Key result
Radiofrequency ablation of IART achieves ~79% acute procedural success and improves clinical severity scores.
Why the study?
RFCA of IART is difficult, and the influence of patient factors, procedural factors, and novel technologies on outcomes was unknown.
What factors are associated with acute and chronic outcomes of radiofrequency catheter ablation of intra-atrial re-entrant tachycardia in patients with congenital heart disease?

In patients with congenital heart disease and IART, radiofrequency catheter ablation provides effective symptom palliation despite a high recurrence rate, with acute success improved by irrigated ablation.
Triedman et al. (2002) conducted an observational in Congenital heart disease and intra-atrial re-entrant tachycardia (n=134). Radiofrequency catheter ablation (RFCA) was evaluated on Acute procedural success (ablation of ≥1 IART circuit). Radiofrequency catheter ablation of intra-atrial re-entrant tachycardia achieved acute success in 79% of procedures, with significant improvement in clinical severity scores (P<0.0001).
