Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]

, 2001
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

An investigation of the anisotropic mechanical properties and anatomical structure of porcine atrioventricular heart valves.

Journal of The Mechanical Behavior of Biomedical Materials, 2018
Valvular heart diseases are complex disorders, varying in pathophysiological mechanism and affected valve components. Understanding the effects of these diseases on valve functionality requires a thorough characterization of the mechanics and structure ...

Twisted atrioventricular connections in double inlet right ventricle: evaluation by magnetic resonance imaging [PDF]

, 2000
Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed

Late recovery of atrioventricular conduction after postsurgical chronic atrioventricular block is not exceptional [PDF]

, 2013
ObjectivePostsurgical atrioventricular block may complicate surgery for congenital heart defects and is generally considered permanent when persisting longer than 14 days after surgery.

A contact formulation based on a volumetric potential: Application to isogeometric simulations of atrioventricular valves

Computer Methods in Applied Mechanics and Engineering, 2017
This work formulates frictionless contact between solid bodies in terms of a repulsive potential energy term and illustrates how numerical integration of the resulting forces is computationally similar to the “pinball algorithm” proposed and studied by ...

The Homozygous p.(Arg215Ter) Variant in XRCC2 Is Associated With Atypical Fanconi Anemia Without Major Hematological Abnormalities in Childhood

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Fanconi Anemia (FA) is the most frequent inherited bone marrow failure syndrome. A role for the XRCC2 gene in FA was suspected in 2012 and confirmed in 2016, but only two affected individuals have been described thus far, and no long‐term follow‐up is available.

The sophisticated architecture of the rat atrioventricular node [PDF]

, 2005
In the mammalian heart, the action potential spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node.

Worsening Heart Failure From Decreased Atrioventricular Synchronization Rate of a Leadless Pacemaker

JACC: Case Reports
Background: Atrioventricular synchronous pacing with a leadless pacemaker is a therapy used in patients with atrioventricular block. However, atrial oversensing may cause an increase in heart rate, with resulting atrioventricular dyssynchrony.

Co‐Occurring Non‐Cardiac Congenital Anomalies Among Cases With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cases with congenital heart defects (CHD) often have other associated anomalies. The aim of this investigation was to assess the prevalence and the types of co‐occurring anomalies in CHD in a well‐defined population. The anomalies co‐occurring with CHD were ascertained in all live births, stillbirths and terminations of pregnancy for fetal ...
