May support LAS change as predictor of sinus rhythm maintenance after cardioversion; hypothesis-generating and requires prospective validation before clinical use.
Does the change in left atrial strain or stiffness index after cardioversion predict the maintenance of sinus rhythm in patients with persistent atrial fibrillation?
An increase in left atrial strain immediately after cardioversion may serve as a useful echocardiographic predictor for the maintenance of sinus rhythm in patients with persistent atrial fibrillation.
Shaikh et al. (2012) studied this question.
