Key result
FE-guided GP ablation by first-time operators takes ~35 minutes longer with fewer vagal responses vs high-volume operators.
Why the study?
Single-center observational studies showed promising results with FE-guided GP ablation in VMB patients, but data comparing first-time operators to high-volume operators were lacking.
Does FE-guided GP ablation performed by first-time operators have comparable procedural characteristics and syncope recurrence to a high-volume operator in patients with vagally mediated bradyarrhythmia?
Cohort (n=47)
Yes
Does FE-guided GP ablation performed by first-time operators have comparable procedural characteristics and syncope recurrence to a high-volume operator in patients with vagally mediated bradyarrhythmia?
Absolute Event Rate: 118% vs 83.4%
p-value: p=<0.001
FE-guided GP ablation for vagally mediated bradyarrhythmia is feasible and effective even when performed by procedure-naïve operators, despite longer procedure times.
No takes yet. Share an insight, caveat, or question.
Supports training first-time operators for FE-guided GP ablation in VMB; leaves open durability and generalizability versus high-volume centers.
Aksu et al. (2021) conducted a cohort in Vagally mediated bradyarrhythmia (n=47). FE-guided GP ablation by first-time operators vs. FE-guided GP ablation by a high-volume operator was evaluated on Procedure time (minutes) (p=<0.001). FE-guided GP ablation by first-time operators had longer procedure times (118.0 vs 83.4 min, p<0.001) and fewer positive vagal responses (62.5% vs 90.3%) compared to a high-volume operator.
