Acute Improvement in Myocardial Function Assessed by Myocardial Strain and Strain Rate After Aortic Valve Replacement for Aortic Stenosis

Strain and strain rate parameters seemed to relate to LV function and aortic stenosis severity. Further, they seemed to be superior to tissue velocity and conventional echocardiography in detecting subtle changes in myocardial function after AVR before LV mass and LV function showed improvement.
