      Jennifer Riccio, Esther Pueyo and Pablo Laguna participated in\u00a0Atrial Signals congress<\/strong>\u00a0that took place at the Karlsruhe Institute of Technology (KIT), Campus South, Karlsruhe, Alemania, from Septembre 23 to 25.<\/p>\n

      Researcher Jennifer Riccio explained her work about\u00a0\u201cAnalysis of unipolar electrogram eigenvalue dispersion\u00a0for the detection of atrial fibrosis”.<\/strong><\/p>\n

      Atrial fibrosis plays a meaningful role in the pathogenesis of atrial fibrillation (AF). Areas with peak-to-peak amplitude of bipolar\u00a0electrograms<\/strong>\u00a0(b-EGMs) lower than 0.5 mV are detected as scar tissue and targeted for AF ablation procedures. However, this approach disregards the spatiotemporal information held in the signal and is influenced by b-EGMs dependence on\u00a0catheter<\/strong>\u00a0orientation.<\/p>\n

      To overcome these limitations, in this study, we propose to use the dominant-to-remaining eigenvalue dominance ratio (EIGDR) of unipolar electrograms (u-EGMs) within a group of\u00a0nearby electrodes<\/strong>\u00a0(clique) as a measure of the voltage wavefront roughness and correlate it with the presence of fibrosis.<\/p>\n

      EIGDR approach allows to discriminate\u00a0fibrotic from non-fibrotic tissue<\/strong>, improving its performance when clique alignment is considered and 3\u00d73 configuration is used, providing slightly improved performance to standard voltage maps for the 3\u00d73 aligned EIGDR maps.<\/p>\n

      In addition,\u00a0Esther Pueyo<\/strong>\u00a0and\u00a0Pablo Laguna<\/strong>\u00a0gave talks about \u201cModelling the aging of the heart” and the \u201cGuiding ablation from EGM characteristics”, respectively.<\/p>\n
