Computed tomographic integration into electroanatomic mapping may be useful in determining the anatomy to allow successful ablation of inferoseptal accessory pathways.
Case Report
Integration of computed tomography into electroanatomic mapping may be useful for determining the complex anatomy of inferoseptal accessory pathways associated with coronary sinus aneurysms to facilitate successful ablation.
Inferoseptal accessory pathways are associated in some cases with a coronary sinus (CS) aneurysm or diverticulum.1,2 A single aneurysm of the CS or its tributaries has been detected in 9% of patients treated for inferoseptal accessory pathways.3,4 Whereas ablation of accessory atrioventricular (AV) pathways has a high success rate, ablation of inferoseptal accessory pathways is difficult compared to ablation at other locations.5,6 Electrophysiologists need detailed anatomic knowledge of the inferoseptal space, and hopefully computed tomographic (CT) integration into electroanatomic mapping would be useful in determining the anatomy to allow successful ablation.
Nishimori et al. (Fri,) conducted a case report in Inferoseptal accessory pathways associated with a coronary sinus aneurysm. Computed tomographic (CT) integration into electroanatomic mapping was evaluated. Computed tomographic integration into electroanatomic mapping may be useful in determining the anatomy to allow successful ablation of inferoseptal accessory pathways.
