Journal of Cardiothoracic Surgery, 2017 Background Valve-in-Valve (VIV) Transcatheter Aortic Valve Replacement (TAVR) is now the treatment of choice in high-surgical-risk patients with failing aortic bioprosthesis. Although less performed, VIV-Transcatheter Mitral Valve Replacement (TMVR) is a

A Computational Framework for Atrioventricular Valve Modeling using Open-Source Software [PDF]
arXiv, 2022 Atrioventricular valve regurgitation is a significant cause of morbidity and mortality in patients with acquired and congenital cardiac valve disease. Image-derived computational modeling of atrioventricular valves has advanced substantially over the last decade and holds particular promise to inform valve repair in small and heterogeneous populations ...

Antithrombotic Treatment After Transcatheter Valve Interventions: Current Status and Future Directions. [PDF]
, 2023 PURPOSE The optimal antithrombotic strategy after transcatheter valve interventions is a subject of ongoing debate. Although there is evidence from randomized trials in patients undergoing transcatheter aortic valve replacement (TAVR), current ...

Modeling the Mitral Valve [PDF]
, 2019 This work 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, the free edges of which are supported by a system of chordae, which themselves are anchored to the papillary muscles inside the left ventricle.

Management of tricuspid regurgitation in patients undergoing mitral valve replacement for rheumatic mitral valve diseases [PDF]
, 2012 BACKGROUND: In mitral valve diseases associated with long standing pulmonary hypertension,Tricuspid annulus dilates and fails to shorten during systole leading to Tricuspid regurgitation.Tricuspid regurgitation contributes to both the morbidity and ...

Sutureless aortic valve replacement in a calcified homograft combined with mitral valve replacement
Journal of Cardiothoracic Surgery, 2017 Background Aortic valve replacement in a patient with an aortic homograft can be very challenging, especially when concomitant mitral valve surgery needs to be performed.

Neural collaborative filtering for unsupervised mitral valve segmentation in echocardiography [PDF]
arXiv, 2020 The segmentation of the mitral valve annulus and leaflets specifies a crucial first step to establish a machine learning pipeline that can support physicians in performing multiple tasks, e.g.\ diagnosis of mitral valve diseases, surgical planning, and intraoperative procedures.

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 ...
