Using mathematical modeling and computer simulation, USP researchers tested improvements in the development of a Wheatley aortic valve before prototypes, saving time and resources.

This note updates the mathematical model published in the Journal of Biomechanical Engineering by McKee et al. [McKee, S., Cuminato, J. A., Stewart, I. W., and Wheatley, D. J., 2021, “A Mathematical Representation of the Wheatley Heart Valve,” ASME J. Biomech. Eng., 143(8), p. 081006].

This note extends previous work of the authors modelling the Wheatley valve by using six intersecting and contiguous ellipses to obtain a generalised mathematical representation of the Wheatley valve.

British Heart Foundation’s Professor Jeremy Pearson spoke to Professor David Wheatley in the summer of 2021 for the next episode of his 'In Conversation With...' series.

Published in the Journal of Biomechanical Engineering, this research article shows a set of intersecting and contiguous circles whose perimeter, upon extending appropriately to three dimensions, can be seen to be a natural mathematical representation of the Wheatley Heart valve.

This article charts the development history of the Wheatley valve and details the three methods used to form the polymer leaflets - dip moulding, injection moulding and folding flat sheets.

This article reviews the state of knowledge about fluid dynamics in the thoracic aorta and confirms the basis for anticipating a synergistic relationship of our novel valve design with known ascending aortic blood flow patterns.
