Mechanisms of Excess Risk in Aortic Stenosis

Cardiac MRI scan pre- and post- aortic valve replacement to assess degree of left ventricular remodelling, fibrosis and myocardial blood flow.

Blood tests looking evidence of cardiac structural remodelling and function.

Determine post-AVR arrhythmia burden

Validated assessment of functional capacity - distance walked over 6 minute time frame.

Ultrasound assessment of heart structure and function. Standard of care in valve surgery pathway.
