A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

open access: yesAdvanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Echocardiography 2020: Toward deciphering the “Rosetta stone” of left ventricular diastolic function

open access: yes, 2020
In the year 1997, nearly a quarter-century ago, Nishimura and Tajik (J Am Coll Cardiol. 1997;30:8) suggested that Doppler echocardiography was the "Rosetta stone" (a metaphor for decrypting secrets of diastole) of left ventricular diastole, based solely ...

Alkylating Agent–Induced FANCL Impairment Damages Pulmonary Arterial, Venous, and Microvascular Endothelial Cells and Predisposes to PAH/PVOD

open access: yesAdvanced Science, EarlyView.
This study establishes a novel cisplatin‐induced rat model of PAH/PVOD and identifies a conserved mechanistic axis—FANCL impairment, DNA damage accumulation, and endothelial dysfunction—triggered by cisplatin or mitomycin C across pulmonary arteries, veins, and microvessels.

Evaluation of left atrial volume and function using single-beat real-time three-dimensional echocardiography in atrial fibrillation patients

open access: yesBMC Medical Imaging, 2017
Background This study was aimed to evaluate the feasibility and accuracy of real-time three-dimensional echocardiography (RT-3DE) measurement of left atrial (LA) volume and function in comparison with two-dimensional echocardiography (2DE) measurements ...

Alteration of Surgical Management Following Intraoperative Transesophageal Echocardiography in a Patient With Mobile Left Atrial Thrombi Embolized During Anesthesia

open access: yes, 2003
This report describes alteration of surgical management in a patient with a large free-floating ball thrombus in the left atrium, which was embolized before sternotomy as demonstrated by intraoperative transesophageal echocardiography.

Targeting Nupr1‐Mediated p53 Mitochondrial Sequestration Alleviates Aortic Dissection by Restoring the Gadd45b‐Dependent Survival Program

open access: yesAdvanced Science, EarlyView.
This study identifies Nupr1 as a crucial stress‐responsive orchestrator driving AD. Under severe stress, Nupr1 massively accumulates within mitochondria to sequester p53, triggering apoptosis and concurrently repressing the Gadd45b‐mediated survival program.

Ultrasound‐Triggered piRNA Delivery Using Biomimetic Phase‐Changeable Nanoparticles for Theranostics of Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
A biomimetic ultrasound‐responsive piRNA delivery nanoparticle platform (piR‐NPs) enables targeted delivery and ultrasound (US)‐triggered release of piR‐1873 in infarcted myocardium. The released piR‐1873 suppresses Usp2‐mediated RIP1/RIP3/MLKL necroptosis, reduces myocardial injury and fibrosis, and promotes cardiac functional recovery, providing a ...
