| Factor | systemic ventricle dilation |
| Description | Predictors of acute radiofrequency catheter ablation failure were as follows: nonrelated cavotricuspid isthmus IART, previous atrial fibrillation, transposition of great arteries and systemic ventricle dilation with an area under the receiver operating characteristic curve of 0.83±0.056 (CI, 0.74–0.93, P=0.001). |

| 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). |
