Optimal method for ablation of atypical AVNRT

BMC Cardiovascular Disorders, 2023
Background Considering that ablation of atypical AVNRT may be unsuccessful after ablation at the right posterior septum, in this study, we aimed to present an optimal method for ablation of atypical AVNRT.

Introduction of Low‐Voltage Bridge Mapping for Radiofrequency Ablation of AVNRT in Children: One‐Year Follow‐Up Results [PDF]

Journal of Arrhythmia
Background Low‐voltage bridge mapping (LVBM) is a recently introduced approach to atrioventricular nodal reentry tachycardia (AVNRT) ablation that may facilitate precise slow‐pathway targeting.

Recurrent A V block following ablation for AVNRT [PDF]

Indian Heart Journal, 2014
Slow pathway modification has become the mainstay for the treatment of atrio-ventricular nodal re-entrant tachycardia (AVNRT) ablation because of high success rate and low incidence of complications. Our patient had a rare complication of slow pathway modification by radiofrequency ablation (RFA) in form of delayed complete heart block, occurring 10 ...

Integrative Analyses Identify Potential Key Genes and Calcium-Signaling Pathway in Familial Atrioventricular Nodal Reentrant Tachycardia Using Whole-Exome Sequencing [PDF]

Frontiers in Cardiovascular Medicine, 2022
BackgroundAtrioventricular nodal reentrant tachycardia (AVNRT) is a common arrhythmia. Growing evidence suggests that family aggregation and genetic factors are involved in AVNRT.

Coronary sinus ostium anatomy in patients with atrioventricular nodal and atrioventricular reentrant tachycardia: a cardiac computed tomography study [PDF]

BMC Cardiovascular Disorders
Background The coronary sinus (CS) is anatomically related to the atrioventricular node and the slow pathway region and may influence the mechanisms of supraventricular tachycardia.

Simultaneous dual AV node antegrade conduction (2 for 1) and lower common pathway (2–1) block illustrate AVNRT physiology

Indian Pacing and Electrophysiology Journal, 2020
We report a rare case of spontaneous initiation of Atrioventricular nodal reentry tachycardia (AVNRT) via 2 for 1 phenomenon, into a 2:1 AV block due to lower common pathway block and finally transition to 1:1 tachycardia.

Prevalence and Structured Approach to the Diagnoses of A on V Tachycardias [PDF]

Journal of Arrhythmia
Background “A on V” tachycardia (AoV‐T) is classically considered suggestive of atrioventricular nodal reentrant tachycardia (AVNRT); emerging evidence suggests that other mechanisms may present with this electrogram pattern.

Classification of AVNRT: an unresolved entity. [PDF]

Journal of Cardiovascular Electrophysiology, 2021
The classification of AVNRT is based on HA and VA interval. Typical AVNRT is diagnosed in presence of HA ≤70 ms OR VA interval ≤60 ms and HA>70ms or VA >60ms is required to diagnose atypical AVNRT. This might be fallacious in some clinical situations. The septal VA and the “shortest” VA may be also different depending on clinical scenario .

Association Between the Coronary Sinus Ostial Size and Atrioventricular Nodal Reentrant Tachycardia in Patients With Pulmonary Arterial Hypertension

Frontiers in Physiology, 2022
AimsThe incidence of atrioventricular nodal reentrant tachycardia (AVNRT) is higher in pulmonary arterial hypertension (PAH) patients than in the general population. AVNRT is reportedly associated with a larger coronary sinus (CS) ostium (CSo).

Change in VA interval by a single atrial premature depolarization - What is the mechanism?

Indian Pacing and Electrophysiology Journal, 2022
A long VA tachycardia during a typical atrioventricular nodal reentrant tachycardia (AVNRT) can be a concomitant atypical AVNRT, atrial tachycardia or rarely atrio-ventricular reentrant tachycardia (AVRT).
