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

Improved Heatmap-based Landmark Detection [PDF]
, 2021 Mitral valve repair is a very difficult operation, often requiring experienced surgeons. The doctor will insert a prosthetic ring to aid in the restoration of heart function. The location of the prosthesis' sutures is critical. Obtaining and studying them during the procedure is a valuable learning experience for new surgeons.

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

A retrospective audit of mitral valve repair surgery at Tygerberg Hospital
SA Heart Journal, 2018 Background: Mitral valve repair is well established as the preferred treatment modality for the majority of patients with degenerative mitral valve disease requiring intervention. Valve repair offers a distinct event-free survival advantage compared with

Intensive care and anesthesia management for HARPOON beating heart mitral valve repair
Annals of Cardiac Anaesthesia, 2020 Patients with severe mitral valve regurgitation secondary to degenerative disease are known to benefit from mitral valve repair surgery. Novel techniques for achieving mitral valve repair on the beating heart have been developed and are being introduced ...

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 ...

Евразийский Кардиологический Журнал, 2023 Background. Septal myectomy is currently the «gold» standard of surgical treatment of patients with obstructive hypertrophic cardiomyopathy. In some cases, isolated septal myectomy does not eliminate SAM-induced mitral insufficiency.
