Regional left ventricular strain recovery after percutaneous mitral balloon valvuloplasty: determinants and prognostic implications.
In severe rheumatic mitral stenosis (MS), left ventricular (LV) systolic function is often considered preserved based on ejection fraction. However, longitudinal myocardial mechanics may be impaired and may improve after relief of inflow obstruction. The regional pattern of strain recovery following percutaneous mitral...
