Key result
Integrating multislice computed tomography into electroanatomic mapping improved procedural success for atrial fibrillation ablation compared to conventional mapping (85.1% vs 67.9%; P=0.018).
Why the study?

Absolute Event Rate: 85.1% vs 67.9%
p-value: p=0.018
Integrating multislice CT into 3D electroanatomic mapping significantly improves procedural success and may reduce the risk of pulmonary vein stenosis during radiofrequency ablation for atrial fibrillation.
Martinek et al. (2007) conducted a cohort in Multi-drug-resistant atrial fibrillation (n=100). Multislice computed tomography image integration into electroanatomic mapping vs. Conventional three-dimensional electroanatomic mapping was evaluated on Procedural success (p=0.018). Integrating multislice computed tomography into electroanatomic mapping improved procedural success for atrial fibrillation ablation compared to conventional mapping (85.1% vs 67.9%; P=0.018).
