Relationship between LA peak systolic strain and LAA eV in all patients. LA peak systolic strain was significantly correlated with LAA eV (R = 0.693, P < 0.0001) (A). Relationship between LA peak systolic strain and LAA eV in patients with sinus rhythm (B), paroxysmal AF (C), or chronic AF (D). LAA, left atrial appendage; eV, LAA emptying flow velocity; AF, atrial fibrillation.
