Idiopathic Ventricular Arrhythmia Ablation Using Non-Fluoroscopic Catheter Visualization System

Catheter ablation of symptomatic idiopathic ventricular arrhythmias

Aims This study was designed to gain insight into the patient characteristics, results and possible complications of ablation procedures for symptomatic idiopathic premature ventricular complexes (PVC) and idiopathic ventricular tachycardia (VT). Methods Data were collected from all patients who underwent radiofrequency catheter ablation for symptomatic PVCs and idiopathic VT in the Catharina H...

Catheter ablation of idiopathic right ventricular tachycardia.

C atheter ablation of ventricular tachycardia has become an alternative to pharmacological, electrical, or surgical therapy of severe ventricular tachyarrhythmias. It may be successful in about two thirds of patients with ventricular tachycardia of various origins.1-7 Though catheter ablation of ventricular tachycardia is still an evolving, and thus experimental, technique, it has proven indisp...

Catheter ablation of idiopathic ventricular tachycardia.

Idiopathic ventricular arrhythmias can originate from either the endocardial, midmyocardial, or epicardial regions of the heart. The outflow tracts and basal regions of the ventricle tend to be common locations of origin of these tachycardias. The anatomy of this region of the heart is both fascinating and, at times, challenging from a procedural standpoint. The orientation of the outflow tract...

Epicardial access and ventricular tachycardia ablation in a postmyocarditis patient using a nonfluoroscopic catheter visualization system

Introduction The efficacy of catheter ablation for scar-related ventricular tachycardia (VT) has significantly improved since the introduction of percutaneous epicardial access by Sosa in 1996. Percutaneous epicardial ablation has been used in approximately 30% of VT ablation cases associated with nonischemic cardiomyopathy. However, complications such as cardiac tamponade, coronary artery lace...
