Coexistence of a Classical Nodoventricular Accessory Pathway With a Left-Sided Mahaim Accessory Pathway [PDF]

JACC: Case Reports
The coexistence of 2 Mahaim pathways represents a diagnostic challenge. We present a case in which the SH/HA intervals were useful for identifying concealed nodoventricular or His-ventricular pathways.

Parasystole in a Mahaim Accessory Pathway [PDF]

Indian Pacing and Electrophysiology Journal, 2014
Automaticity has been described in Mahaim pathways, both spontaneously and during radiofrequency ablation. We describe an unusual case of automatic rhythm from a Mahaim pathway presenting as parasystole. The parasystolic beats were also found to initiate

Case Report: Pulsed field ablation for epicardial right-sided accessory pathway [PDF]

Frontiers in Cardiovascular Medicine
We present a case of a 32-year-old male with a history of palpitations and preexcitation on ECG who underwent altogether four failed catheter ablations using different approaches in the two other electrophysiology centers within two years.

Landiolol, an intravenous β1‐selective blocker, is useful for dissociating a fusion of atrial activation via accessory pathway and atrioventricular node [PDF]

Journal of Arrhythmia, 2023
Introduction During ventricular pacing, a fusion of atrial activation may occur owing to the simultaneous retrograde conduction of the atrioventricular (AV) node and accessory pathway (AP), potentially leading to an inaccurate mapping of the atrial AP ...

Total activation mapping in a patient with an epicardial accessory pathway [PDF]

Annals of Noninvasive Electrocardiology, 2022
A 42‐year‐old man was admitted for recurrent atrioventricular reciprocating tachycardia. We performed a total activation mapping, which included a range from the ventricular to atrial waves during right ventricular pacing.

Clinical characteristics and electrophysiologic properties of atrioventricular accessory pathways: Importance of the accessory pathway location

Journal of the American College of Cardiology, 1992
This study was designed to assess the influence of accessory atrioventricular (AV) pathway location on the clinical and electrophysiologic characteristics of 384 consecutive symptomatic patients having a single accessory pathway.Four locations were studied: left free wall (n = 270), posteroseptal (n = 52), anteroseptal (n = 29) and right free wall (n =

Open window mapping for redo accessory pathway ablation in Ebstein anomaly [PDF]

Indian Pacing and Electrophysiology Journal
Accessory pathway ablation in Ebstein anomaly can be significantly more challenging than in structurally normal hearts. An alternative to the conventional approach to mapping APs is to detect points with a high-density mapping catheter based on an ...

Use of 3D mapping system for ablating an accessory pathway associated with coronary sinus diverticulum

International Journal of Arrhythmia, 2021
Background This is a rare and challenging case of Wolff–Parkinson–White syndrome due to a posteroseptal accessory pathway located in the coronary sinus diverticulum.
