned with modeling and simulation of the mitral valve, one of the four valves in the human heart. The valve is composed of leaflets attached to a ring, the free edges of which are supported by a system of chordae, which themselves are anchored to muscles inside the heart.

Echocardiography of the mitral valve
Journal of the Saudi Heart Association, 2010 Mitral valve disease is the second most common valvular heart disease after the aortic valve worldwide. Mitral valve has historically been a structure of interest by pioneers in echocardiography. One of the earliest applications of echocardiography was in the diagnosis of valvular heart disease, particularly mitral stenosis.

The potential of mitral valve quantification in cardiovascular surgery
Alʹmanah Kliničeskoj Mediciny, 2018 Objective: To identify specifics of mitral valve anatomy in patients with mitral insufficiency of various origin using the Mitral Valve Quantification (MVQ) technique for an optimal choice of mitral valve repair strategy. Materials and methods: The study

CNN-based fully automatic mitral valve extraction using CT images and existence probability maps [PDF]
arXiv, 2023 Accurate extraction of mitral valve shape from clinical tomographic images acquired in patients has proven useful for planning surgical and interventional mitral valve treatments. However, manual extraction of the mitral valve shape is laborious, and the existing automatic extraction methods have not been sufficiently accurate.

Isolated non-obstructive accessory mitral valve tissue in an adult mimicking ruptured chordae
Indian Heart Journal, 2013 Accessory mitral valve tissue is commonly associated with other congenital heart diseases and is usually detected in children causing left ventricular outflow tract obstruction.

Interactive-Automatic Segmentation and Modelling of the Mitral Valve [PDF]
, 2019 Mitral valve regurgitation is the most common valvular disease, affecting 10% of the population over 75 years old. Left untreated, patients with mitral valve regurgitation can suffer declining cardiac health until cardiac failure and death. Mitral valve repair is generally preferred over valve replacement. However, there is a direct correlation between

Computational fluid dynamics modelling of left valvular heart diseases during atrial fibrillation [PDF]
PeerJ, 4: e2240, 2016, 2016 Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics.

Heatmap-based 2D Landmark Detection with a Varying Number of Landmarks [PDF]
arXiv, 2021 Mitral valve repair is a surgery to restore the function of the mitral valve. To achieve this, a prosthetic ring is sewed onto the mitral annulus. Analyzing the sutures, which are punctured through the annulus for ring implantation, can be useful in surgical skill assessment, for quantitative surgery and for positioning a virtual prosthetic ring model ...

Mitral Valve Prolapse, Ventricular Arrhythmias, and Sudden Death.
Circulation, 2019 Despite a 2% to 3% prevalence of echocardiographically defined mitral valve prolapse (MVP) in the general population, the actual burden, risk stratification, and treatment of the so-called arrhythmic MVP are unknown. The clinical profile is characterized

European Heart Journal, 2018 Aims We sought to evaluate the outcomes of transcatheter mitral valve replacement (TMVR) for patients with degenerated bioprostheses [valve-in-valve (ViV)], failed annuloplasty rings [valve-in-ring (ViR)], and severe mitral annular calcification [valve ...
