Electron beam computed tomography for the quantification of aortic valvular calcification.

摘要: BACKGROUND AND AIM OF THE STUDY Calcific aortic stenosis is common in the elderly; indeed, 30-60% of patients with mild 'senile' will progress to severe obstruction. Nonetheless, predictors progression are incompletely defined, and non-invasive technologies capable quantifying valve calcium needed. The reliability electron beam computed tomography (EBCT) was evaluated for quantification content. METHODS Nineteen without restrictive calcification underwent EBCT scanning. Separate scores, 30 s apart, were obtained all patients, Spearman correlation coefficient calculated between measurements. relationship dichotomized mean score area also investigated. RESULTS There excellent scores (R = 0.99, p 0.0001), as well a significant inverse upper lower ranges (p 0.002). CONCLUSION can be used reproducible quantitation calcification. While at their extremes, inversely related area, further evaluation needed define precise nature this throughout spectrum severity. holds promise longitudinal assessment valvular its response potential medical therapies.
