Does the 'Astrocard' navigation system with CT integration improve procedural times in patients undergoing ablation for atrial fibrillation and flutter?
The integration of cardiac CT with the Astrocard navigation system allows for accurate electroanatomical mapping and may minimize fluoroscopy and operation times during ablation for atrial arrhythmias.

May shorten AF ablation times with CT-integrated Astrocard navigation; leaves open confirmation in randomized trials.
Aim. The first experience of the application of the integration algorithm for computed tomography of the heart with the navigation system “Astrocard” (Russia) when performing radiofrequency ablation in patients with atrial fibrillation and flutter.Material and Methods. A total of 31 patients with atrial fibrillation and two patients with atypical left atrial flutter were subjected to electroanatomical reconstruction of the left atrium and pulmonary veins with computed tomography of the heart. In patients with atrial fibrillation, an ablation scheme involved for antral isolation of the pulmonary veins. In patients with atypical left atrial flutter, linear ablation was applied in the area of slow conduction. The duration of the operation was 58±14.5 min, and the time of fluoroscopy was 33±8 min.Conclusion. The merge function of the “Astrocard” navigation mapping system (Russia) provided an accurate comparison of the electroanatomical map with the computed tomography of the heart, which allowed us to minimize the time of fluoroscopy and the time of operation.
