The aim of this pilot study is to assess function, independence, frailty and emotional status in 30 patients who have been accepted for TAVI. All patients will attend clinic for review at 4 weeks post implant and at that stage, 15 patients will be randomised to undertake a cardiac rehabilitation programme and the remaining 15 patients will receive standard of care. All patients will return to clinic at 3 months and 6 months post implant and undertake the functional, independence, frailty and emotional testing again.
