Arrhythmia following convergent ablation in subgroups
| Outcome | PsAF duration >1 year | LA diameter >50 mm | LVEF ≤40% | BMI >30 kg/m2 | Previous AF ablation |
|---|---|---|---|---|---|
| (n = 52) | (n = 19) | (n = 12) | (n = 33) | (n = 26) | |
| AF recurrence at 1 year, % (n) | 17.3 (9) | 26.3 (5) | 16.7 (2) | 18.8 (6) | 15.4 (4) |
| Overall AF recurrence, % (n) | 38.5 (20) | 63.2 (12) | 50.0 (6) | 27.3 (9) | 46.2 (12) |
| Overall occurrence of AF/AT/AFL, % (n) | 51.9 (27) | 73.7 (14) | 50.0 (6) | 45.5 (15) | 61.5 (16) |
AF: atrial fibrillation; AFL: atrial flutter; AT: atrial tachycardia; BMI: body mass index; LA: left atrium; LVEF: left ventricular ejection fraction; PsAF: persistent atrial fibrillation.
