NCT04359030

Brief Summary

The aim of this study is to evaluate the rate and anatomy of the aortic wall and leaflet calcification of the FS prosthesis implanted as full root in patients younger than 60 years compared to a stented bioprostheses (Perimount Magna Ease, PM). A 3D CT scan will be used to assess the calcification score and to determine the relationship between calcification and aortic valve leaflet.

Outcome Measures

Primary Outcomes (1)

  • Quantification of aortic leaflet Calcium-score in FS and PM valve

    The Agatston score. The score is calculated using a weighted value assigned to the highest density of calcification in a given coronary artery. The density is measured in Hounsfield units (HU), and score of 1 for 130-199 HU, 2 for 200-299 HU, 3 for 300-399 HU, and 4 for 400 HU and greater. The higher the score the more the calcification.

    3 years

Secondary Outcomes (4)

  • Echocardiographic function of the aortic valve at rest and during exercise: transvalvular mean and peak gradient

    3 years

  • Echocardiographic function of the aortic valve at rest and during exercise: Valve regurgitation

    3 years

  • Exercise capacity: New York Heart Association class

    3 years

  • Exercise capacity: maximum oxygen consumption

    3 years
