The impact of the CartoUnivu™ technology (Biosense Webster, Diamond Bar, CA, USA) on fluoroscopy exposure compared to a conventional approach using electroanatomical mapping (Carto 3™) was evaluated in patients undergoing radiofrequency ablation for ventricular tachyarrhythmias (VT).
We prospectively evaluated 23 patients undergoing VT ablation using the CartoUnivu™ technology. The CartoUnivu™ Module integrates fluoroscopic images and cine loops into the electroanatomical mapping system. As a control group, 23 out of 88 VT patients (ablated using conventional fluoroscopy supplemented by electromagnetic mapping with the Carto 3™ System) were matched for age, gender, body surface area, operator, redo-procedure, presence of coronary artery disease, and left ventricular dysfunction using propensity score matching. A significant reduction in fluoroscopy exposure was observed in the CartoUnivu™ group when compared to the conventional group (10.57 ± 7.93 minutes vs 18.52 ± 11.24 minutes, P_= 0.008; 611 cGy/cm(2) vs 1650 cGy/cm(2) , P = 0.001). In multivariate analysis, the CartoUnivu™ module was an independent predictor of reduced fluoroscopy use.
This is a report on the clinical application of the CartoUnivu system for VT ablation. CartoUnivu™ markedly reduced fluoroscopy time and dose compared to conventional fluoroscopy/electroanatomical mapping.
在接受室性心律失常（VT）射频消融的患者中，评估了CartoUnivu™技术（美国加利福尼亚州钻石吧市Biosense Webster公司）与使用电解剖标测（Carto 3™）的传统方法相比对透视曝光的影响。
我们前瞻性地评估了23例使用CartoUnivu™技术进行VT消融的患者。CartoUnivu™模块将透视图像和电影环整合到电解剖标测系统中。作为对照组，使用倾向评分匹配法，从88例VT患者（使用传统透视并辅以Carto 3™系统的电磁标测进行消融）中选取23例在年龄、性别、体表面积、操作者、再次手术、冠状动脉疾病的存在情况以及左心室功能障碍方面进行匹配。与传统组相比，CartoUnivu™组的透视曝光显著减少（10.57±7.93分钟对18.52±11.24分钟，P = 0.008；611 cGy/cm²对1650 cGy/cm²，P = 0.001）。在多变量分析中，CartoUnivu™模块是减少透视使用的独立预测因素。
这是一篇关于CartoUnivu系统在VT消融临床应用的报告。与传统透视/电解剖标测相比，CartoUnivu™显著减少了透视时间和剂量。
