Three dimensional echocardiography in congenital heart defects

open access: yesAnnals of Pediatric Cardiology, 2008
Three dimensional echocardiography (3DE) is a new, rapidly evolving modality for cardiac imaging. Important technological advances have heralded an era where practical 3DE scanning is becoming a mainstream modality. We review the modes of 3DE that can be

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

open access: yesAdvanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

open access: yesAdvanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

Longitudinal Echocardiographic Surveillance of Aortic Dilation in a Phenotype‐Enriched Turner Syndrome Cohort

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...

Mitral valvuloplasty using real‐time three‐dimensional transesophageal echocardiography

open access: yesAnnals of Noninvasive Electrocardiology
Objective This study aimed to investigate the structure of the mitral valve in patients undergoing mitral valvuloplasty (MVP) using real‐time three‐dimensional transesophageal echocardiography (RT‐3D‐TEE). The main objective was to study the relationship

Refining a preclinical model of viral myocarditis in accordance with biotech standards

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study aimed to refine a murine model of Coxsackievirus B3‐induced myocarditis by integrating dietary and imaging innovations to improve animal welfare, data quality, and clinical applicability. The refined diet significantly reduced animal health burden, reduced weight loss, and stabilized blood glucose during development of cardiac inflammation ...

Glycopolymeric nanoparticles transported by activated platelets protect ischemic myocardium by alleviating PANoptosis through targeting macrophage Dectin‐1

open access: yesBMEMat, EarlyView.
NP‐SF, designed to target macrophage Dectin‐1 and activated platelets, selectively accumulated in ischemic myocardium, where it was taken up by macrophages after platelet hitchhiking. By inhibiting NLRC5‐related PANoptosis, NP‐SF significantly attenuated pathological damage, and effectively preserved cardiac function in a murine ischemia–reperfusion ...
