What are the methodological gaps and clinical applications of 2D speckle tracking echocardiography for assessing left atrial function?
Standardization of 2D speckle tracking echocardiography is needed to reliably assess left atrial function and establish consistent normal ranges and diagnostic cut-offs.

Standardization of 2D speckle tracking is required before clinical use; leaves open consistent normal ranges and cut-offs for left atrial assessment.
The assessment of left atrial (LA) function is used in various cardiovascular diseases. LA plays a complementary role in cardiac performance by modulating left ventricular (LV) function. Transthoracic two-dimensional (2D) phasic volumes and Doppler echocardiography can measure LA function non‑invasively. However, evaluation of LA deformation derived from 2D speckle tracking echocardiography (STE) is a new feasible and promising approach for assessment of LA mechanics. These parameters are able to detect subclinical LA dysfunction in different pathological condition. Normal ranges for LA deformation and cut-off values to diagnose LA dysfunction with different diseases have been reported, but data are still conflicting, probably because of some methodological and technical issues. This review highlights the importance of an unique standardized technique to assess the LA phasic functions by STE, and discusses recent studies on the most important clinical applications of this technique.
