Abstract：Objective To compare the feasibility of non-X-ray fluoroscopic radiofrequency catheter ablation (RFCA) and routine X-ray fluoroscopic RFCA for treating paroxysmal supraventricular tachycardia (PSVT) guided by Ensite Velocity 3D electroanatomical mapping system, and discuss the application value of 3D electroanatomical mapping system in diagnosis and treatment of PSVT.Methods The patients with PSVT and planed RFCA (n=86) were chosen and randomly divided into 3D group (n=45) given treatment of non-X-ray fluoroscopic RFCA guided by Ensite Velocity 3D electroanatomical mapping system, and routine group (n=41) given treatment of X-ray fluoroscopic RFCA. The procedure time, X-ray fluoroscopic time, immediate success rate, incidence of complications and follow-up success rate were compared between 2 groups.Results The procedure time was similar (P>0.05), X-ray fluoroscopic time decreased significantly (P<0.05), immediate success rate and follow-up success rate increased significantly (P<0.05) and incidence of complications decreased significantly (P<0.05) in 3D group compared with routine group.Conclusion 3D electroanatomical mapping system is safe and effective in treatment of PSVT with RFCA, which can be tried to apply for minimizing X-ray fluoroscopy.
