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.

Conceiving MitraClip as a tool: percutaneous edge-to-edge repair in complex mitral valve anatomies.
European Heart Journal-Cardiovascular Imaging, 2020 Improvements in procedural technique and intra-procedural imaging have progressively expanded the indications of percutaneous edge-to-edge technique. To date in higher volume centres and by experienced operators MitraClip is used for the treatment of ...

Mitral valve perforation from aortic insufficiency [PDF]
Anadolu Kardiyoloji Dergisi/The Anatolian Journal of Cardiology, 2013 A 60-year-old man with a history of endocarditis presented with congestive heart failure New York Heart Association class III symptoms. He did not have any signs or symptoms of microembolic phenomenon and the blood cultures were negative. A transesophageal echocardiogram showed an eccentric jet of mitral regurgitation (MR) from a perforation in the ...

An Early Prosthetic Valve Endocarditis in Presence of COVID-19-Associated Pneumonia
Український журнал серцево-судинної хірургії, 2023 Introduction. Coronavirus disease (COVID-19)-associated pneumonia was a dangerous disease at the beginning of 2021. However, there are almost no records of early infectious endocarditis of prosthetic heart valve in the presence of such a disease.

ANZ Journal of Surgery, Volume 92, Issue 12, Page 3154-3161, December 2022., 2022 Analysis of multi‐institutional data and benchmarking is an accepted accreditation standard in cardiac surgery. Such a database does not exist for congenital cardiac surgery in Australia and New Zealand (ANZ). To fill this gap, the ANZ Congenital Outcomes Registry for Surgery (ANZCORS) was established in 2017.

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 ...

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.

Artificial Organs, Volume 47, Issue 1, Page 168-179, January 2023., 2023 Peak oxygen consumption, VO2peak, was associated with short‐term 3‐months‐rehospitalization in heart failure patients with reduced ejection fraction (HFrEF). Exercise oscillatory ventilation (EOV), representing fluctuations of pulmonary artery pressure, can be observed in heart failure patients with reduced ejection fraction with and without left ...
