A new dielectric-based method (KODEX-EPD mapping system, EPD Solutions, a Philips company) for measuring tissue thickness at the catheter-tissue interface has recently been developed. We reported preliminarydata on real-time catheter-based measuring myocardial wall thickness in vivo, during typical atrial flutter radio frequency ablation.
The study population consisted of 12 consecutive patients, suffering from symptomatic paroxysmal or persistent cavo-tricuspid isthmus dependent, counter clockwise and clockwise AFL, under going a first catheter ablation between April 2021 and November 2021. The new KODEX-EPD function, Wall Viever, was used to calculate atrialwall thickness. The atrial wall thickness was significantly higher closeto the tricuspid annulus than close to the inferior vena cava (3.6 ± 0.5 mm vs 2.4 ± 0.3 mm, p < .001) and a trend towards a progressive decrease of atrial wall thickness was observed moving the mapping catheter from the tricuspidvalve to the inferior vena cava.
Thenew KODEX-EPD function, Wall Viever, allowed us to assess atrial wall thickness during atrial flutter radio frequency ablation.
最近开发了一种新的基于介电的方法(KODEX-EPD 映射系统,EPD Solutions,Philips 公司),用于测量导管 - 组织界面处的组织厚度。我们报告了在典型的房性扑动射频消融过程中实时基于导管测量活体心肌壁厚度的初步数据。
该研究人群包括 12 例连续患者,他们患有症状性阵发性或持续性腔静脉 - 三尖瓣峡部依赖性、逆时针和顺时针房扑,在 2021 年 4 月至 2021 年 11 月期间首次接受导管消融。新的 KODEX-EPD 功能“壁视图”(Wall Viever)用于计算心房壁厚度。心房壁厚度在靠近三尖瓣环处明显高于靠近下腔静脉处(3.6±0.5mm 比 2.4±0.3mm,p<0.001),并且观察到随着从三尖瓣到下腔静脉移动映射导管,心房壁厚度呈逐渐降低的趋势。
新的 KODEX-EPD 功能“壁视图”(Wall Viever)允许我们在房扑射频消融期间评估心房壁厚度。
