| Research Abstract |
We constructed the computer model of human atria, and conducted simulations (in silico) of chronic atrial fibrillation (AF). Then we found that fibroblast proliferation promotes AF chronicity and forms complex fractionated atrial electrogram (CFAE), known as the effective ablation target for chronic AF (Fibroblast-CFAE hypothesis). Our findings could contribute to better understanding of the mechanisms underlying CFAE-targeted AF ablation, and will improve the outcome of refractory chronic AF ablation.
