Strain imaging to assess early effects of successful percutaneous balloon mitral valvotomy on left atrium mechanics.

ABSTRACT:

Background

Global left atrial strain (LA) has been used as a novel assessment tool to evaluate left atrial function. However, not much has been investigated to study the effect of percutaneous balloon mitral valvotomy (BMV) in patients with rheumatic severe mitral stenosis on global LA strain. We studied the relationship between global left atrial (LA) strain and severe mitral stenosis and the effect of BMV on LA strain.

Results

A total of 29 patients satisfying the criteria for severe mitral stenosis underwent balloon mitral valvotomy (67% females; mean age, 39.53 ± 11.78 years). Global left atrial strain was assessed by speckle tracking echocardiography before and after valvuloplasty. Global LA strain was impaired in patients with severe mitral stenosis and improved 24-48
