Direct Epicardial Mapping and Ablation Revealing Three‐Dimensional Roof‐Dependent Macroreentrant Atrial Tachycardia Breaking Into Bachmann's Bundle [PDF]

Clinical Case Reports
Catheter ablation for macroreentrant atrial tachycardia (AT) that recurs after atrial fibrillation (AF) ablation is occasionally difficult because of epicardial connections.

Unusual Complications of Percutaneous Epicardial Access and Epicardial Mapping and Ablation of Cardiac Arrhythmias [PDF]

Circulation: Arrhythmia and Electrophysiology, 2011
Background— Percutaneous epicardial access and mapping/ablation of cardiac arrhythmias are being increasingly performed. Although complications such as pericardial effusion are relatively common, other unusual complications may occur due to the complex anatomic architecture of the heart and surrounding tissues.

Techniques for epicardial mapping and ablation with a miniature robotic walker. [PDF]

Robot Surg, 2017
Present treatments for ventricular tachycardia have significant drawbacks. To ameliorate these drawbacks, it may be advantageous to employ an epicardial robotic walker that performs mapping and ablation with precise control of needle insertion depth.

Unipolar atrial electrogram morphology is affected by age: evidence from high-resolution epicardial mapping [PDF]

Annals of Medicine, 2023
Background It is unknown which features of unipolar atrial electrogram (U-AEGM) morphology are affected by ageing and whether age-related changes in U-AEGM morphology are equally distributed throughout the right and left atria.Patients and methods ...

Effect of Epicardial Fat on Electroanatomical Mapping and Epicardial Catheter Ablation

Journal of the American College of Cardiology, 2010
The purpose of this study was to correlate 3-dimensional distribution of epicardial fat on computed tomography (CT) with electroanatomical (EA) voltage maps obtained during percutaneous epicardial mapping in order to determine the fat thickness cut-off that results in voltage attenuation and to establish normal ventricular epicardial voltage criteria ...

Electromechanical and structural phenotypes from cardiac imaging and epicardial mapping in inherited arrhythmia syndromes [PDF]

Frontiers in Cardiovascular Medicine
Inherited arrhythmia syndromes—including Brugada syndrome (BrS), long QT syndrome (LQTS), catecholaminergic polymorphic ventricular tachycardia (CPVT), and short QT syndrome (SQTS)—can cause malignant arrhythmias and sudden cardiac death without overt ...

Entrance‐Site Ablation in Atrial Tachycardia Involving Epicardial Conduction: A Case Series [PDF]

Journal of Arrhythmia
Background Treatment of atrial tachycardia (AT) involving epicardial conduction remains challenging. While endocardial exit sites can serve as targets for radiofrequency (RF) ablation, this approach is sometimes ineffective and may result in treatment ...

Right ventricular outflow tract endocardial unipolar substrate mapping: implications in risk stratification of Brugada syndrome [PDF]

Reviews in Cardiovascular Medicine, 2022
Brugada syndrome (BrS) is a complex arrhythmogenic disease displaying electrical and micro-structural abnormalities mainly located at the epicardium of the right ventricular outflow tract (RVOT).

Electrophysiological mapping of the epicardium via 3D‐printed flexible arrays

Bioengineering & Translational Medicine, 2023
Cardiac electrophysiology mapping and ablation are widely used to treat heart rhythm disorders such as atrial fibrillation (AF) and ventricular tachycardia (VT). Here, we describe an approach for rapid production of three dimensional (3D)‐printed mapping

Wt1 and Epicardial Fate Mapping [PDF]

Circulation Research, 2012
Rationale: The embryonic epicardium is a crucial cell source of the cardiac fibrous skeleton as well as of the coronary system. Genetic lineage tracing systems based on Wt1 regulatory sequences provided evidence that epicardium-derived cells also adopt a ...
