Twenty-two patients with aortic stenosis (AS) underwent conventional Doppler echocardiography and automated segmental motion analysis (ASMA) of the left ventricle to evaluate the value of the latter technique in the diagnosis of severe AS. An index was calculated by dividing time from the R-wave by maximum area change between the RR interval. Sensitivity, specificity, positive and negative predictive values and overall accuracy for the ASMA index >0.40 were 100, 91.7, 92.3, 100 and 95.8%, respectively.
