Left Atrial Reservoir Strain To Identify Advanced Atrial Cardiomyopathy in Patients With Atrial Fibrillation.
BACKGROUND Left atrial reservoir strain (LASr) is a novel marker of left atrial (LA) function. We hypothesized that LASr can be used to identify atrial cardiomyopathy in patients with atrial fibrillation (AF). OBJECTIVE To evaluate the association between LASr and invasive and non-invasive markers of atrial cardiomyo...
