![]() ![]() Radiation emanating from the ablated seed material is detected to analyze ablation effects without disturbing the ablation surface. When subjected to ablation conditions, the seed material is ablated. (Inventor)Īn ablation article, such as a conical heat shield, having an ablating surface is provided with at least one discrete area of at least one seed material, such as aluminum. The RMN catheters have a flexible design enabling them to access otherwise difficult anatomy including the posterior tricuspid annulus and posterior RVOT.Įrickson, W. The RMN is more effective in selected patients with recurrent idiopathic VA after failed manual ablation and is associated with less fluoroscopy time. Neither groups exhibited any major complications. Successful ablation rate in the posterior right ventricular outflow tract (RVOT) plus posterior-tricuspid annulus was higher with RMN as compared with manual ablation (92 vs. Overall, successful ablation rate was significantly higher using RMN as compared with manual ablation (91 vs. Among these patients, 22 (43Â %) underwent repeat ablation with the RMN and 29 (57Â %) underwent repeat ablation with a manual ablation. We analyzed the clinical characteristics, including the successful ablation site and findings at electrophysiology study, in repeat procedures conducted using RMN as compared with manual ablation. ![]() Among 235 patients with idiopathic VA referred for catheter ablation, we identified 51 patients who were referred for repeat ablation after a failed manual ablation. We describe the efficacy of the RMN for ablation of idiopathic VA after failed manual ablation. The remote magnetic navigation (RMN) catheter has a flexible catheter design allowing access to difficult anatomy. Kawamura, Mitsuharu Scheinman, Melvin M Tseng, Zian H Lee, Byron K Marcus, Gregory M Badhwar, NitishĬatheter ablation for idiopathic ventricular arrhythmia (VA) is effective and safe, but efficacy is frequently limited due to an epicardial origin and difficult anatomy. Comparison of remote magnetic navigation ablation and manual ablation of idiopathic ventricular arrhythmia after failed manual ablation. ![]()
