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 ...

Degenerative processes in bioprosthetic mitral valves in juvenile pigs

Journal of Cardiothoracic Surgery, 2011
Background Glutaraldehyde-treated bioprosthetic heart valves are commonly used for replacement of diseased heart valves. However, calcification and wear limit their durability, and the development of new and improved bioprosthetic valve designs is needed

Mitral Valve Repair in Children With Rheumatic Heart Disease [PDF]

ACC Current Journal Review, 2005
The purpose of this study was to assess the long-term results of mitral valve repair in children with chronic rheumatic heart disease.From January 1988 through December 2003, 278 children (153 male children) underwent mitral valve repair. Mean age was 11.7 +/- 2.9 years (range, 2-15 years).

Study of the normal heart size in Northwest part of Iranian population: a cadaveric study [PDF]

Journal of Cardiovascular and Thoracic Research, 2016
Introduction: The heart is in a muscular organ in the middle mediastinum. According to our knowledge, there is no standard data about the anthropologic parameters of normal Iranian hearts. Hence, the aim of the present study was to investigate the normal

Diagnosis of mitral insufficiency using impedance cardiography technique ICG

Journal of Electrical Bioimpedance, 2016
Impedance cardiography (ICG) is a non-invasive tool for assessing the hemodynamic parameters. It has been used for diagnosing several cardiovascular diseases, such as heart failure, cardio-myopathy, and valvular diseases. Particularly, the valvular heart

Is rheumatic aetiology a predictor of poor outcome in the current era of mitral valve repair? Contemporary long-term results of mitral valve repair in rheumatic heart disease.

European Journal of Cardio-Thoracic Surgery, 2013
OBJECTIVES Contemporary experience with mitral valve (MV) repair in the rheumatic population is limited. We aimed to examine the long-term outcomes of rheumatic MV repair, to identify the predictors of durability and to compare the repair for rheumatic ...
