Comparison of effects and safety of radiofrequency catheter ablation under different X-ray exposure modes in treating paroxysmal supraventricular tachycardia / 重庆医学

ABSTRACT

Objective To compare the curative effect and safety of non-X-ray fluoroscopic radiofrequency catheter ablation and conventional X-ray fluoroscopic radiofrequency catheter ablation in treating paroxysmal supraventricular tachycardia by Ensite Velocity three-dimensional electroanatomical mapping system.Methods One hundred cases diagnosed as paroxysmal supraventricular tachycardia in this hospital during 2014-2016 were selected and randomly divided into the control group (conventional X-ray exposure) and the experimental group(non-X-ray exposure by three-dimensional electroanatomical mapping system),50 cases in each group.The operation time,X-ray exposure time,complication rate,immediate and follow-up success rate were compared between two groups.Results There was no statistically significant difference in the operation time between the two groups (P＞0.05),but the X-ray exposure time in the experimental group [(0.46±0.14) min] was significantly lower than that of the control group [(13.87 ±4.03) min] and the complication rate (0 ％) was also significantly lower than that of the control group (8.00％);the immediate success rate (98.00 ％) was significantly was significantly decreased compared with the control group[(0.46± 0.14)min vs.(13.87 ±4.03)min],the complication rate was significantly lower than that in the control group(0 ％ vs.8 ％),the immediate success rate was significantly higher than that in the control group(98.00 ％ vs.84.00 ％),the follow up success rate was also significantly higher than that in the control group (94.00 ％ vs.74.00 ％),the differences were statistically significant (P＜0.05).Conclusion Using Ensite Velocity three-dimensional electroanatomical mapping system to conduct radiofrequency catheter ablation has an ideal clinical effect in the treatment of paroxysmal supraventricular tachycardia,which is safe and reliable.
