Atrioventricular canal defect and genetic syndromes: the unifying role of sonic hedgehog [PDF]

, 2019
The atrioventricular canal defect (AVCD) is a congenital heart defect (CHD) frequently associated with extracardiac anomalies (75%). Previous observations from a personal series of patients with AVCD and "polydactyly syndromes" showed that the distinct ...

The anatomy of interatrial communications - what does the interventionist need to know? [PDF]

, 2008
Increasingly, the interventional cardiologist is seeking to close interatrial communications by inserting devices by means of catheterisation. So as to optimise these procedures, it is adavantageous to have a firm grasp of the anatomy of the normal ...

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

Journal 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

Journal 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.

Fetal heterotaxy with tricuspid atresia, pulmonary atresia, and isomerism of the right atrial appendages at 22 weeks. [PDF]

, 2013
We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex ...

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

Annals 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 ...

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]

, 2000
During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.

Syncope and paroxysmal atrioventricular block

Journal of Arrhythmia, 2017
Current literature reveals three types of paroxysmal atrioventricular block (AVB) that can cause syncope:Intrinsic paroxysmal atrioventricular block is due to an intrinsic disease of the AV conduction system; this type of “cardiac syncope” is also ...

Assessment of Atrioventricular Septal Defect on Echocardiography

Journal 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 ...
