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.

Ross-kabbani operation in an infant with mitral valve dysplasia. [PDF]
, 2009 Background. Mitral valve replacement can be very difficult to obtain in infants because the valve annulus diameter can be smaller than the available prosthesis. Case Report.

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

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 ...

Parameters of the mitral apparatus in patients with ischemic and nonischemic dilated cardiomyopathy [PDF]
, 2023 Publisher Copyright: © The Author(s) 2023.The mitral valve apparatus is a complex structure consisting of several coordinating components: the annulus, two leaflets, the chordae tendineae, and the papillary muscles. Due to the intricate interplay between

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 ...

Primary cilia defects causing mitral valve prolapse
Science Translational Medicine, 2019 Genetic variations in primary cilia genes cause defects during valve morphogenesis that can progress to mitral valve prolapse in the adult. DZIPping along to diagnosis Mitral valve prolapse is a common congenital abnormality that can cause severe ...

Contractile properties of the right atrial myofilaments in patients with myxomatous mitral valve degeneration [PDF]
, 2014 BACKGROUND: Myxomatous degeneration of the mitral valve is a common pathological finding in mitral valve surgery and the most common reason for severe mitral valve regurgitation.

Mechanical or Biologic Prostheses for Aortic‐Valve and Mitral‐Valve Replacement
New England Journal of Medicine, 2017 BACKGROUND In patients undergoing aortic‐valve or mitral‐valve replacement, either a mechanical or biologic prosthesis is used. Biologic prostheses have been increasingly favored despite limited evidence supporting this practice. METHODS We compared long‐

A Computational Framework for Atrioventricular Valve Modeling using Open-Source Software [PDF]
arXiv, 2022 Atrioventricular valve regurgitation is a significant cause of morbidity and mortality in patients with acquired and congenital cardiac valve disease. Image-derived computational modeling of atrioventricular valves has advanced substantially over the last decade and holds particular promise to inform valve repair in small and heterogeneous populations ...
