Outcomes after bioprosthetic versus mechanical mitral valve replacement for infective endocarditis in the United StatesCentral MessagePerspective

open access: yesJTCVS Open
Objective: In patients who underwent mitral valve replacement for infectious endocarditis, we evaluated the association of prosthesis choice with readmission rates and causes (the primary outcomes), as well as with in-hospital mortality, cost, and length

Isolated non-obstructive accessory mitral valve tissue in an adult mimicking ruptured chordae

open access: yesIndian Heart Journal, 2013
Accessory mitral valve tissue is commonly associated with other congenital heart diseases and is usually detected in children causing left ventricular outflow tract obstruction.

Mitral Valve Prolapse, Ventricular Arrhythmias, and Sudden Death.

open access: yesCirculation, 2019
Despite a 2% to 3% prevalence of echocardiographically defined mitral valve prolapse (MVP) in the general population, the actual burden, risk stratification, and treatment of the so-called arrhythmic MVP are unknown. The clinical profile is characterized

Outcomes of transcatheter mitral valve replacement for degenerated bioprostheses, failed annuloplasty rings, and mitral annular calcification

open access: yesEuropean Heart Journal, 2018
Aims We sought to evaluate the outcomes of transcatheter mitral valve replacement (TMVR) for patients with degenerated bioprostheses [valve-in-valve (ViV)], failed annuloplasty rings [valve-in-ring (ViR)], and severe mitral annular calcification [valve ...

Performance evaluation on mitral valve motion feature tracking using Kanade-Lucas- Tomasi (KLT) algorithm based eigenvalue measurement [PDF]

open access: yes, 2019
This paper provides the explanation of the concepts of point tracking technique to be implemented in mitral valve locating in video frames. Object tracking has been used for many applications in motion-based recognition and monitoring.

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Left atrial anomalous muscular band as incidental finding during video-assisted mitral surgery [PDF]

open access: yes, 2018
Congenital fibromuscular bands have been described inleft ventricle or right atrium and have been diagnosed by echocardiography and CT scan. The first report of anomalous band in the left atrium was described in 1897 by Rollestone (1).

Primary cilia defects causing mitral valve prolapse

open access: yesScience Translational Medicine, 2019
Genetic variations in primary cilia genes cause defects during valve morphogenesis that can progress to mitral valve prolapse in the adult. DZIPping along to diagnosis Mitral valve prolapse is a common congenital abnormality that can cause severe ...

Artificial Nervous Systems

open access: yesAdvanced Science, EarlyView.
By drawing inspiration from biological neural hierarchies and the working mechanisms of plasticity, researchers have constructed a series of bionic devices, including sensory devices, synapse devices, and artificial neural systems. They committed to simulating and surpassing the biological information processing function, thereby realizing the ...
