The last one and a half-decade was the era of myocardial strain imaging by speckle tracking strain echocardiography (STE) and various authors confirmed its accuracy. However, the measurements are mostly confined to the left ventricular (LV) global longitudinal strain (GLS).1,2 Though LA function has been a subject study in the past decades and interesting pathophysiological findings have been described in the literature, not many of them have been translated into clinical practice. Commonly used approaches to study LA function are Doppler and volumetric approaches which do not bring forth the entire information about LA function. However, a deformation study by STE provides a window on all phases of LA function (LA as a reservoir, conduit, and booster pump).3
