NCT03305536

Brief Summary

Aortic Stenosis is a common but fatal disease when it becomes symptomatic, specially if not treated. Until now surgery remains the only reliable and effective treatment. In this study, the investigators will examine the effect of high dose of Menaquinone-7 (MK-7) supplementation (1000 mcg)/day on the progression of the aortic valve disease. The investigators hypothesize that MK-7 supplementation may slow or even reverse the progression of the disease process.

Outcome Measures

Primary Outcomes (3)

  • Evolution of the Aortic Valve Hemodynamic measured by echography: Change in Gradients in (mm Hg)

    3 years

  • Evolution of the Aortic Valve Hemodynamic measured by echography: Change in Surface area in (cm2/m2)

    3 years

  • Evolution of the Aortic Valve Hemodynamic measured by echography: Change in V max in (m/sec)

    3 years

Secondary Outcomes (4)

  • Activation of the MGP measured by the dp-uc MGP level which is a marker of vascular calcification.

    3 years

  • Reduction of the Aortic Valve calcification measured by CT Scan

    3 years

  • Improvement of dyspnea (at rest and effort)

    3 years

  • Improvement of the quality of life of the patients

    3 years

Study Arms (2)

Interventional

ACTIVE COMPARATOR

1000 mcg/day of Vitamin K2 + 5000 IU/day Vitamin D3 as a treatment to decalcifiy the valve

Dietary Supplement: Vitamin K2 (Menaquinone 7) + Vitamin D3

interventional

ACTIVE COMPARATOR

5000 IU/day of Vitamin D3 will be given to measure the progression of the disease along the time of the study

Dietary Supplement: Vitamin K2 (Menaquinone 7) + Vitamin D3

Interventions

Vitamin K2 + Vitamin D3 arm will be compared with Vitamin D3 arm to slow of reverse the progression of the disease
