Tissue Heart Valve Replacement at BSMMU- Initial Experience with Two Cases [PDF]

Bangabandhu Sheikh Mujib Medical University Journal, 2010
Research on prosthesis to replace diseased heart valves began almost simultaneously with mechanical valves which are durable but with inherent thromboembolic complication requiring life-long anticoagulant therapy and tissue valves which are more prone to

Incidence and patterns of valvular heart disease in a tertiary care high-volume cardiac center: A single center experience [PDF]

Indian Heart Journal, 2014
Background: Diseases of the heart valves constitute a major cause of cardiovascular morbidity and mortality worldwide with rheumatic heart disease (RHD) being the dominant form of valvular heart disease (VHD) in developing nations.

A coupled mitral valve -- left ventricle model with fluid-structure interaction [PDF]

arXiv, 2017
Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to explore the mechanics of valve-heart interactions using anatomically and physiologically realistic ...

Mitral valve interventions in heart failure [PDF]

ESC Heart Failure, 2018
AbstractSecondary mitral regurgitation (MR) results from left ventricular dilatation and dysfunction. Quantification of secondary MR is challenging because of the underlying myocardial disease. Clinical and echocardiographic evaluation requires a multi‐parametric approach.

Mitral valve repair in heart failure [PDF]

European Journal of Heart Failure, 2000
AbstractMitral regurgitation (MR) is a frequent complication of end‐stage heart failure. Historically, these patients were either managed medically or with mitral valve replacement, both associated with poor outcomes. Mitral valve repair via an ‘undersized’ annuloplasty repair is safe and effectively corrects MR in heart‐failure patients.

Machine Learning for Automated Mitral Regurgitation Detection from Cardiac Imaging [PDF]

In: Medical Image Computing and Computer Assisted Intervention - MICCAI 2023. pp. 236-246 (2023), 2023
Mitral regurgitation (MR) is a heart valve disease with potentially fatal consequences that can only be forestalled through timely diagnosis and treatment. Traditional diagnosis methods are expensive, labor-intensive and require clinical expertise, posing a barrier to screening for MR. To overcome this impediment, we propose a new semi-supervised model

Mitral valve opening in the ovine heart [PDF]

American Journal of Physiology-Heart and Circulatory Physiology, 1998
To study the three-dimensional size, shape, and motion of the mitral leaflets and annulus, we surgically attached radiopaque markers to sites on the mitral annulus and leaflets in seven sheep. After 8 days of recovery, the animals were sedated, and three-dimensional marker positions were measured by computer analysis of biplane videofluorograms (60/s).

Computational analysis of flow structures in turbulent ventricular blood flow associated with mitral valve intervention [PDF]

Frontiers in Physiology (2022) 752, 2021
Cardiac disease and clinical intervention may both lead to an increased risk for thrombosis events due to modified blood flow in the heart, and thereby a change in the mechanical stimuli of blood cells passing through the chambers of the heart. Specifically, the degree of platelet activation is influenced by the level and type of mechanical stresses in

A rare case series of mechanical prosthetic heart valve structural deterioration presented as severe mitral regurgitation

Heart Vessels and Transplantation, 2023
Objective: Structural valve deterioration in the form of stenosis or regurgitation or both though being a rare complication with newer generation mechanical heart valves can occur and can be critical.
