Key result
Three-dimensional electroanatomic mapping using a minimally invasive simplified approach successfully guided ablation in 87% of macro-reentrant and 90% of focal atrial tachycardias in CHD patients.

Does three-dimensional electroanatomic mapping with a minimally invasive approach improve ablation success of atrial tachycardias in patients with repaired congenital heart disease?
A minimally invasive 3D electroanatomic mapping approach with limited catheters is highly effective for guiding ablation of atrial tachycardias in patients with repaired congenital heart disease.
Drago et al. (2011) conducted an observational in Atrial tachycardia after repair of congenital heart disease (n=31). Three-dimensional electroanatomic mapping (EAM) guided ablation was evaluated on Successful ablation of atrial tachycardias. Three-dimensional electroanatomic mapping using a minimally invasive simplified approach successfully guided ablation in 87% of macro-reentrant and 90% of focal atrial tachycardias in CHD patients.
