Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

Advanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Minimally Invasive Mitral Valve Repair and Coronary Artery Bypass Graft by a Periareolar Approach

Annals of Thoracic Surgery Short Reports
Use of coronary artery bypass for mitral valve repair in ischemic mitral regurgitation remains controversial. We present a case of a 52-year-old man with significant ischemic mitral regurgitation and coronary artery disease who underwent mitral valve ...

«Edge-to-edge» mitral valve repair for septal myectomy versus isolated myectomy: a pilot randomized trial

Евразийский Кардиологический Журнал, 2023
Background. Septal myectomy  is currently the «gold» standard of surgical treatment  of patients with obstructive  hypertrophic  cardiomyopathy.  In some  cases,  isolated septal myectomy does  not eliminate SAM-induced mitral insufficiency.

Intracardiac Calcification - An Interesting Chest X-ray Report. [PDF]

, 2013
We report a case of chest X-ray finding of mitral annular calcification. Mitral annular calcification is a degenerative process involving the fibrous annulus of the mitral valve.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

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

JTCVS 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.

Mitral annulus morphologic and functional analysis using real time tridimensional echocardiography in patients submitted to unsupported mitral valve repair

Brazilian Journal of Cardiovascular Surgery, 2015
Introduction:Mitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce.Objective:To analyze mitral ...
