We also demonstrated incremental diagnostic value of LA STE measurements over established risk stratification scale in identifying patients with LAAT. Previously it was established that LS measured in 4CH and 2CH views (without roof segments) has additional value over CHA 2 DS 2 -VASc Score, but for the risk stratification of embolism in patients with AF (20). The **data** considering the additional value of LA strain rate are unavailable so far. Furthermore, our model of LA consisted of 12 segments.
