Abstract
Background The aim of this analysis was to investigate whether electroanatomical 3D map and CT/MRI image integration using the CartoMerge module improves efficacy, reduces procedure time or fluoroscopy usage. Material and methods 57 patients undergoing pulmonary vein isolation (PVI) were divided in the “Merge” (n=45 pts) and “non-Merge” (n=14pts) groups depending on usage of image integration. PV isolation during procedure (acute PVI), procedure time, fluoroscopy time, number of radio frequency (RF) applications and AF recurrence during follow-up (Merge group:12-24 months, non-Merge group: 9-18 months) were analyzed. Results Intra-procedural PV was equal in both groups (93%). Long-term efficacy, defined as absence of AF recurrence, was insignificantly higher in the Merge group (69,8% vs 50%, p=0,11793). Procedure time was significantly longer in the Merge group – 239,1 (±55,5) min. vs 192,4 (±44,5). Fluoroscopy time was similar in both groups 29,9 (±12,23) vs 24,6 (±26,5) min, (p=0,579). Number of RF applications was significantly higher in the Merge group 48,5 (±25,2) vs 27,2 (±14,9). Conclusions CartoMerge did not improve the rate of acute PVI, long-term effectivity or fluoroscopy time. In the non-Merge group the procedure time was shorter and the number of RF applications was significantly smaller.
