Modeling the Mitral Valve [PDF]

International Journal for Numerical Methods in Biomedical Engineering, 2019
This work 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, the free edges of which are supported by a system of chordae, which themselves are anchored to the papillary muscles inside the left ventricle.

Effect of concurrent mitral valve surgery for secondary mitral regurgitation upon mortality after aortic valve replacement or coronary artery bypass surgery [PDF]

Frontiers in Cardiovascular Medicine, 2023
ObjectivesIt is uncertain whether concurrent mitral valve repair or replacement for moderate or greater secondary mitral regurgitation at the time of coronary artery bypass graft or aortic valve replacement surgery improves long-term survival ...

Mitral valve and mitral valve disease [PDF]

BJA Education, 2017
### Key points The mitral valve separates the left atrium from the left ventricle (LV) and, as such, is an integral part of the high-pressure systemic circulation. Therefore, any pathology of the valve can have critical physiological effects that the anaesthetist must be aware of. Anaesthesia alters the way in which the heart, valve, and circulation

Mitral valve repair [PDF]

F1000Research, 2016
Mitral regurgitation (MR) is the most common valvular heart disease in the Western world. The MR can be either organic (mainly degenerative in Western countries) or functional (secondary to left ventricular remodeling in the context of ischemic or idiopathic dilated cardiomyopathy).

Parachute mitral valve

Annals of Cardiac Anaesthesia, 2021
An asymptomatic 30-year-old male was referred for a transthoracic echocardiogram because of a systolic murmur that was noted on a pre-employment physical exam. Transthoracic imaging demonstrated a single papillary muscle from which the chordae of both mitral valve leaflets were attached.

Estimation of mitral valve hinge point coordinates -- deep neural net for echocardiogram segmentation [PDF]

Computer Science Research Notes , CSRN 3201, 2022, ISSN 2464-4617, 2023
Cardiac image segmentation is a powerful tool in regard to diagnostics and treatment of cardiovascular diseases. Purely feature-based detection of anatomical structures like the mitral valve is a laborious task due to specifically required feature engineering and is especially challenging in echocardiograms, because of their inherently low contrast and

Echocardiographic description and outcomes in a heterogeneous cohort of patients undergoing mitral valve surgery with and without mitral annular disjunction: a health service evaluation

Echo Research and Practice, 2022
Background Mitral annular disjunction (MAD) is a structural abnormality characterized by the distinct separation of the mitral valve annulus/left atrium wall and myocardium. Little is known about the significance of MAD in patients requiring mitral valve

Anatomy of the mitral valve: understanding the mitral valve complex in mitral regurgitation [PDF]

European Journal of Echocardiography, 2010
Imaging the mitral valve requires an understanding of the normal anatomy and how this complex structure is altered by disease states. Mitral regurgitation is increasingly prevalent. Despite the fall in rheumatic disease, it is the second most common valvular lesion seen in adults in Europe.

Surgical treatment of mitral valve insufficiency by valve repair [PDF]

Brazilian Journal of Cardiovascular Surgery, 2002
OBJECTIVE: To analyze the short term results of mitral valve repair in a consecutive series of mitral insufficiency patients from different ethiologies. METHODS: A retrospective study was made of 86 patients with mitral insufficiency operated on between ...

Presence Of A Congenitally Bicuspid Aortic Valve Among Patients Having Combined Mitral And Aortic Valve Replacement [PDF]

, 2012
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent.
