Coronary artery disease in atrial fibrillation ablation: impact on arrhythmic outcomes
Authors' conclusion
In patients undergoing CT scan before AF ablation, critical CAD was diagnosed in 7.1% of patients. Coronary artery disease and revascularization were not independent predictors of recurrence
Study context
- Population
- Patients with atrial fibrillation (AF) undergoing first cryoballoon catheter ablation (CA) with contrast computed tomography (CT) pre-ablation, Universitair Ziekenhuis Brussel, Belgium, 2015–2019
- Participants
- 576 consecutive patients
- Exposure
- Coronary artery disease (CAD) vs no CAD on pre-ablation CT
- Critical CADn = 41
- CADn = 122
- Outcome
- Prevalence of CAD detected by cardiac CT pre-ablation; impact of CAD and revascularization on outcomes after AF ablation
Methodological detailssingle-centre, consecutive patients
- Single-centre
- Consecutive patients
