AI Article Synopsis
- The assessment of left atrial (LA) function is crucial for understanding heart performance, particularly its impact on left ventricular (LV) function in various cardiovascular diseases.
- Non-invasive methods like transthoracic 2D echocardiography and Doppler can measure LA function, but 2D speckle tracking echocardiography (STE) offers a newer way to evaluate LA mechanics.
- The review emphasizes the need for standardized techniques to assess LA phasic functions using STE and discusses recent findings on its clinical applications, noting ongoing challenges in consistent data due to methodological issues.
Article Abstract
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.
