Brief Summary

The aortic valve is the main outlet valve from the heart. This valve can become diseased and narrowed when it needs to be replaced with an artificial valve. Currently, this is the commonest reason for someone to undergo a heart valve operation in the UK. Unfortunately, there are no medical treatments that can prevent or delay the progression of this disease process. Here, the investigators propose to use new state-of-the-art imaging techniques to better understand the disease process so that the investigators can effectively design and assess potential new treatments. The ultimate aim is to stop this disease before patients need to have surgery. In addition the investigators believe this technique will allow us to predict the rate of progression of the disease

Outcome Measures

Primary Outcomes (1)

  • Aortic Valve Peak Velocity

    We beleive NaF and FDG uptake in the valve will predict rate of progression of the disease. Disease severity will be measured by the aortic valve peak velocity

Biospecimen

Retention: SAMPLES WITH DNA

In patients undergoing aortic valve replacement during the course of the trial we will retain samples of their aortic valve for histological studies.
