["Function-corrected" indexes for precise estimation of aortic stenosis severety].

: The aim of the research was to study clinical significance of "function-corrected" indexes (FCI) in non-invasive evaluation of aortic valvular stenosis (AVS) severity. 85 patients with degenerative aortic valve calcification (42 - with AVS and 43 - without aortic ostium (AO) stenosis) were subjects of a cross-sectional study. Significant correlation between AO area and FCI indexes was demonstrated. When it is not possible to determine AO by planimetric methods, it may be counted using FCI with good sensitivity (87%) and specificity (94%).
