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

Mapping of mitral regurgitant defects by cardiovascular magnetic resonance in moderate or severe mitral regurgitation secondary to mitral valve prolapse

Journal of Cardiovascular Magnetic Resonance, 2008
Purpose In mitral valve prolapse, determining whether the valve is suitable for surgical repair depends on the location and mechanism of regurgitation.

Acquired heart defects: Clinical picture, diagnosis [PDF]

BIO Web of Conferences, 2023
In acquired heart defects, they are defined as the occurrence of an irreversible violation in its structure, that leads to a complete loss of its function, changes in intracardiac hemodynamics, as well as change in intracardiac hemodynamics, as a result ...

Anomalous origin of the left coronary artery from the pulmonary artery as a rare cause of mitral valve prolapse: a case report

BMC Cardiovascular Disorders, 2022
Background  Mitral valve prolapse (MVP) is an etiologically heterogeneous disorder. Early diagnosis and prompt treatment of the underlying disease are of great significance.

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

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

Clinical-echocardiographic Diagnostics of Mitral Valve Prolapse Origin in Children

Zdorovʹe Rebenka, 2014
With the purpose to determine hemodynamic and morphometric features of mitral valve prolapse of inflammatory and non-inflammatory genesis by means of dopplerechocardiography 34 children ageв of 5–17 years old were observed. The children with mitral valve

Massive Hemoptysis due to Acute Mitral Regurgitation with Sporadic Primary Mitral Valve Prolapse [PDF]

Korean Journal of Critical Care Medicine, 2015
The most common cardiac cause of massive hemoptysis is mitral stenosis. Mitral regurgitation is rarely complicated by massive hemoptysis. A 48-year-old man with no significant medical history was admitted to our hospital with hemoptysis and production of
