This nationwide cohort study suggests a higher risk of AF recurrence with CS during CA compared to GA.
Study context
- Population
- Adults (≥18 years) undergoing first-time catheter ablation for atrial fibrillation (AF) in Denmark, 2010–2018
- Participants
- 7,957 adults
- Exposure
- Conscious sedation vs general anaesthesia during first-time AF catheter ablation
- Conscious sedation (CS)n = 6,421
- General anaesthesia (GA)n = 1,536reference
- Outcome
