Abstract 5658: Acute Complication Rate with the Robotic Navigation for Catheter of Atrial Fibrilation: The Worldwide Experience
Introduction: The Hansen robotic system has recently been used for mapping and navigation during catheter ablation procedures in the atrial chambers. This system consists of a 14 French (F) outer sheath, and an 8 F inner robotic sheath manipulated via a remote station. Since this is relatively new technology information on safety are warranted. We report the worldwide experience in catheter ablation of atrial fibrillation (AF).
Methods: 601 consecutive patients underwent catheter ablation using the robotic system. Of them 466 patients were treated for atrial fibrillation. Data were prospectively collected, including intra-operative, early and late complications.
Results: Out of the 466 undergoing AF ablation, 364 were paroxysmal, 76 persistent and 16 permanent respectively. The remaining 115 patients underwent supraventricular arrhythmias ablation (83 flutters, 23 AVNRT and 9 WPW respectively). There was no procedure-related mortality. Vascular complications were reported in 0.7% of patients and in 1.3% of patients periricardial effusion occurred intra-operative or early after the procedures. Late complications were observed only in 4 patients (%) and included 2 pericarditis, 1 gastroparesis and 1 moderate pulmonary vein narrowing. Most complications occurred during the early period of the learning curve.
Conclusions: Hansen Robotic navigation demonstrated to be safe both for mapping and ablation in the left atrium. Complication rate appeared similar to what reported in the literature with manual catheter ablation.
