Factor Information
Data ID 451
Factor Previous atrial fibrillation
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)
Association
Application prognosis
Objective analyze the long-term outcomes after intra-atrial re-entrant tachycardia (IART) ablation in congenital heart disease (CHD).
p Value <0.05
OR 3.08
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.
