Biodegradable and Edible Milli‐Fluidic Logic Circuits

open access: yesAdvanced Materials Technologies, EarlyView.
Fully biodegradable and edible fluidic circuits are developed using gelatin‐based valves that operate at low pressure. Logic gates, a one‐bit memory, and a ring oscillator are demonstrated, showing that biodegradable materials can perform computation and control.

Liquid Metal Resistive Sensing Architectures for Measuring Diaphragm Strain Responses on Obstructed Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
A liquid metal‐based strain‐sensing architecture to measure the deformation of a circular diaphragm against obstructed surfaces is formulated using finite element modeling and confocal imaging to establish the mechanical framework and is utilized to control diaphragm‐induced confinement on a bead array, as validated by biomolecular loading level ...

Echocardiographic navigation in transapical neochord mitral valve repair with significant mitral regurgitation

open access: yesВестник хирургии имени И.И. Грекова
INTRODUCTION. Significant mitral regurgitation is currently a widespread acquired valvular heart disease and is associated with a significant decrease in survival and deterioration in quality of life. One of the new, unclearly studied, minimally invasive

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Comparison of robotic and anterolateral minithoracotomy mitral valve repair: Experience in ChinaCentral MessagePerspective

open access: yesJTCVS Open
Objective: Nonsternotomy mitral valve repair is a popular treatment for degenerative mitral regurgitation. Data on the safety and effectiveness of anterolateral minithoracotomy and robotic mini-invasive mitral valve repair are lacking in China.

Management of functional tricuspid regurge during mitral valve replacement, DeVega versus Bicuspidization repair. [PDF]

open access: yesAl-Azhar International Medical Journal
Background: Rheumatic mitral valve disease (stenosis or regurgitation) is mostly associated with secondary (functional) tricuspid valve regurgitation due to tricuspid annular dilatation that needs to be repaired (during mitral valve replacement) through ...

Isolated surgical tricuspid repair versus replacement: meta-analysis of 15 069 patients

open access: yesOpen Heart, 2020
ObjectivesTricuspid valve disease is increasingly encountered, but surgery is rarely performed in isolation, in part because of a reported higher operative risk than other single-valve operations.

The Perceval Sutureless Valve in Aortic Root Reoperation

open access: yes, 2017
The case is reported of a 62-year-old man with severe aortic regurgitation that was related to failed prior valve-sparing ascending aortic aneurysm repair, and who was successfully treated with a Perceval Sutureless ...

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Longitudinal Outcomes Following Mitral Valve Repair for Infective Endocarditis

open access: yesMicroorganisms
Mitral valve repair is the ideal approach in managing mitral valve infective endocarditis for patients requiring surgery. However, viable repair is influenced by the extent of valve destruction and there can be technical challenges in reconstruction ...
