Key result
Electroanatomic mapping and entrainment pacing identified IART mechanisms, with successful ablation achieved at a site distant from the putative protected corridor in 50% of circuits.
Why the study?
Does electroanatomic mapping and entrainment pacing characterize IART mechanisms and guide ablation in patients with repaired congenital heart disease?

Does electroanatomic mapping and entrainment pacing characterize IART mechanisms and guide ablation in patients with repaired congenital heart disease?
Fusion of activation and entrainment data provides insight into specific IART mechanisms in congenital heart disease, revealing that successful ablation can often be achieved distant from the putative protected corridor.
Triedman et al. (2001) conducted an observational in Repaired Congenital Heart Disease and Intra-Atrial Reentrant Tachycardia (n=15). Electroanatomic mapping and entrainment pacing was evaluated on Successful ablation at a site distant from the putative protected corridor. Electroanatomic mapping and entrainment pacing identified IART mechanisms, with successful ablation achieved at a site distant from the putative protected corridor in 50% of circuits.
