Brief Summary

AthenaValve aims to develop and initial validate a novel serum diagnostic kit, for the assessment of severity and prognosis of progression of aortic valve stenosis (AS, a devastating disease without e...

Detailed Description

The deposition of calcium salts in the arterial wall and the heart valves is a commonly occurring phenomenon associated with increasing age and various pathological factors. A particular case is the c...

Eligibility Criteria

Inclusion

  • Retrospective cohort: patients with severe aortic valve stenosis in echocardiography:
