Electroanatomic Characterization of Conduction Barriers in Sinus/Atrially Paced Rhythm and Association with Intra‐Atrial Reentrant Tachycardia Circuits Following Congenital Heart Disease Surgery
Why the study?
Does electroanatomic mapping in sinus/atrially paced rhythm identify conduction barriers associated with IART circuits in patients with repaired congenital heart disease?
Population

Implication
May enable IART ablation without inducing tachycardia; case-report data leaves open prospective validation.
Structured PICO
Does electroanatomic mapping in sinus/atrially paced rhythm identify conduction barriers associated with IART circuits in patients with repaired congenital heart disease?
P
Population
18 patients with intra-atrial reentrant tachycardia (IART) and a remote history of repaired or palliated congenital heart disease (8 biventricular repair, 8 single ventricle palliation [7 Fontan], and 2 Mustard repair)
I
Intervention
Electroanatomic mapping in sinus or atrially paced rhythm
O
Outcome
Identification of electrical barriers in sinus/atrially paced rhythm and their association with IART circuitssurrogate
Electroanatomic mapping during sinus or atrially paced rhythm can identify conduction barriers that serve as central obstacles for IART, potentially guiding ablation without relying on spontaneous tachycardia initiation.
