Atrial fibrillation is characterized by structural remodeling of the atrial myocardium—a slow process that comprises morphological changes that affect atrial myocardial architecture and atrial ultrastructure. Here Corradi et al. examine the morphological changes that characterize the fibrillating atrial myocardium at histological and ultrastructural levels, and explore how the pathogenetic mechanisms involved in AF could lead to new treatments.
