Electro-anatomical mapping of the left atrium before and after cryothermal balloon isolation of the pulmonary veins [PDF]

, 2009
Introduction: The 28 mm cryoballoon catheter is a device used for pulmonary vein isolation (PVI). The aim of this study was to evaluate the extent of the ablation in the antral regions of the left atrium.

Responsiveness to bepridil predicts atrial substrate in patients with persistent atrial fibrillation

Journal of Arrhythmia, 2021
Background The low voltage zone (LVZ) detected with three‐dimensional electroanatomical mapping is a surrogate marker of atrial scar in patients with persistent atrial fibrillation (PeAF) and is associated with poor clinical outcomes after catheter ...

Autoimmune Myocarditis and Arrhythmogenic Mitral Valve Prolapse: An Unexpected Overlap Syndrome

Journal of Cardiovascular Development and Disease, 2021
Background: both myocarditis and mitral valve prolapse (MVP) are known uncommon causes of ventricular arrhythmias in young patients. Aim: to report the first clinical case of endomyocardial biopsy (EMB)-proven autoimmune myocarditis and associated ...

Ripple mapping: Making electroanatomic mapping user-friendly [PDF]

Heart Rhythm, 2009
With the introduction of electroanatomic mapping systems, electrical voltage maps of the chamber of interest and activation maps of arrhythmias have emerged as invaluable tools for successful ablation of focal and reentrant arrhythmias.(1) In reentrant rhythms that cause hemodynamic instability, substrate modification has been demonstrated to achieve ...

Impact of corticosteroids on late growth of radiofrequency lesions in infant pigs: histopathological and electroanatomical findings [PDF]

, 2011
Aims Corticosteroids attenuate late growth of radiofrequency (RF) lesions in the thigh muscle of infant rats. We sought to assess the impact of these drugs on the late growth of RF lesions in immature swine myocardium and to determine the ...

Three-dimensional electroanatomical mapping for non-pulmonary vein foci in a patient with complete situs inversus and dextrocardia

Indian Pacing and Electrophysiology Journal, 2018
In patients with atrial fibrillation (AF) having congenital anatomical abnormalities, such as complete situs inversus and dextrocardia, pulmonary vein isolation (PVI) ablation can be performed safety using a three-dimensional electroanatomical mapping ...

Advanced ablation strategies for management of post-surgical atrial arrhythmias. [PDF]

, 2013
Post-surgical arrhythmias include a wide range of arrhythmias occurring late after cardiac surgery and represent a complex substrate for catheter ablation either because of extended scar and remodeling or because of limited access to the area of interest.

A Case Study on Cardiac Imaging in Patients with Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy —A Comparison between 64-Slice Computed Tomography, Magnetic Resonance Imaging and Electroanatomical Mapping—

Journal of Arrhythmia, 2007
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an uncommon type of cardiomyopathy with fibrofatty tissue replacement. Magnetic resonance imaging (MRI) is a sophisticated method for the diagnosis of ARVD/C. Electroanatomical mapping

Impact of respiration gating on image integration guided atrial fibrillation ablation [PDF]

, 2014
BACKGROUND: Radiofrequency (RF) catheter ablation guided by electroanatomic mapping systems is an effective therapy for atrial fibrillation. However, it may be affected by respiration movements.

Three-dimensional electroanatomical mapping for atrioventricular nodal reentrant tachycardia associated with persistent left superior vena cava

Journal of Arrhythmia, 2013
Background: The anatomical courses of the slow pathway and His bundle are altered in patients with atrioventricular nodal reentrant tachycardia (AVNRT) associated with persistent left superior vena cava (PLSVC).
