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 COMPARATOR1000 mcg/day of Vitamin K2 + 5000 IU/day Vitamin D3 as a treatment to decalcifiy the valve
interventional
ACTIVE COMPARATOR5000 IU/day of Vitamin D3 will be given to measure the progression of the disease along the time of the study
Interventions
Vitamin K2 + Vitamin D3 arm will be compared with Vitamin D3 arm to slow of reverse the progression of the disease
