Left atrial strain and strain rate before and following restrictive annuloplasty for ischaemic mitral regurgitation evaluated by two-dimensional speckle tracking echocardiography

Abstract

Left atrial peak global strain, peak systolic SR, and peak early diastolic SR were cofactors associated to recurrent MR. The assessment of LA strain and SR, in addition to other echocardiographic parameters, can be helpful in detecting patients undergoing UMRA who are unlikely to benefit from annuloplasty.
