Bioprosthetic Heart Valves: Upgrading a 50-Year Old Technology
Frontiers in Cardiovascular Medicine, 2019 Prosthetic heart valves have been commonly used to address the increasing prevalence of valvular heart disease. The ideal prosthetic heart valve substitute should closely mimic the characteristics of a normal native heart valve.

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.

Comparison of Immersed Boundary Simulations of Heart Valve Hemodynamics against In Vitro 4D Flow MRI Data [PDF]
, 2021 The immersed boundary (IB) method is a mathematical framework for fluid-structure interaction problems (FSI) that was originally developed to simulate flows around heart valves. Direct comparison of FSI simulations around heart valves against experimental data is challenging, however, due to the difficulty of performing robust and effective simulations,

Optimization of anticoagulant therapy in patients undergoing mechanical heart valve replacement
Фундаментальная и клиническая медицина, 2023 Acquired heart defects have a high prevalence among patients of different age groups and represent a significant social problem. To date, surgery remains the only effective option to treat acquired heart disease, and replacement of the dysfunctional ...

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 ...

Fatores de risco em operações valvares: análise de 412 casos
Brazilian Journal of Cardiovascular Surgery, 1997 O tratamento cirúrgico das valvopatias é muito freqüente e sua mortalidade ainda não se aproxima de zero. Neste estudo, procuramos identificar diversos fatores que poderiam aumentar o risco cirúrgico nestes procedimentos.
