Clinical Trial Summary

This study is aimed to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach using Ensite NavX with conventional fluoroscopic approach using Ensite NavX plus fluoroscopy for the ablation of paroxysmal supraventricular tachycardia.

Description:

Fluoroscopy is the imagine modality routinely used in catheter ablation of cardiac arrhythmias. As we all know,fluoroscopic radiation is harmful both to the patients and the operation staffs. Recently,three-dimensional navigation systems have been developed and implemented in electrophysiological procedures for guiding catheters inside the heart chambers. Among the three-dimensional navigation systems, Ensite NavX is a promising system used for zero-fluoroscopic approach for performing catheter ablation of paroxysmal supraventricular tachycardia. This study is aimed to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach using Ensite NavX with conventional fluoroscopic approach using Ensite NavX plus fluoroscopy for the ablation of paroxysmal supraventricular tachycardia.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Procedural success rate	Procedural success for AVNRT was defined as the absence of inducible tachycardia either under basal condition or under isoproterenol stimulation. Procedural success for AVRT was defined as the non-inducibility of tachycardia, loss of pre-excitation (if manifest), loss of retrograde accessory pathway conduction and transient atrioventricular block induced by intravenous adenosine.	one year
Secondary	Complications	Complications were defined as pseudoaneurysm, arterialvenous fistula, pneumothorax, second- or third-degree atrioventricular block, cardiac tamponade, or other serious complications requiring intervention.	one year
Secondary	Immediate success rate	Procedural success for AVNRT was defined as the absence of inducible tachycardia either under basal condition or under isoproterenol stimulation. Procedural success for AVRT was defined as the non-inducibility of tachycardia, loss of pre-excitation (if manifest), loss of retrograde accessory pathway conduction and transient atrioventricular block induced by intravenous adenosine.	one day
Secondary	Recurrence Rate	2. An ECG and electrophysiology study would be performed to rule out recurrence when the patients had suspicious symptoms or signs.	1 year
Secondary	Total procedure time	Procedure time (in minutes) was defined as the interval from the beginning of local anesthesia to extraction of all femoral venous sheaths at the end of the procedure. Total ablation time was calculated in seconds but time for tentative ablation was not taken into account.	one day
Secondary	Fluoroscopy time	2. Fluoroscopy time (in minutes) was defined as thetotal duration of exposure during the procedure.	one day
