This study is intended to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach with conventional fluoroscopic approach as performing catheter ablation of right atrial arrhythmias.
Catheter ablation is a well-established treatment to treat patients with a wide range of heart rhythm disturbances. Fluoroscopy is the imaging modality routinely used for cardiac device implantation and electrophysiological procedures. Due to the rising concern regarding the harmful effects of radiation exposure to both the patients and operation staffs, novel three-dimensional mapping systems such as Ensite NavX have been developed and implemented in electrophysiological procedure for the navigation of catheters inside the heart chambers. Ensite NavX is a promising system to guide catheters inside the cardiac chambers and vessels without the use of fluoroscopy. This study is intended to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach with conventional fluoroscopic approach as performing catheter ablation of right atrial arrhythmias.
