Key result
Left atrial fractional shortening (LAFS) correlated with peak atrial longitudinal strain (PALS) (P<0.05) and can serve as a surrogate using the formula PALS = 21.07 + 0.364x(LAFS).

LAFS may enable PALS estimation without speckle tracking; leaves open prospective validation before clinical adoption.

Does left atrial fractional shortening (LAFS) correlate with peak atrial longitudinal strain (PALS) and left atrial emptying fraction in patients undergoing transthoracic echocardiography?
Left atrial fractional shortening is a simple, feasible echocardiographic measurement that correlates with peak atrial longitudinal strain and can serve as a practical surrogate when speckle-tracking is unavailable.
p-value: p=< 0.05
Mandoli et al. (2019) conducted an observational in Patients undergoing transthoracic echocardiography (n=153). Left atrial fractional shortening (LAFS) vs. Peak atrial longitudinal strain (PALS) was evaluated on Correlation of LAFS with peak atrial longitudinal strain (PALS) and LA emptying fraction (EF) (p=< 0.05). Left atrial fractional shortening (LAFS) correlated with peak atrial longitudinal strain (PALS) (P<0.05) and can serve as a surrogate using the formula PALS = 21.07 + 0.364x(LAFS).
