Outcome of repeat ablation for premature ventricular contractions in patients with prior ablation failure: Impact of advanced techniques
Authors' conclusion
Although success is lower for patients with prior failed ablation, repeat ablation seems reasonable for many, and the use of advanced techniques increased success to 71% in this group.
Study context
- Population
- Consecutive patients undergoing ablation for premature ventricular contractions75 (31%) with prior failed ablation
- Participants
- 239 patients
- Exposure
- Repeat PVC ablation after prior failed ablation vs first ablation
- Prior failed ablationn = 75
- Outcome
- Acute success (abolition of the target PVC) and long-term outcome of repeat ablation
Methodological detailsconsecutive patients
- Consecutive patients
Main finding
As reported in the abstract
Acute success of standard ablation
P < 0.001
Observational data: associations, not effects.
Further findings
Long-term recurrence after standard ablation
P < 0.05
