Novel 3-dimensional effective regurgitation orifice area quantification serves as a reliable tool to identify severe mitral valve regurgitation

open access: yesScientific Reports
A precise quantification of mitral regurgitation (MR) severity is essential for treatment and outcome of patients with MR. 3D echocardiography facilitates estimation of MR but selection of patients with necessity of invasive treatment remains challenging.

EVALUATION OF RIGHT VENTRICLE SYSTOLIC AND DIASTOLIC FUNCTION IN PATIENTS WITH PAROXYSMAL ATRIAL FIBRILLATION

open access: yesSanamed, 2020
Objective: Atrial fibrillation (AF) is frequently an electrical sign of underlying structural heart disease. Structural remodelling may begin not only in ventricles but also in atrium secondary to AF. In this study, we sought to investigate the effect of

Feature detection from echocardiography images using local phase information [PDF]

open access: yes, 2008
Ultrasound images are characterized by their special speckle appearance, low contrast, and low signal-to-noise ratio. It is always challenging to extract important clinical information from these images.

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.

Is follow-up echocardiogram mandatory after a STEMI?

open access: yesEcho Research and Practice, 2020
Current guidelines do not advise follow-up echocardiograms after ST-segment elevation myocardial infarction (STEMI), unless the left ventricular ejection fraction is ≤40%.

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 ...

Macrophage GLUD1 is Essential for Redox Balance and Immune Homeostasis in Cardiac Injury

open access: yesAdvanced Science, EarlyView.
Excessive free radical production and dysregulated immune responses are key contributors to myocardial ischemia‐reperfusion (IR) injury. Macrophage GLUD1 activity safeguards against HIF‐1α accumulation and maladaptive responses to IR‐induced ROS production.
