Ablation of atrial fibrillation using CT image integration

Abstract

In our case report we describe a catheter ablation in a patient with symptomatic, drug-refractory atrial fibrillation using the new CT image integrating mapping technology. Using image integration an arrhythmogenic right inferior pulmonary vein was revealed which was not found during conventional 3-dimensional mapping. Thereby we want to demonstrate potential impacts on safety and effectiveness of ablation strategies using an image integration technology, especially in cases of difficult anatomic variations.

“…Selective radiofrequency ablation is a treatment choice of atrial fi brillation. Correct PVs mapping has an important role on the success of ablation procedures [1,3]. CT angiography (CTA) has become an increasingly important noninvasive modality in the diagnosis of coronary artery diseases, including the non-coronary vascular structures of the heart.…”
