| Factor | No. (intra-atrial re-entrant tachycardia)IART induced |
| Description | 114 IART were ablated (acute success: 74.6%; 1.21±0.41 IART per patient) with an acute success of 74.5%. Cavotricuspid isthmus–related IART was the only arrhythmia in 51%; non–cavotricuspid isthmus–related IART was the only mechanism in 27.7% and 21.3% of the patients had both types of IART |

| 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). |
