Epicardial high-resolution mapping of advanced interatrial block: Relating ECG, conduction abnormalities and excitation patterns

Frontiers in Cardiovascular Medicine, 2023
BackgroundImpairment of conduction across Bachmann’s Bundle (BB) may cause advanced interatrial block (a-IAB), which in turn is associated with development of atrial fibrillation.

Human epicardial adipose tissue expresses a pathogenic profile of adipocytokines in patients with cardiovascular disease [PDF]

, 2006
Introduction: Inflammation contributes to cardiovascular disease and is exacerbated with increased adiposity, particularly omental adiposity; however, the role of epicardial fat is poorly understood.

Comparing Non-invasive Inverse Electrocardiography With Invasive Endocardial and Epicardial Electroanatomical Mapping During Sinus Rhythm

Frontiers in Physiology, 2021
This study presents a novel non-invasive equivalent dipole layer (EDL) based inverse electrocardiography (iECG) technique which estimates both endocardial and epicardial ventricular activation sequences.

Transmural “Scar-to-Scar” Reentrant Ventricular Tachycardia

Indian Pacing and Electrophysiology Journal, 2013
We describe a scar-related reentrant ventricular tachycardia circuit with a proximal segment in an endocardial basal septal scar and an exit in a region of slow conduction in a non-overlapping region of epicardial basal lateral scar.

Epicardial and Endocardial Ablation Based on Channel Mapping in Patients With Ventricular Tachycardia and Chronic Chagasic Cardiomyopathy: Importance of Late Potential Mapping During Sinus Rhythm to Recognize the Critical Substrate

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Ventricular tachycardia (VT) in patients with chronic chagasic cardiomyopathy (CCC) is associated with considerable morbidity and mortality. Catheter ablation of VT in patients with CCC is very complex and challenging.

The three-dimensional substrate of atrial fibrillation in the goat : a simultaneous endo-epicardial mapping study [PDF]

, 2012
Atrial fibrillation (AF) is the most common arrhythmia in humans and Maastricht is a reference center for mapping of AF. Mapping is a technique to visualize the electrical activity of the atrial muscle. In earlier studies this was performed solely on the

Non-invasive topical diagnostics of heart arrhythmias

Патология кровообращения и кардиохирургия, 2015
The aim of this study was to measure the accuracy of noninvasively obtained ventricular activation (isolated epicardial vs combined endo-epicardial mapping) as compared with that of standard invasive mapping in patients with ventricular arrhythmias.

Robotic Hybrid Ablation with Novel Epicardial Electrophysiological Mapping: Impact on Atrial Fibrillation Therapy [PDF]

We report the first use of the EnSite X system for intraoperative electrophysiological mapping during a robotic hybrid ablation (ROK-AF procedure) for long-standing persistent atrial fibrillation.

Epicardial mapping and ablation of biatrial macroreentrant tachycardia via Bachmann's bundle

, 2023
Introduction: Recent reports highlighted the role of epicardial connections in the development of biatrial tachycardia circuits. Methods: We reported a case of 60-year-old female patient who was admitted with recurrent atrial tachycardia (AT) after ...

Open surgical ablation of ventricular tachycardia: Utility and feasibility of contemporary mapping and ablation tools

Heart Rhythm O2, 2021
Background: Ventricular tachycardia (VT) catheter ablation success may be limited when transcutaneous epicardial access is contraindicated. Surgical ablation (SurgAbl) is an option, but ablation guidance is limited without simultaneously acquired ...
