Reduction of Fluoroscopy Exposure During Atrial Fibrillation Ablation

Status Completed

Clinical Trial Summary

To evaluate reduction of fluoroscopy time/dosis and safety of atrial fibrillation ablation in patients with paroxysmal atrial fibrillation using fluoroscopy image integrated 3-dimentional electroanatomical mapping system, comparing to using 3-dimentional electroanatomical mapping system without fluoroscopy image integration

Clinical Trial Description

The novel fluoroscopic image integrated 3-dimentional electroanatomical mapping system is designed for minimizing the exposure to X-ray for physician, staff and patients. This randomized single-center study is to evaluate the reduction on fluoroscopy levels (time and dosis) in catheter interventional treatment of symptomatic, antiarrhythmic refractory paroxysmal atrial fibrillation using fluoroscopic image integrated 3-dimentional electroanatomical mapping system, comparing with using 3-dimentional electroanatomical mapping system without fluoroscopic image integration. Patients with documented paroxysmal atrial fibrillation, who are going to receive a catheter interventional treatment to atrial fibrillation, will be randomized (1:1) into two groups after signing an informed consent. Group 1 (CARTOUNIVU): using fluoroscopic image integrated 3-dimentional electroanatomical mapping system. Group 2 (CARTO3): using 3-dimentional electroanatomical mapping system without fluoroscopic image integration.

The ablation strategies in both study groups are the same, including circumferential isolation of ipsilateral pulmonary veins (PV) and voltage map guided substrate modification. According to the randomization, the ablation procedure will be performed with or without fluoroscopic image integration.

The primary endpoint of this study is the evaluation of reduction on fluoroscopy levels (fluoroscopy time and dosis) during atrial fibrillation ablation procedure. Secondary endpoints include complete isolation of the pulmonary veins, completely bidirectional block of linear ablation lines, total procedure time, ablation-related complications. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
