Real Hearts, Remarkable Images
If you've ever wanted to see the heart from within, you must see the work of Paul A. Iaizzo, PhD from the University of Minnesota. On this website are images obtained from actual human hearts removed before organ donation and bathed with perfusate and nutrients in Dr. Iaizzo's lab, permitting the heart to continue beating approximately 4-5 hours after it was removed to obtain these incredible images using tiny fiberoptic cameras placed within the heart chambers. His work was supported by a grant from Medtronic, Inc.
