Abstract:
Objective: To investigate the safety and efficacy of CARTO3 fast anatomical mapping during radiofrequency ablation in patients with paroxysmal atrial ifbrillation (PAF). Methods: A total of 120 PAF patients treated in our hospital from 2013-01 to 2015-07 were enrolled. All patients received CARTO3 system for mapping and they were randomly divided into 2 groups: Control group, the patients had selective pulmonary vein angiography, followed by conventional point by point method to reconstruct left atrial model for guiding the ablation of PFA and Treatment group, the patients had selective pulmonary vein angiography followed by fast anatomical mapping to build left atrial model for guiding the ablation of PFA; the rest operational steps such as trans-septal and circumferential pulmonary vein ablation were the same.n=60 in each group. The times of operation, X-ray exposure and the rates of success, complication occurrence were compared between 2 groups. Results: All patients were successfully completed radiofrequency ablation for PAF. Compared with Control group, Treatment group had increased modeling time (8.5 ± 3.6) min vs (5.2 ± 2.3) min, while decreased pulmonary vein ostium determing time (12.0 ± 5.6) min vs (25.0 ± 8.4) min, circumferential pulmonary vein ablation time (95.0 ± 22.0) min vs (115.0 ± 25.0) min and X-ray exposure time (15.0 ± 6.3) min vs (24.0 ±5.5) min, allP<0.05. The rates of success and complication occurrence were similar between 2 groups, P>0.05. Conclusion: CARTO3 fast anatomical mapping is safe and effective for guiding radiofrequency ablation in PAF patients, it may decrease the X-ray exposure time and operation time which were important for treating the relevant patients.
