Abstract:
Objective:To investigate the learning curve,radiation exposure,operation time and complications of 3D mapping system (Carto Univu) in radiofrequency ablation in treatment of patients with atrioventricular nodal reentrant tachycardia (AVNRT).Methods:The total radiation dose,total operation time,and surgical complications of radiofrequency ablation under the guide of Carto Univu (the Carto Univu group) in 70 patients with AVNRT were recorded during 6 months,and were compared with those of radiofrequency ablation under the guide of two-dimensional mapping technique (the 2D group).Results:There was no significant difference in the total operation time between the two groups.The total radiation dose in the Carto Univu group decreased compared with the two-dimensional group (P ＜ 0.05).The radiation time and radiation dose of the last 10 cases in the Carto Univu group were lower than the first 10 cases (P＜0.05).There were no operation complications in the both two groups.Conclusions:In AVNRT,fluoroscopy integrated 3D mapping contributes to a dramatic reduction in learning curve and radiation exposure without prolonging operation time or increasing complications.
