Abstract
Background
High-frequency low-tidal-volume (HFLTV) ventilation is a safe and cost-effective strategy that improves catheter stability, first-pass pulmonary vein isolation, and freedom from all-atrial arrhythmias during radiofrequency catheter ablation (RFCA) of paroxysmal and persistent atrial fibrillation (AF). However, the incremental value of adding rapid-atrial pacing (RAP) to HFLTV-ventilation has not yet been determined.
Objective
To evaluate the effect of HFLTV-ventilation plus RAP during RFCA of paroxysmal AF on procedural and long-term clinical outcomes compared to HFLTV-ventilation alone.
Methods
Patients from the REAL-AF prospective multicenter registry, who underwent RFCA of paroxysmal AF using either HFLTV + RAP (500–600 msec) or HFLTV ventilation alone from April 2020 to February 2023 were included. The primary outcome was freedom from all-atrial arrhythmias at 12-month follow-up. Secondary outcomes included procedural characteristics, long-term clinical outcomes, and procedure-related complications.
Results
A total of 545 patients were included in the analysis (HFLTV + RAP = 327 vs. HFLTV = 218). There were no significant differences in baseline characteristics between the groups. No differences were observed in procedural (HFLTV + RAP 74 [57–98] vs. HFLTV 66 [53–85.75] min, p = 0.617) and RF (HFLTV + RAP 15.15 [11.22–21.22] vs. HFLTV 13.99 [11.04–17.13] min, p = 0.620) times. Both groups showed a similar freedom from all-atrial arrhythmias at 12-month follow-up (HFLTV + RAP 82.68% vs. HFLTV 86.52%, HR = 1.43, 95% CI [0.94–2.16], p = 0.093). There were no significant differences in freedom from AF-related symptoms (HFLTV + RAP 91.4% vs. HFLTV 93.1%, p = 0.476) or AF-related hospitalizations (HFLTV + RAP 98.5% vs. HFLTV 97.2%, p = 0.320). Procedure-related complications were low in both groups (HFLTV + RAP 0.6% vs. HFLTV 0%, p = 0.247).
Conclusion
In patients undergoing RFCA for paroxysmal AF, adding RAP to HFLTV-ventilation was not associated with improved procedural and long-term clinical outcomes.
