Clarifying the anatomy of the atrioventricular node artery

International Journal of Cardiology, 2018
Reports of conduction abnormalities necessitating permanent pacemaker implantation due to atrioventricular node artery injury and increasing evidence of stenosis of the atrioventricular node artery in cases of sudden death are of unsolved clinical importance.

Re-evaluation of the structure of the atrioventricular node and its connections with the atrium.

Europace, 2020
AIMS The anatomic substrates for atrioventricular nodal re-entry remain enigmatic, but require knowledge of the normal arrangement of the inputs and exist from the atrioventricular node.

Dual atrioventricular nodes [PDF]

Heart, 2014
To the Editor I read with great interest the ‘challenge’ posed by the electrocardiographic recording in issue 7 of Heart for 2014.1 I also noted with interest that the authors suggest that Monckeberg provided the first account of such dual nodes in 1993. Since Monckeberg was long since dead by that date, this must be some mistake!

Mesothelioma of the Atrioventricular Node

Chest, 1973
In a 17-year-old girl with first degree heart block and two ventricular septal defects, a mesothelioma of the atrioventricular node was noted upon histologic examination of the conduction system. Predominant in the female sex, the condition may occur at any age, 16 of the reported cases being under 30 years of age.

Mapping the Atrioventricular Node

New England Journal of Medicine, 2007
A 75-year-old woman presented with dyspnea, an awareness of rapid heart action, and permanent atrial fibrillation with a rapid ventricular response that had been resistant to treatment with beta-blockers, calcium-channel blockers, digoxin, and multiple cardioversions. For severe rheumatic aortic and mitral stenosis, she had undergone replacement of the

Arterial vascularisation of the atrioventricular node

Surgical and Radiologic Anatomy, 2000
The aim of this study was to define the anatomic characteristics of the principal arterial source of the atrioventricular node, known as the artery of the atrioventricular node. Forty hearts were studied by various anatomic and radiologic methods: dissection, injection-dissection, injection-corrosion and injection-radiography, but only 23 results were ...

Connexins in the Sinoatrial and Atrioventricular Nodes

2006
The sinoatrial node (SAN) and the atrioventricular node (AVN) are specialized tissues in the heart: the SAN is specialized for pacemaking (it is the pacemaker of the heart), whereas the AVN is specialized for slow conduction of the action potential (to introduce a delay between atrial and ventricular activation during the cardiac cycle).

Reconstruction of the human atrioventricular node

The Anatomical Record, 1967
AbstractThe right atrioventricular junction and A‐V node area in each of five human hearts was studied histologically in serial sections. The A‐V node of a 54‐year old female was reconstructed in four colors to provide a three‐dimensional model of cardiac relationships, blood supply, and nodal configuration.

Mesothelioma (Coelothelioma) of the Atrioventricular Node

Chest, 1971
This is the 12th reported case of benign mesothelioma of the atrioventricular (AV) node, studied both clinically and pathologically. In this case, serial sections were done throughout the entire conduction system. The patient clinically showed AV block with a nodal pacemaker.

Electrical activity in sinus node and atrioventricular node

American Heart Journal, 1956
Summary Complicated multiphasic differential complexes of a low voltage are demonstrated locally in the anatomic sinus nodal region. This local sinus activity is, in differential leads, most characteristic in that part of the sinus node, where, in simultaneous unipolar leads, the initial negativity is found. Pure initial negativity is seen only in a
