Clarifying the atrioventricular junctional anatomy in the setting of double outlet right atrium

open access: yesAnnals of Pediatric Cardiology, 2015
Double outlet atrium is a rare cardiac anomaly wherein one of the atriums, most frequently the right atrium, opens into both the ventricles. Although seen more commonly in the setting of atrioventricular septal defect, this arrangement can also be found ...

Assessment of Atrioventricular Septal Defect on Echocardiography

open access: yesJournal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2020
Atrioventricular septal defect comprise of 1.4-2.9% of congenital cardiac defect and is most common congenital cardiac defect in Trisomy 21. This anomaly is characterized by a common atrioventricular junction coexisting with atrial and/or ventricular ...

Unravelling Atrioventricular Block Risk in Inflammatory Diseases: Systemic Inflammation Acutely Delays Atrioventricular Conduction via a Cytokine‐Mediated Inhibition of Connexin43 Expression

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Recent data suggest that systemic inflammation can negatively affect atrioventricular conduction, regardless of acute cardiac injury.

Electrophysiology Study for Complex Supraventricular Tachycardia in Congenital Heart Disease Patients With Single‐Ventricle Physiology

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundSupraventricular tachycardia (SVT) is common in complex congenital heart disease (CCHD) patients with single‐ventricle physiology and may cause hemodynamic deterioration.

Implantation of atrioventricular synchronous and atrioventricular universal pacemakers

open access: yesThe Journal of Thoracic and Cardiovascular Surgery, 1983
Implantation of pacemakers which sense in the atrium and the ventricle requires understanding of both antegrade conduction, from the atrium to the ventricle, and retrograde conduction, from the ventricle to the atrium. Of 53 patients undergoing pacemaker implantation, 25 (47%) had retained VA conduction and 25% of those with complete heart block had 1 ...

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

open access: yesAdvanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Paradoxical heart rate response after atropine sulfate administration in total atrioventricular block complicating acute myocardial infarction: A case report

open access: yesBali Journal of Anesthesiology, 2021
Acute myocardial infarction is sometimes complicated by atrioventricular block. Advanced cardiac life support guideline for the treatment of atrioventricular block suggests early use of atropine.

The Deubiquitinase UCHL1 Drives Susceptibility to Atrial Fibrillation by Stabilizing CaMKII‐δ

open access: yesAdvanced Science, EarlyView.
UCHL1 is highly upregulated in mice and patients with AF. UCHL1 directly binds to and removes K48‐linked polyubiquitin chains from CaMKII‐δ at K251 and enhances CaMKII‐δ stability, which activates RyR2, disrupts Ca2+ handling, and promotes AF. These findings establish UCHL1 as a critical regulator of CaMKII‐δ stability and AF‐related Ca2+ handling ...

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
