Does echocardiographic assessment of left atrial strain and strain rate correlate with LA wall fibrosis and AF burden in patients with paroxysmal and persistent atrial fibrillation?
Echocardiographic assessment of LA strain and strain rate correlates with MRI-detected fibrosis and AF burden, offering a quick and feasible tool for evaluating structural remodeling in AF.
LA wall fibrosis by delayed-enhancement MRI is inversely related to LA strain and strain rate, and these are related to the AF burden. Echocardiographic assessment of LA structural and functional remodeling is quick and feasible and may be helpful in predicting outcomes in AF.
