Left atrial strain in mitral valve disease: a comparative analysis of regurgitation and stenosis

This study elucidates the distinct impacts of mitral stenosis and regurgitation on left atrial function, as reflected by LA strain parameters. LAstrainCD emerges as a key discriminator between these conditions, highlighting differences in atrial remodeling due to pressure and volume overload. Furthermore, LAstrainCT's correlation with MR severity enhances our understanding of atrial adaptation to regurgitant volume. These findings advance the knowledge of mitral valve disease pathophysiology, providing a foundation for improved diagnostic and therapeutic strategies.
