Prognostic value of left atrial reservoir function in patients with severe aortic stenosis: a 2D speckle-tracking echocardiographic study

Conclusion
In patients with severe AS, a global PLAS <21% is an independent predictor of prognosis. Given the combined influence of LV diastolic and systolic function and of LA performance on sPAP, the decline of PLAS might be considered a marker of global myocardial impairment in AS. Further studies are needed to confirm the critical role of LA relaxation in prognosis and to validate its relevance in routine clinical practice.
