SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development. [PDF]

Anat Rec (Hoboken)
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Mitral Valve Interventions in Heart Failure [PDF]

ESC Heart Failure, 2018
Abstract Secondary 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
Abstract Mitral 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 ...

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).

Pseudo-double orifice mitral valve or heart in heart mitral valve

Journal of Indian College of Cardiology, 2016
Abstract Pseudo-double orifice mitral valve is a condition characterised by double orifice appearance of mitral valve and it occurs as a result of acquired heart disease. This article describes echocardiographic appearance of this condition and helps in differentiating from double orifice mitral valve.

Quadrivalvular rheumatic heart disease

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019
Rarely, rheumatic heart disease (RHD) involves all the four valves and causes could be rheumatic, congenital, infective, or degenerative. Here, we report a case of a 42-year-old female known case RHD for 30 years and underwent closed mitral ...

Beating-heart mitral valve chordal replacement [PDF]

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Replacing open-heart surgical procedures with beating-heart interventions substantially decreases the trauma and risk of a procedure. One of the most challenging procedures to perform on the beating heart is valve repair. To address this need, this paper proposes a tool for replacing mitral valve chordae to correct regurgitation. The chordae is secured

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

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.

Image Segmentation for Mitral Regurgitation with Convolutional Neural Network Based on UNet, Resnet, Vnet, FractalNet and SegNet: A Preliminary Study

Big Data and Cognitive Computing, 2022
The heart’s mitral valve is the valve that separates the chambers of the heart between the left atrium and left ventricle. Heart valve disease is a fairly common heart disease, and one type of heart valve disease is mitral regurgitation, which is an ...

Study of mitral valve in human cadaveric hearts

Heart Views, 2012
The mitral valve is a complex structure that is altered by disease states. The classical image of the mitral valve is a bicuspid valve with two leaflets and two papillary muscles. The reason for the present study is to study the morphology and morphometry of the mitral valve.This study was carried out on 116 human cadaveric hearts.
