BACKGROUND
Compatibility of DiamondTemp (DT) radiofrequency (RF) catheter with the Rhythmia mapping system has not been manufacturer-reported nor its tracking accuracy reported.
METHODS
Consecutive patients undergoing macroreentrant atrial tachycardia ablation guided by Rhythmia and ablated using DT were prospectively enrolled. Following catheter configuration, ablation lines were performed and remapped to measure the RF tag to effective-ablation-line-center (RFT-ALC) distance.
RESULTS
Among 20 consecutive patients (54 maps), 40 ablation lines were evaluated. Overall, the RFT-ALC distance was 3.88 ± 2.95 mm, and the operator assessment of accuracy was high. No complications occurred.
CONCLUSION
The use of DT catheter guided by the Rhythmia mapping system is feasible and accurate.
背景
DiamondTemp（DT）射频（RF）导管与Rhythmia标测系统的兼容性尚未见制造商报告，其跟踪准确性也未报告。
方法
前瞻性纳入连续接受Rhythmia指导下的大折返性房性心动过速消融且使用DT进行消融的患者。导管配置完成后，进行消融线操作并重新标测以测量射频标签到有效消融线中心（RFT-ALC）的距离。
结果
在连续20例患者（54张标测图）中，评估了40条消融线。总体而言，RFT-ALC距离为3.88±2.95毫米，术者对准确性的评估较高。未发生并发症。
结论
在Rhythmia标测系统指导下使用DT导管是可行且准确的。
