This research project aims to advance engineering knowledge by applying an innovative, fibre-optics-based discrete optical coherence tomography to technology used for atrial fibrillation catheter ablation. RadioFrequency catheter-based ablation is far superior to cardiac drug therapy for atrial fibrillation patients. RadioFrequency catheters are not equipped with real-time lesion formation monitoring means, which enable the assessment of continuity-transmurality and prevent extra-cardiac complications, such as steam pops. Optical Coherece Tomography enables non-invasive, microscopic lesion formation assessment in real time during atrial fibrillation ablation procedures. The expected outcomes of this project are to develop a new hybrid fibre-optic/RadioFrequency catheter system and user-friendly driving software that will enable cardiac electrophysiologists to perform three key tasks not previously available.

该研究项目旨在通过将创新的基于光纤的离散光学相干断层扫描技术应用于房颤导管消融术来推进工程知识。射频导管消融治疗房颤患者的疗效远上级心脏药物治疗。射频导管未配备实时损伤形成监测装置，该装置能够评估连续透壁性并防止心外并发症，例如蒸汽爆裂。光学相干断层扫描能够在房颤消融术过程中真实的实时进行无创、微观损伤形成评估。该项目的预期成果是开发一种新的混合光纤/射频导管系统和用户友好的驱动软件，使心脏电生理学家能够执行以前没有的三项关键任务。
