Why the study?
What are the echocardiographic mechanisms underlying functional atrial mitral regurgitation in persistent atrial fibrillation?
What are the echocardiographic mechanisms underlying functional atrial mitral regurgitation in persistent atrial fibrillation?
Functional atrial mitral regurgitation in persistent atrial fibrillation is multifactorial, involving mitral annulus dilatation, contractile dysfunction, loss of saddle shape, and posterior mitral leaflet tethering.
