The inability of current catheter ablation procedures to accurately monitor lesion formation limits their safety and efficacy. An advanced fully integrated radiofrequency (RF)/optical coherence tomography (OCT) ablation catheter is developed, which enables real‐time monitoring during ablation. An OCT fiber array is especially designed, developed and integrated into an off‐the‐shelf irrigated RF ablation catheter. In‐vitro experimental studies performed on poultry and ovine hearts demonstrate the ability of the integrated RF/OCT system to provide information on the quality and orientation of catheter/wall contact. Experimental results show that adipose tissue can be accurately identified from normal myocardial tissue with 94% accuracy and lesion formation is monitored with an overall accuracy of 93%. The ability to predict pop events is also demonstrated, with an accuracy of 86%.

先进的全集成射频/光学相干断层扫描冲洗导管用于房颤消融

当前的导管消融程序无法准确地监测病变的形成，限制了其安全性和有效性。开发了一种先进的全集成射频（RF）/光学相干断层扫描（OCT）消融导管，可在消融期间进行实时监控。OCT光纤阵列是专门设计，开发并集成到现成的射频消融导管中的。在家禽和绵羊心脏上进行的体外实验研究表明，集成式RF / OCT系统能够提供有关导管/壁接触的质量和方向的信息。实验结果表明，可以从正常的心肌组织中准确识别出脂肪组织，准确度为94％，并且以93％的总体准确度监测病变的形成。
