Summary
A novel 3D-guided workflow for atrioventricular nodal re-entrant tachycardia (AVNRT) ablation is safe and effective. This standardized approach achieved 100% acute success with no heart block, eliminating fluoroscopy use.
Area of Science:
- Electrophysiology
- Cardiac Ablation
Background:
- Atrioventricular nodal re-entrant tachycardia (AVNRT) ablation is effective but risks heart block.
- A standardized, 3D-guided workflow for AVNRT ablation is needed.
Purpose of the Study:
- To define a standardized, safety-driven, 3D-guided workflow for AVNRT ablation.
- To evaluate the feasibility and outcomes of this approach in a day-hospital setting.
Main Methods:
- Retrospective analysis of 150 AVNRT patients undergoing ablation (2017-2025).
- Utilized the PICENO AVNRT approach integrating Koch's triangle pace mapping and voltage-bridge mapping.
- Standardized 3D-guided, safety-driven workflow without fluoroscopy.
Main Results:
- 100% acute procedural success.
- Zero cases of transient or permanent atrioventricular block.
- 0.7% recurrence rate at 30.5 months follow-up.
- Mean procedure time: 62 ± 14 minutes.
Conclusions:
- A standardized 3D-guided workflow for AVNRT ablation is feasible and reproducible.
- This safety-driven approach achieves excellent outcomes in a day-hospital setting.
- Elimination of fluoroscopy is possible due to procedural reliability.
