Abstract
Mitral Insufficiency (MI) is currently the second most common cause of valvular disease accounting for one-third of valvulopathies. The early
detection of deteriorating systolic function in patients with chronic mitral regurgitation, and thus the ability to identify the most appropriate
moment for surgery remains a challenge to physicians. The analysis of myocardial deformation has recently emerged as a quantitative means
of reliably estimating myocardial contractility. In the assessment of left ventricular function it is therefore less dependent on the load than
traditional methods. There are currently two ways to assess myocardial deformation: tissue Doppler (TD) and a new method known as speckletracking
(ST). The aim of the present revision was to deepen the study of the longitudinal myocardial deformation of the left ventricle using
these techniques for predicting the LVEF deterioration in patients who have undergone surgery for chronic severe mitral valve regurgitation
