NCT05696145

Brief Summary

The goal of this study is to investigate the genetic and gender specific differences, in patients with low flow low gradient aortic stenosis and high flow high gradient aortic stenosis. Patients referred for surgical aorticvalve replacement will be offered to participarte in the study. The main questions the study aims to answer are:

  • Cardiac ultrasound, MR- and CT-scan prior to surgery
  • Blooddraw prior to surgery.
  • Heartmuscle biopsy during surgery
  • Cardiac MR-scan 1 year after surgery.

Study Population

Patients referred for surgical aortic valve replacement at the department of Cardiothoracic and vascular surgery at Odense University Hospital, Denmark will be evaluated and if they meet the inclusion criteria they will be invited to participate in the study.

You may qualify if:

  • Severe AS (estimated by the local heart team, aortic valve area\<1cm2) referred for AVR at the cardiology department at Odense University Hospital
  • Age \> 18 years
  • Signed informed consent

You may not qualify if:

  • Bicuspid aortic valve.
  • LV systolic dysfunction (LVEF\<50%).
  • Patients with concomitant moderate-severe aortic valve regurgitation.
  • Concomitant moderate-severe mitral valve regurgitation.
  • Moderate to severe nephropathy (s-creatinine \>200 mmol/l)
  • Unwilling to participate in the study.
  • Claustrophobia.
  • Permanent cardiac devices (pacemaker and ICD)
