| Factor | intra-atrial re- entrant tachycardia(IART) different than isolated cavotricuspid isthmus(CTI) in all follow-up |
| Description | IART increases morbidity and mortality in CHD patients. Radiofrequency catheter ablation has evolved into the first-line treatment of this complication. |
| Biomarker | NA |
| Classification | A3 (clinical factor - disease & symptom) |

| Application | prognosis |
| Objective | analyze the long-term outcomes after intra-atrial re-entrant tachycardia (IART) ablation in congenital heart disease (CHD). |
| p Value | 0.03 |
| HR | 3.37 |
| Conclusion | Ablation of IART in CHD is a challenging procedure, but after ablation in experienced centers, SR can be maintained in 78.3%. Predictors of recurrences are non-CTI–related IART, long PR interval, and previous or induced AF. A risk score based on these factors can be useful for recurrence prediction. |
