Dynamic Changes in Myocardial Function Early and Long-Term After Mitral Valve Surgery Detected by Speckle-Tracking Echocardiography
Background: It is known that mitral valve surgery produces an early reduction in hemodynamic overload after the procedure. However, the reduction in left ventricular (LV) ejection fraction (EF) may persist over the long term. Speckle-tracking echocardiography (STE) provides more sensitive indices of cardiac performance...
