DOI: 10.1016/j.ijcard.2020.01.042
Abstract: BACKGROUND Left atrial (LA) sphericity has been proposed as a more sensitive marker of atrial fibrillation (AF)-associated atrial remodeling compared to traditional markers such as LA size. However, mechanisms that underlie changes in LA sphericity… read more here.
