| Factor | previous atrial fibrillation |
| Description | Predictors of acute radiofrequency catheter ablation(RF) failure were as follows: nonrelated cavotricuspid isthmus IART, previous atrial fibrillation. |

| Conclusion | Although ablation in CHD is a challenging procedure, acute success of 75% can be achieved in moderate–highly complex CHD patients in a referral center. Predictors of failed ablation are IART different from cavotricuspid isthmus, previous atrial fibrillation, and markers of complex CHD (transposition of great arteries, systemic ventricle dilation). |
