The themes remain the testing of replacement valves and the optimisation of timing for native valve surgery, the interaction of LV, aortic valve and aortic physiology in aortic stenosis.

John Chambers and Divaka Perera are jointly supervising Matt Lumley s PhD in interactions between LV, valve and aortic physiology and coronary flow

Bernard Prendergast and Simon Redwood supervise Hannah McConkey s thesis investigating the pathophysiology of low flow, low gradient aortic stenosis.

Current studies include:

Rimington H, Parkin D, Chambers J, Blauth C. A randomized comparison of the Toronto Stentless and Baxter Pericardial valve.
Rimington H, Parkin D, Hayes A, Chambers J. Audit of sonographer/nurse-led valve clinic
