Zero X-ray catheter ablation using non-fluoroscopic mapping is safe and effective for treating tachyarrhythmias. This approach offers excellent long-term outcomes and reduces risks for patients and physicians.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Technology

Background:

  • Conventional radiofrequency catheter ablation (RFCA) for tachyarrhythmias involves radiation exposure, posing risks to patients and operators.
  • Advancements in non-fluoroscopic mapping systems allow for catheter ablation with minimal or zero fluoroscopy.

Purpose of the Study:

  • To evaluate the long-term outcomes of "Zero X-ray" catheter ablation for tachyarrhythmias.
  • To assess the very long-term benefits of eliminating fluoroscopy in catheter ablation procedures.

Main Methods:

  • A "Zero X-ray" approach using non-conventional mapping systems (EnSite NavX™, Ensite™ Velocity™, Ensite™ Precision™) was employed.
  • A total of 272 arrhythmias in 266 patients were treated without any fluoroscopic guidance.

Main Results:

  • 100% acute success rate with a 0.8% complication rate.
  • 90.8% chronic success rate over an average follow-up of 2.9 years.
  • Recurrence occurred in some patients, managed by repeat ablation or medication.

Conclusions:

  • Non-fluoroscopic catheter ablation is a safe and feasible alternative to traditional fluoroscopy for treating arrhythmias.
  • This method achieves high acute success rates, low complication rates, and comparable long-term outcomes.
  • Eliminating fluoroscopy during catheter ablation provides clinical benefits without compromising patient safety.
