After one year of follow-up, 23 patients (79%) had no recurrence of arrhythmia. 9/29, p=0.016) and of combined AF and atypical AFL inducibility (19 vs. There was a significant reduction of AF inducibility (16 vs. After CTI ablation, only 11 patients (38%) maintained arrhythmia inducibility (p<0.001)-AF in nine and atypical AFL in two. Better yet, CPT 2013 does not restrict us from reporting this add-on code just one time. Of the 29 patients, 26 (90%) had an inducible arrhythmia before CTI ablation-AF in 16, typical atrial flutter (AFL) in seven and atypical AFL in three. Code 93657 is used to report additional linear or focal intracardiac catheter ablation of left or right atrium for treatment of atrial fibrillation remaining after completion of pulmonary vein isolation. Atrial arrhythmias were considered inducible if they persisted for more than 60 seconds. Atrial arrhythmia inducibility was tested with burst pacing down to 150 ms or atrial refractoriness from the proximal coronary sinus. The procedure was performed using a CARTO-Merge mapping system, one or two Lasso catheters, an irrigated ablation catheter and radiofrequency energy. In 29 consecutive patients (23 male, mean age 54.6+/-11.4 years, 11 (38%) with hypertension and four (14%) with structural heart disease, mean left atrial dimension 43+/-6 mm) undergoing PV isolation for paroxysmal or persistent AF, atrial arrhythmia inducibility was tested before and after CTI ablation. The aim of this study is to assess whether CTI ablation after PV isolation reduces inducibility of atrial arrhythmias, particularly AF. Non-inducibility after AF ablation is associated with a higher success rate. A cavotricuspid isthmus (CTI) block may be an easier and safer alternative to left atrial lines for this purpose. In AF ablation, after pulmonary vein (PV) isolation, substrate modification can be increased by performing linear lesions in the left atrium that reduce the fibrillatory surface. Maintenance of atrial fibrillation (AF) depends on the presence of multiple reentrant circuits in the atria.
