A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

F‐Box and Leucine‐Rich Repeat Protein 4 (FBXL4) Maintains Sarcomere Integrity and Cardiac Function by Enhancing K48‐Linked Ubiquitinated Degradation of Profilin‐1 (PFN1)

Advanced Science, EarlyView.
Schematic diagram depicting the proposed signaling mechanisms underlying the effects of FBXL4 in the setting of cardiac hypertrophy. Under hypertrophic stimulation, cardiomyocytes‐specific overexpression FBXL4 maintains sarcomere integrity and cardiac function by enhancing K48‐linked ubiquitinated degradation of PFN1 at the K70 site.

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

, 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.

Transplante de valva mitral heteróloga: Nova alternativa cirúrgica: estudo clínico inicial Heterologous mitral valve transplant: New surgical technique: initial clinical trial

Brazilian Journal of Cardiovascular Surgery, 1993
A substituição da valva mitral tem sido realizada, nestes 30 anos, usando-se o modelo aórtico. Embora o resultado clínico, na maioria dos pacientes seja satisfatório, existem, restrições específicas, tanto entre as biopróteses, como nas próteses ...

A Rare Culprit of Infective Endocarditis in an IV Drug User: Burkholderia cepacia

Case Reports in Medicine, 2019
Infective endocarditis (IE) is an infection of the cardiac native or prosthetic valves typically caused by Staphylococcus aureus, viridans streptococci group, and coagulase-negative staphylococci. Risk factors include congenital heart disease, structural

"Pac-Man Heart" and Mitral Valve Prolapse

Journal of Cardiovascular Echography, 2021
A 50-year-old man accessed the echo laboratory for dyspnea. His medical history was unremarkable. Transthoracic two-dimensional echocardiogram showed a posterior leaflet of the mitral valve prolapse associated with eccentric regurgitant jet.

Reconstructing Coherent Functional Landscape From Multi‐Modal Multi‐Slice Spatial Transcriptomics by a Variational Spatial Gaussian Process

Advanced Science, EarlyView.
This study introduces stVGP, a variational spatial Gaussian process framework for multi‐modal, multi‐slice spatial transcriptomics. By integrating histological and genomic data through hybrid alignment and attention‐based fusion, stVGP reconstructs coherent 3D functional landscapes.

Automatic calcium scoring in low-dose chest CT using deep neural networks with dilated convolutions

, 2018
Heavy smokers undergoing screening with low-dose chest CT are affected by cardiovascular disease as much as by lung cancer. Low-dose chest CT scans acquired in screening enable quantification of atherosclerotic calcifications and thus enable ...
