J Am Coll CardiolPublished

  • Systematic review and pooled analysis of randomised trials

Authors' conclusion

Procedure-related complications and mortality rates associated with catheter ablation of AF are low and have declined in the past decade.

Study context

Population
Patients undergoing a first AF ablation (radiofrequency or cryoballoon) in RCTs, MEDLINE and EMBASE January 2013 to September 2022
Participants
15,701 patients · 89 studies
Outcome
Rate of procedure-related complications of AF catheter ablation

Pooled result

As reported in the abstract

Procedure-related complications
Overall complication rate
4.51% (95% CI: 3.76%-5.32%)
Severe complication rate
2.44% (95% CI: 1.98%-2.93%)
Vascular complications (most frequent)
1.31%
Pericardial effusion/tamponade
0.78%
Stroke/TIA
0.17%

Further pooled results

Procedure-related complication rate, by 5-year period of publication · significantly lower in the most recent period

P = 0.043

Pooled mortality, by 5-year period of publication

Pooled mortality stable over the 2 time periods (most recent vs earlier 5-year period)
0.06% vs 0.05%; P = 0.892

Complications by type

Vascular complications (most frequent)
1.31%
Pericardial effusion/tamponade
0.78%
Stroke/TIA
0.17%

Complication rate by AF pattern, ablation modality or strategy beyond pulmonary vein isolation

No significant difference in complication rate by AF pattern, ablation modality, or ablation strategies beyond pulmonary vein isolation
