Heart valves, digitized--part II

Warning: Some of the images referred to in this post are not for the faint of heart. If you don't like watching operations on TV or feel faint at the sight of blood, you may want to forgo checking out the images of the valves during or post-implantation.

As I promised to you all in an earlier post, the complete collection of images from the Jeri Dobbs artificial heart valve collection is now available for viewing in the OHSU Digital Resources Library.
A search (All of the words) on "Jeri Dobbs" will retrieve all 71 images from this collection, which also contains twenty-seven actual Starr-Edwards valves, a Kay-Shiley valve, and a pig valve.

The digitized images include photographs of artificial valve models of various types, as well as x-rays of patients with artificial valves, examples of the wear on valve components after periods of implantation, diagrams of testing equipment developed by Lowell Edwards and Edwards Laboratories, and images of the cardiac pacemaker developed by Albert Starr.

Another great resource for charting the development of artificial heart valves is the Bakken Artifacts Database section on blood circulation.
