Why the study?
It was hypothesised that LA fibrosis identified by low-voltage areas may influence the mechanical and electrical function of the LAA and RAA in long-standing persistent AF.
Do left and right atrial appendage functional features predict voltage-defined left atrial remodeling in patients with long-standing persistent atrial fibrillation?
Do left and right atrial appendage functional features predict voltage-defined left atrial remodeling in patients with long-standing persistent atrial fibrillation?
Left and right atrial appendage functional parameters, specifically AF cycle length and emptying velocity, can predict advanced stages and regional distribution of left atrial fibrosis in patients with long-standing persistent AF.

LAA/RAA dysfunction was associated with LA low-voltage areas in LSPAF; hypothesis-generating for fibrosis assessment via echocardiography.
