PALS may correlate with TEE parameters in persistent AF; leaves open its clinical utility pending prospective validation.
Does global peak atrial longitudinal strain (PALS) predict reduced LAA emptying velocity and/or thrombus in patients with persistent non-valvular atrial fibrillation?
Global peak atrial longitudinal strain (PALS) measured by transthoracic echocardiography is a strong predictor of left atrial appendage thrombus or reduced emptying velocity, potentially offering a non-invasive alternative to TEE for thromboembolic risk assessment in AF.
