Abstract

Atrial fibrillation (AF) is the most common arrhythmia and results in an increased risk of ischemic stroke. Recently, a european consortium has developed a new minimally invasive device for surgical AF treatment. It consists of a micro-robot holding an end-effector called "umbrella" containing 22 radiofrequency powered electrodes. Surgery using this new device can only be performed having an appropriate navigation technique. Therefore, we have developed an image-based navigation workflow and a prototypic navigation application. First, a navigation workflow including an appropriate intra-operative image-modality was defined. Intraoperative ultrasound became the imaging modality of choice. Once the umbrella is unfolded inside the left atrium, data is acquired and segmented. Using a reliable communication protocol, mobility values are transferred from the control software to the navigation system. A deformation model predicts the behavior of the umbrella during repositioning. Prior to surgery, desired ablation lines can be interactively planned and actually made ablation lines are visualized during surgery. Several in-vitro tests were performed. The navigation prototype has been integrated and tested within the overall system successfully. Image acquisitions of the umbrella showed the feasibility of the navigation procedure. More in-vitro and in-vivo tests are currently performed to make the new device and the described navigation procedure ready for clinical use.
