We sought to evaluate whether the use of a new nonfluroscopic mapping (NFM) system, the KODEX\u2010EPD, is able to reduce FT and PT when mapping is performed by the pacing catheter rather than an electrophysiological mapping catheter.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>We included 46 consecutive patients (77\u2009\u00b1\u20098\u2009years; 63% male) who underwent HBP; in 22 a NFM\u2010guided procedure with the KODEX\u2010EPD system was performed (group 1), whereas in 24 a conventional fluoroscopy\u2010guided approach was used (group 2). Pacing indications were sick sinus syndrome in 13, atrioventricular block in 21, and cardiac resynchronization therapy in 12 cases. Both a lumen\u2010less fixed helix lead and a stylet\u2010driven extendable helix lead were used, respectively, in 24% and 76% of patients. HBP was successful in 22 patients (100%) in group 1 and 23 patients (96%) in group 2.
