Comparison between conventional mapping and 3D electrode balloon mapping in guiding radiofrequency ablation of right ventricular septum premature ventricular contraction
Abstract：Objective To compare the effect of radiofrequency ablation of idiopathic right ventricular septum premature ventricular contraction separately in the guidance of conventional electrophysiological mapping and Ensite array electrode balloon mapping.MethodsEighty-eight patients with right ventricular septum premature ventricular contraction were divided into two groups, where 39 cases were mapped in conventional method and 49 cases adopted Ensite array electrode balloon mapping. Between the two groups, target mapping time, X-ray exposure time, ablation time, the total time of surgery and curative effect in the follow-up were all compared during the ablation. ResultsCompared with conventional electrophysiological mapping group, the target mapping time, X-ray exposure time, ablation time and the total time of surgery of Ensite array electrode balloon mapping were all significantly shortened(P<0.01). The immediate success rates of the two groups were all 100%. In the follow-up after one month, 5 cases in the conventional electrophysiological mapping group and one case in the Ensite array electrode balloon mapping group got palindromia of premature ventricular contraction.ConclusionEnsite array electrode balloon mapping is able to shorten the time of surgery and reduce the recurrence rate.
