Key result
EnSite-array guided catheter ablation successfully eliminated 98.6% (73 of 74) of atrial tachycardias without complications, with no recurrences during 16±9 months of follow-up.

EnSite-array guided catheter ablation is a highly successful and safe method for mapping and eliminating atrial tachycardias, including those in patients with prior cardiac surgery.
arita al 1 report on EnSite-array (ESA) guided catheter ablation in 51 patients with 74 atrial tachycardias 14 patients had undergone previous open heart surgery and 5 had organic heart disease.AT was either focal (n=48) or macroreentrant (n=26), and originated from the right atrium in 77% or the left atrium in 23% according to noncontact mapping with the ESA system.All but 1 AT were successfully eliminated without complications.Fluoroscopic time was 19±11 min, the number of radiofrequency applications was 8±7, and radiofrequency energy was 10,711±12,655 J.The patients were free from recurrence during follow-up of 16±9 months.With such a high success rate, the authors imply the usefulness of the ESA for quick and precise determination of the origin of ATs. 1
