Frontiers in Cardiovascular Medicine, 2016 Mitral stenosis (MS) after mitral valve (MV) repair is a slowly progressive condition, usually detected many years after the index MV surgery. It is defined as a mean transmitral pressure gradient (TMPG) >5 mmHg or a mitral valve area (MVA)

The Egyptian Heart Journal, 2015 Introduction: The tricuspid valve (TV) is a complex structure (Lamers et al. (1995) [1]). The most common cause of pathologic tricuspid regurgitation is functional, due to annular dilatation with normal leaflet morphology (Sagie et al.

Degenerative Mitral Stenosis—Diagnostic Challenges and Future Directions
Reviews in Cardiovascular Medicine, 2022 Determining the severity of stenosis in degenerative mitral stenosis (DMS) is fraught with challenges. Neither a high trans-mitral gradient nor a small valve area calculation is sufficiently diagnostic for DMS due to variable left atrial and left ...

Correlation between Mitral Valve Area and Right Ventricle Function based on TAPSE (Tricuspid Annular Plane Systolic Excursion) Parameter in Mitral Stenosis Patient [PDF]
, 2018 Background: Mitral stenosis is the most common mitral valve disease found in Indonesia. Mechanical obstruction of blood flow from left atrium to left ventricle is compensated by pressure elevation in the left atrium and pulmonary circulation. It leads to

CardioXNet: A Novel Lightweight Deep Learning Framework for Cardiovascular Disease Classification Using Heart Sound Recordings [PDF]
, 2020 The alarmingly high mortality rate and increasing global prevalence of cardiovascular diseases signify the crucial need for early detection schemes. Phonocardiogram (PCG) signals have been historically applied in this domain owing to its simplicity and cost-effectiveness.

Plasma lipids and risk of aortic valve stenosis: a Mendelian randomization study
European Heart Journal, 2020 Aims Aortic valve stenosis is commonly considered a degenerative disorder with no recommended preventive intervention, with only valve replacement surgery or catheter intervention as treatment options.

The effects of leaflet material properties on the simulated function of regurgitant mitral valves [PDF]
, 2023 Advances in three-dimensional imaging provide the ability to construct and analyze finite element (FE) models to evaluate the biomechanical behavior and function of atrioventricular valves. However, while obtaining patient-specific valve geometry is now possible, non-invasive measurement of patient-specific leaflet material properties remains nearly ...

Journal of the Practice of Cardiovascular Sciences, 2022 Very little is known about the occurrence of bioprosthetic tricuspid valve stenosis in the Indian population that usually occurs within 8–10 years following tricuspid valve replacement (TVR) with a bioprosthetic valve.

The assessment of mitral valve disease: a guideline from the British Society of Echocardiography
Echo Research and Practice, 2021 Mitral valve disease is common. Mitral regurgitation is the second most frequent indication for valve surgery in Europe and despite the decline of rheumatic fever in Western societies, mitral stenosis of any aetiology is a regular finding in all echo ...
