Griguer AR, et al. - In this present study, the authors assessed and compared the prognostic value of acceleration time (AT) and the ratio of AT to ejection time (ET) in patients with aortic stenosis (AS). During follow-up, AT/ET was strongly correlated with excess risk for death among ejection dynamics parameters in patients with AS. In clinical practice, AT/ET ought to be considered in the multiparametric echocardiographic prognostic assessment of patients with AS.
