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

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).

Electrophysiological Features of Atrial Flutter in Cardiac Sarcoidosis: A Report of Two Cases

Indian Pacing and Electrophysiology Journal, 2012
We report two cases of systemic sarcoidosis with atrial flutter as the clinical manifestation. In one patient, who had symptoms of shorter duration, the arrhythmia was no longer inducible after a course of glucocorticoid therapy.

Efficacy of Electroanatomical Mapping for Radiofrequency Ablation of Right-sided Accessory Pathways

Journal of Arrhythmia, 2005
Introduction: Due to the difficulty in performing detailed mapping around the tricuspid annulus and the high occurrence of mechanical trauma during the procedure, the outcome of right-sided accessory pathway (AP) ablation still has a relatively high ...

3D electroanatomical mapping is less sensitive to atrial remodeling in estimation of true left atrial volume than echocardiography

BMC Medical Imaging, 2018
Background Left atrial (LA) enlargement has been identified as a predictor of worse clinical outcome after catheter ablation for atrial fibrillation (AF).

Atrial tachycardia in a patient with arrhythmogenic right ventricular cardiomyopathy/dysplasia

Journal of Arrhythmia, 2013
We describe a 49-year-old woman with atrial tachycardia (AT) and arrhythmogenic right ventricular cardiomyopathy/dysplasia. Cardiac magnetic resonance images showed a markedly dilated right atrium and right ventricle.

Catheter ablation of three macroreentrant atrial tachycardias after surgical repair of Double-Outlet Right Ventricle

Journal of Arrhythmia, 2012
A 54-year-old man with a surgically repaired double-outlet right ventricle (DORV) presented with palpitations and worsening right heart failure. His 12-lead ECG showed atrial tachycardia (AT) with an atrial cycle length (CL) of 300 ms and an inverted saw-

Prediction of Type and Recurrence of Atrial Fibrillation after Catheter Ablation via Left Atrial Electroanatomical Voltage Mapping Registration and Multilayer Perceptron Classification: A Retrospective Study

Sensors, 2022
Atrial fibrillation (AF) is a common cardiac arrhythmia and affects one to two percent of the population. In this work, we leverage the three-dimensional atrial endocardial unipolar/bipolar voltage map to predict the AF type and recurrence of AF in 1 ...

Noninvasive 3D Mapping and Ablation of Epicardial Premature Ventricular Contractions From the Endocardial Aspect of the Left Atrial Appendage

JACC: Case Reports, 2020
Ablation is an established treatment for ectopy originating from the left ventricle (LV). We report on a case of noninvasive 3-dimensional mapping locating the origin precisely in the epicardial LV summit area.

Contemporary Management of Complex Ventricular Arrhythmias

Arrhythmia & Electrophysiology Review, 2022
Percutaneous catheter ablation is an effective and safe therapy that can eliminate ventricular tachycardia, reducing the risks of both recurrent arrhythmia and shock therapies from a defibrillator.
