Zero-fluoroscopic Ablation Versus Conventional Fluoroscopic Ablation for the Treatment of Ventricular Arrhythmias
Zero-fluoroscopic Ablation Versus Conventional Fluoroscopic Ablation for the Treatment of Ventricular Arrhythmias
This study is intended to compare the feasibility, safety and efficacy of a zero-fluoroscopy
 approach using Ensite NavX as the only imaging modality with conventional fluoroscopic
 approach for the catheter ablation of idiopathic ventricular arrhythmias; conventional
 fluoroscopic approach use fluoroscopy plus Ensite NavX or plus Carto as the imaging modality.
Catheter ablation is a well-established treatment to treat patients with a wide range of
 heart rhythm disturbances. Fluoroscopy is a imaging modality routinely used for the ablation
 of arrhythmias.Due to the rising concern regarding the harmful effects of radiation exposure
 to both the patients and operation staffs; three-dimensional mapping systems, including CARTO
 and Ensite NavX, have been developed and implemented in electrophysiological procedure for
 the navigation of catheters inside the heart chambers. Ensite NavX system can be used for
 zero-fluoroscopy approach for catheter ablation of arrhythmias. This study is intended to
 compare the feasibility, safety and efficacy of a zero-fluoroscopy approach using Ensite NavX
 as the only imaging modality with conventional fluoroscopic approach for the catheter
 ablation of idiopathic ventricular arrhythmias; conventional fluoroscopic approach use
 fluoroscopy plus Ensite NavX or plus Carto as the imaging modality.
