Zero-Fluoroscopy Versus Conventional Catheter Ablation for Premature Ventricular Contractions

Area of Science:

• Cardiology
• Electrophysiology
• Medical Technology

Background:

• Catheter ablation is a primary treatment for premature ventricular contractions (PVCs).
• Traditional fluoroscopy-guided ablation poses radiation risks, particularly for young patients or those needing repeat procedures.
• Zero-fluoroscopy (ZF) techniques offer a radiation-free alternative.

Purpose of the Study:

• To compare the safety and efficacy of ZF PVC ablation versus conventional fluoroscopy (CF).
• To evaluate procedural outcomes, including success rates, procedure time, and complications.

Main Methods:

• A retrospective, single-center study of 150 patients undergoing PVC ablation.
• Patients were divided into two groups: ZF (n=75) and CF (n=75).
• Comparison of procedural characteristics, time, success rates, and complications.

Main Results:

• Overall acute procedural success was 79.3%, with comparable rates between ZF (78.7%) and CF (80.0%) groups.
• Median procedure times were similar (88 min vs. 90 min), as were complication rates (4.0% vs. 4.0%).
• ZF ablation demonstrated longer procedure times for complex PVC origins (LV-superior, summit) but comparable outcomes; RV-inferior PVCs had high success and short duration.

Conclusions:

• Zero-fluoroscopy PVC ablation is a safe and effective alternative to conventional fluoroscopy.
• The ZF approach eliminates radiation exposure without compromising procedural success or safety.
• While complex cases may require longer procedure times, ZF offers a valuable radiation-sparing option.
