Interactive-Automatic Segmentation and Modelling of the Mitral Valve [PDF]
, 2019 Mitral valve regurgitation is the most common valvular disease, affecting 10% of the population over 75 years old. Left untreated, patients with mitral valve regurgitation can suffer declining cardiac health until cardiac failure and death. Mitral valve repair is generally preferred over valve replacement. However, there is a direct correlation between

Modeling the Mitral Valve [PDF]
arXiv, 2022 This thesis 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 attached to a ring, the free edges of which are supported by a system of chordae, which themselves are anchored to muscles inside the heart.

AnimalsMitral valve disease is a common heart disease in dogs. The aim of this study was to describe the cases of dogs that underwent mitral valve repair via a V-clamp device and to provide long-term follow-up data on cardiac function after mitral valve repair.

Anomalous left coronary artery from the pulmonary artery: Outcomes and management of mitral valve
Frontiers in Cardiovascular Medicine, 2022 ObjectiveUse of concomitant mitral valve repair remains controversial in the anomalous left coronary artery from the pulmonary artery (ALCAPA) with mitral regurgitation (MR).

CNN-based fully automatic mitral valve extraction using CT images and existence probability maps [PDF]
arXiv, 2023 Accurate extraction of mitral valve shape from clinical tomographic images acquired in patients has proven useful for planning surgical and interventional mitral valve treatments. However, manual extraction of the mitral valve shape is laborious, and the existing automatic extraction methods have not been sufficiently accurate.

Computational fluid dynamics modelling of left valvular heart diseases during atrial fibrillation [PDF]
PeerJ, 4: e2240, 2016, 2016 Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics.

Annals of Cardiac Anaesthesia, 2015 Mitral valve disease is common in the United States and around the world, and if left untreated, increases cardiovascular morbidity and mortality. Mitral valve repair is technically more demanding than mitral valve replacement. Mitral valve repair should

Flexible and Comprehensive Patient-Specific Mitral Valve Silicone Models with Chordae Tendinae Made From 3D-Printable Molds [PDF]
, 2019 Given the multitude of challenges surgeons face during mitral valve repair surgery, they should have a high confidence in handling of instruments and in the application of surgical techniques before they enter the operating room. Unfortunately, opportunities for surgical training of minimally-invasive repair are very limited, leading to a situation ...

Simplified ELASTA-CLIP Before Transapical Mitral Valve Replacement
JACC: Case Reports, 2023 Residual and recurrent mitral regurgitation after transcatheter edge-to-edge repair are therapeutically challenging. In the present case report, we describe a simplified, transapical electrosurgical laceration and stabilization of clip procedure that ...

Comparison of Depth Estimation Setups from Stereo Endoscopy and Optical Tracking for Point Measurements [PDF]
arXiv, 2022 To support minimally-invasive intraoperative mitral valve repair, quantitative measurements from the valve can be obtained using an infra-red tracked stylus. It is desirable to view such manually measured points together with the endoscopic image for further assistance.
