Curved Bistable Origami‐Inspired Flexible Transcatheter Mitral Valve Clamping

Advanced Science, EarlyView.
A lightweight bistable curved origami dilator combines reversible deformation and high stability, offering a promising solution for minimally invasive mitral valve repair. Abstract Curved origami exhibits remarkable potential for minimally invasive medical applications owing to its unique geometric programmability and mechanical tunability. Building on

Towards Phenotyping Characteristics and Mechanism of Conduction Delay in Patients With Nonischemic Heart Failure With Reduced Ejection Fraction: Insights From Cardiac Magnetic Resonance Imaging

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Considering that 30% to 40% of patients do not benefit from cardiac resynchronization therapy implantation, it is insufficient to evaluate patients with heart failure with reduced ejection fraction solely based on QRS duration and morphology ...

Microgel‐Based Hierarchical Porous Hydrogel Patch with Adhesion and Resilience for Myocardial Infarction

Advanced Science, EarlyView.
This study develops a hierarchically porous hydrogel patch strategy (HPMP), based on gas‐shearing microfluidics and an aqueous two‐phase system to fabricate porous microgels as microgel‐based bioinks. The porous microgels with controllable porous structure exhibit excellent cellular behavior.

Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricle

Cardiovascular Ultrasound, 2006
Background The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering ...

Chaperone‐Mediated Autophagic Degradation of USP9X in Macrophages Exacerbates Postmyocardial Infarction Inflammation and Cardiac Dysfunction

Advanced Science, EarlyView.
This study demonstrates that inflammatory stimuli induce the acetylation‐triggered, chaperone‐mediated autophagic degradation of ubiquitin‐specific peptidase 9 X‐linked (USP9X) in macrophages. USP9X acts as a macrophage “inflammation switch” after myocardial infarction (MI). USP9X loss destabilizes tumor necrosis factor receptor‐associated factor (TRAF)

TRIM40 Drives Pathological Cardiac Hypertrophy and Heart Failure via Ubiquitination of PKN2

Advanced Science, EarlyView.
This study identifies the E3 ligase TRIM40 as a key driver of pathological cardiac hypertrophy. TRIM40 binds PKN2 via its B‐box domain and, through its C29‐dependent catalytic activity, mediates K63‐linked ubiquitination of PKN2. This modification enhances PKN2 phosphorylation at Ser815, thereby driving hypertrophy.
