Remote magnetic navigation for ablation of typical atrial flutter: Long-term results

open access: yesRevista Portuguesa de Cardiologia (English Edition), 2014
Remote magnetic navigation has proved to be effective in the ablation of most supraventricular and ventricular arrhythmias. Initial studies reported worse results with this system compared to conventional ablation for atrial flutter. The aim of this study was to assess the acute and long-term success of atrial flutter ablation with remote magnetic ...
