Evaluation of Left Atrial Size and Function: Relevance for Clinical Practice

•The LA is emerging as a biomarker for evaluation of diastolic dysfunction, AF, and HFpEF. •LA size, although routinely evaluated by 2DE, may be more accurately evaluated by 3DE. •LA function is important and may demonstrate alterations prior to changes in LA volume. •Both volumetric and strain analysis can be performed to evaluate LA phasic function. •Noninvasive evaluation of LA pressure is emerging as an important modality. Left atrial (LA)...
