摘要

Recent data have shown that in severe aortic stenosis (sAS), LVEF >60% predicts further deterioration of LVEF (EF) and is a risk factor for poor outcome. We hypothesized that in sAS, systolic function is better understood by investigating midwall stress-shortening (FSmw) rather than EF in patients
