Automatic magnetic-guided electroanatomical mapping and remote-controlled ablation of atypical and typical atrial flutter.
Two patients with inconclusive surface electrocardiogram patterns underwent nonfluoroscopy automatic mapping and remote-controlled ablation of nonisthmus and isthmus-dependent right atrial flutter.


RESULTS
A 0.08 magnetic vector force and a motor drive enable a complex steering of a new 8-mm magnet tip electrode. The navigation system performs atrial electroanatomical mapping fully automatically. Total procedural fluoroscopy time for ablation of nonisthmus-related atypical and isthmus-dependent flutter was 8.5 and 3.2 minutes, respectively.


CONCLUSIONS
Automatic electroanatomical mapping offers a promising option to effectively guide the remote-controlled ablation of atrial reentry tachycardias and to reduce fluoroscopy time.
