Background:
This study aims to report on the clinical and patient-reported outcomes in patients undergoing atrial fibrillation (AF) ablation with moderate or severe complications.
Methods:
The prospective, multicentre German Ablation Registry of patients undergoing catheter ablation was studied to compare outcomes of patients with moderate or severe complications (group I) and patients without or minor complications (group II).
Results:
A total of 3865 patients (group I = 158, group II = 3707) were included in this analysis. Procedural success (92.4% vs 96.1%, p = 0.019) was lower and arrhythmia recurrence before discharge significantly higher in group I (15.8% vs 6.5%, p < 0.001). Hospital stays were longer in in group I (6 days vs 3 days, p < 0.001). The in-hospital rate of death, myocardial infarction (MI) or stroke was 6.4% in group I. Age was an independent predictor of in-hospital complications (HR1.43, 95% CI 1.18-1.72). In the 1-year follow-up, the composite outcome of death, MI, stroke, or major bleeding (8.5% vs 1.5%, p < 0.001) was significantly higher in group I. The majority of patients were still feeling safe during treatment regardless of occurred complications (88.4% vs 94.0%, p = 0.14) and would choose the same centre again in most cases (90.7% vs 92.9%, p = 0.59). Patients reported no or improved symptoms in both cohorts (77.3% vs 78.6%) without significant differences.
Conclusion:
Cardiovascular events in patients with severe complications are more common but patient satisfaction and symptomatic relief are high and comparable to those without complications.
