A Case Control Study On The Influence Of Radiofrequency Catheter Ablation Of Atrial Fibrillation Between The Neotype And The Traditional3D Mapping Electroanatomicsystem

Objective:To evaluate the influenceon the radiofrequency catheter ablation of atrialfibrillation between the neotype and the traditional3Dmapping electroanatomic system.Methods The study population consisted of173consecutive patients suffering fromparoxysmal or persistent AF(atrial fibrillation)in our center from2011.10～2012.7.117Paroxysmal AF patients(mean age60.7±8.2years,69male;46patients useCARTO3systerm);56persistent AF patients(mean age55.4±9.3years,47male;35patients use CARTO3systerm,).Divide all the patients into4groups:CARTO3paroxysmal AF-Group A(46patients),CARTO-XP paroxysmal AF-Group B(71patients),CARTO3persistentAF-Group C(31patients),CARTO-XP persistentAF-GroupD(25patients).Recordthe information including fluoroscopytime,radiofrequencyduration,procedure duration,the success rate of the ablation,the incidence ofcomplications.Results There were no differences in any clinical characteristics(age, sex, left atriumdiameter, LVEFand heart disease) among the4study groups. A mean of4.0±0.3PVs/patient were identified in Group A and a mean of4.1+0.2PVs/patient wereidentified in Group B (P=0.22).while, A mean of4.1±0.3PVs/patient were identified inGroup C and a mean of4.1+0.3PVs/patient were identified in Group D (P=0.17).Mean fluoroscopic time was significantly reduced in Group A as compared withGroup B（16.1±12.8min vs20.2±10.6min，P＝0.03）,the same result could be seenbetween Group C and Group D（25.6±11.8min vs34.7±13.8min，P＜0.01）.But it seemsthat CARTO3systerm didn’t have the same effect to the radiofrequency duration（GroupA41.2±10.5min vs Group B46.4±14.2min，P＞0.05；Group C61.4±11.8min vs GroupD76.2±19.8min，P＞0.05）andthe procedural duration（Group A100.8±16.2min vs Group B110.4±20.6min，P＝0.07；Group C144.8±36.6min vs Group D153.4±38.3min，P＝0.09）. There was no serious radiofrequency ablation-associated complications in allPatients.The incidence of complications: Group A-2.2%,GroupB-4.2（%P=0.55）; GroupC-11.4%,Group D-19%(P=0.43).The total incidence of complications was6.9%.Thesuccess rate of ablation:Group A-91.3%,GroupB-88.7%（P=0.19）;Group C-80%,GroupD-76.2%(P=0.74).The total success rate of ablation was86.1%.Conclusion The neotype3Dmapping electroanatomicsysterm could significantly reducefluoroscopic time while maintaining the safety and efficacy of radiofrequency catheterablation.
