Nonfluoroscopic Catheter Ablation. Results From a Prospective Multicenter Registry

Area of Science:

• Cardiology
• Electrophysiology
• Medical Imaging

Background:

• Nonfluoroscopic catheter ablation aims to reduce radiation exposure.
• Assessing the safety and feasibility of zero-fluoroscopy is crucial for widespread adoption.

Purpose of the Study:

• To evaluate the safety and feasibility of a zero-fluoroscopic approach for catheter ablation in Spain.
• To identify factors influencing the need for fluoroscopy during these procedures.

Main Methods:

• A prospective, multicenter registry including 247 patients undergoing catheter ablation.
• Exclusion of patients with intracardiac devices; focus on operators deeming procedures suitable for zero-fluoroscopy.
• Data collected on fluoroscopy use, procedural success, and complications.

Main Results:

• Catheter ablation was performed in 95.2% of patients, with 96.4% success rate.
• Fluoroscopy was used in 10.3% of procedures, primarily for right-sided arrhythmias.
• Severe complications occurred in 0.85% of patients; need for fluoroscopy linked to procedural failure and center.

Conclusions:

• A zero-fluoroscopic approach is feasible for the majority of right-sided catheter ablations.
• Randomized trials are recommended to confirm the safety of this approach.
• Procedural failure and institutional factors influenced fluoroscopy use.
