Successful Prevention of Fetal Autoimmune-Mediated Heart Block by Combined Therapies With Hydroxychloroquine and Intravenous Immunoglobulin: A Case Report

Frontiers in Cardiovascular Medicine, 2021
A fetal autoimmune-mediated atrioventricular block is a passively acquired autoimmune disease in which maternal autoantibodies enter the fetal circulation via the placenta and subsequently cause inflammation and fibrosis of the atrioventricular node ...

Coronary Sinus Activation Pattern in Patients with Atrioventricular Nodal Reentrant Tachycardia

Journal of Arrhythmia, 2007
Patterns of left atrial (far-field signals) or coronary sinus (CS) muscle (near-field) have been defined in CS recordings. The purpose of this study was to define the activation patterns from the coronary sinus in patients with anterior and posterior ...

Cystic Tumor of the Atrioventricular Node Causing Rapid-Onset and Reversible Complete Heart Block

JACC: Case Reports, 2023
Cystic tumors of the atrioventricular node are rare primary cardiac neoplasms, frequently reported as a postmortem diagnosis during autopsy. Despite their small size, they can present with complete heart block or sudden cardiac death.

Ultrastructure of the mesothelioma of the atrioventricular node [PDF]

Cancer, 1977
In order to determine the histogenesis of tumors of the atrioventricular node, so-called conduction tumors, two such tumors were serially blocked for electron microscopy. Ultrastructurally these tumors were composed of nests of cells arranged in small channels and tubules set in a connective tissue stroma. The cells lining the tubules were flattened or

The Role of Electrophysiologic Study in Device Selection for Leadless Atrial Pacing [PDF]

Texas Heart Institute Journal
The AVEIR DR (Abbott Medical) was the first dual-chamber leadless pacing system approved by the US Food and Drug Administration. Many patients with sinus node dysfunction have physiologically normal atrioventricular conduction, so an atrial-only pacing ...

Cystic tumour of the atrioventricular node [PDF]

Heart, 2003
A 45 year old asymptomatic woman was referred to our clinic because of first degree atrioventricular block on ECG. Transthoracic echocardiography revealed a well delineated mass (27 mm × 29 mm) without …

Trimethoprim/Sulfamethoxazole-Induced Bradycardia, Renal Failure, AV-Node Blockers, Shock and Hyperkalemia Syndrome

Clinical Practice and Cases in Emergency Medicine, 2019
BRASH (bradycardia, renal failure, atrioventricular-node blockers, shock, and hyperkalemia) syndrome is a recently coined term for a condition that describes the severe bradycardia and shock associated with hyperkalemia in patients on atrioventricular ...

Atrioventricular Node Ablation to Enhance Resynchronization Therapy Response in a Patient With Complete Atrioventricular Block

JACC: Case Reports, 2021
Up to one-third of patients who undergo cardiac resynchronization therapy do not obtain clinical benefit. A systematic approach can identify treatable causes in many nonresponding patients.

Ultrastructure of the Human Atrioventricular Node [PDF]

Circulation, 1968
Ultrastructure of the A-V node was studied in two human hearts. Fine details of intranodal cellular organization were then resynthesized on the basis of light microscopic examinations of over 250 human hearts. There are four different types of cells and no anatomic syncytium in the human A-V node: (1) a simple rounded cell identical to P cells of the ...
