Usefulness of the echocardiographic velocity ratio for detection of significant aortic stenosis.
American Journal of Cardiology
Journal Article --- Old month value: Nov 1
In this study, which included 56 patients with aortic stenosis, the predictive value of the fractional shortening velocity ratio was evaluated. This Doppler index allowed detection of significant aortic stenosis (0.53 cm2/m2), with a positive predictive value of 93% and a negative predictive value of 92% for a cutoff value of 0.8.
