Key result
Integrated CT and electroanatomic mapping successfully guides ablation of refractory left atrial ectopic tachycardia.
Why the study?
The use of integrated electroanatomic mapping with 3D multislice CT scan may improve the efficacy of catheter ablation in complex arrhythmic substrates where previous ablation attempts failed.
Population
A 25-year-old woman without structural heart disease with incessant left atrial tachycardia
Comparison
Integrated electroanatomic mapping with 3D multislice CT scan guided ablation vs previous conventional electroanatomic mapping guided ablation

The integration of 3D multislice CT scans with electroanatomic mapping systems can reveal singular anatomic findings and improve the efficacy of catheter ablation in complex arrhythmic substrates.
Pérez‐Castellano et al. (2007) conducted a case report in Incessant left atrial tachycardia (n=1). Integrated electroanatomic mapping with 3D multislice CT scan was evaluated on Successful ablation of ectopic focus. Integration of a 3D multislice CT scan with electroanatomic mapping successfully guided the ablation of an incessant left atrial ectopic focus in 1 patient after failed conventional attempts.
