Figure Lengend Snippet: The new algorithm is based on the concomitant use of the confidense TM module (automatic mapping, wavefront annotation, and pattern matching) and the CARTO prime TM parallel mapping module integrated in the CARTO prime TM software of the CARTO 3 system version 7 (biosense webster, Johnson & Johnson medical S.p.a., Irvine, CA). (A) The most stable QRS peak in one of the 12 ECG leads was chosen as reference for Pattern Matching (beat-to-beat analysis). (B) We set specific filters for the Confidense Module and these filters are the following: (a) pattern-matching should correlate at least 96% with the pre-excited QRS morphology (during Sinus rhythm, atrial pacing or antidromic tachycardia); (b) the mapping catheter should be stable in position and temporal activation (5 mm, 5 s); (c) the mapping catheter should have a contact force ≥3 grams with the endocardial tissue; (d) acquisition density should be set at the maximum level (<1 mm).
Article Snippet: This, in synergy with specific automated annotation algorithms integrated in the CARTO Prime TM software of the CARTO® 3 system, version 7 (Biosense Webster), defined the ablation target limiting the number and time of applications.
