Initial real-world data on catheter ablation in patients with persistent atrial fibrillation using the novel lattice-tip focal pulsed-field ablation catheter
Authors' conclusion
In terms of real-world data, our data confirmed AF ablation feasibility utilizing the lattice-tip focal PFA/RFA catheter in patients with persistent AF.
Study context
- Population
- Consecutive patients undergoing catheter ablation for persistent atrial fibrillation (AF)
- Participants
- 28 patients
- Outcome
- Acute procedural and periprocedural data (feasibility)
Methodological detailsconsecutive patients, single-arm, General anaesthesia (n = 6) or deep sedation (n = 22)
- Consecutive patients
- Single-arm
- General anaesthesia (n = 6) or deep sedation (n = 22)
Main finding
As reported in the abstract
- Additional linear ablations
- 21 patients (78%)
- Successful anterior line
- n = 13, 46%
- Successful roof line
- n = 19, 68%
- Median procedural time (IQR: 80-114) min
- 97
- Median fluoroscopic time (IQR: 7.2-9.5) min
- 8.5
Observational data: associations, not effects.
Further findings
Early recurrent AF within 90-day blanking period
- Early recurrent AF documented (incl. 1 during hospital stay)
- four patients (15%)
- 27 patients (96%) interviewed during follow-up
Safety
- Neither major nor minor procedural complication occurred
