Transcatheter aortic valve replacement valve in transcatheter aortic valve replacement valve for severe periprosthetic regurgitation

open access: yesHeart Views, 2020
The management of postprocedure severe aortic periprosthetic regurgitation after transcatheter aortic valve replacement (TAVR) is unknown. While valve-in-valve TAVR has been associated with favorable outcomes for degenerative surgically implanted ...

Experimental investigation of the flow downstream of a dysfunctional bileaflet mechanical aortic valve [PDF]

open access: yesarXiv, 2019
Mechanical heart valve replacement is the preferred alternative in younger patients with severe symptomatic aortic valve disease. However, thrombus and pannus formations are common complications associated with bileaflet mechanical heart valves. This leads to risks of valve leaflet dysfunction, a life threatening event.

A Computational Framework for Atrioventricular Valve Modeling using Open-Source Software [PDF]

open access: yesarXiv, 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 ...

Factors Influencing Mortality after Bioprosthetic Valve Replacement; A Midterm Outcome [PDF]

open access: yesJournal of Cardiovascular and Thoracic Research, 2013
Introduction: Although valve repair is applied routinely nowadays, particularly for mitral regurgitation (MR) or tricuspid regurgitation (TR), valve replacement using prosthetic valves is also common especially in adults.

Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics [PDF]

open access: yesarXiv, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease. However, valves may dysfunction leading to adverse hemodynamic conditions.

Melody Valve for Mitral Valve Replacement [PDF]

open access: yesOperative Techniques in Thoracic and Cardiovascular Surgery, 2014
In certain pediatric patients with irreparable mitral valve disease, mitral valve replacement is necessary. One option for replacement in a child with small annulus is off label use of the Melody valve for mitral replacement. The device modifications and implantation technique are described, and focus on maneuvers to prevent perivalvular leak and left ...

Direct Observation of Dry Etch‐Induced Selectivity Tailoring of Alkylate Inhibition Layer Using DMATMS Vapor

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates that tailoring surface ─OH groups on SiO2 and SiNx via dry etching significantly enhances the selectivity of DMATMS adsorption, achieving a 92.2% selectivity in subsequent Ru layer growth. In situ spectroscopy reveals that removal of ─OH groups reduce DMATMS reactivity on SiNx but not on SiO2, providing insights for improving ...
