A 3-D printout of a perfusion-fixed human heart examined in the Visible Heart Laboratory. It was created by performing a 3-Tesla
MRI scan of the specimen and then creating a digital model of the heart using Mimics software.
3-D representations of the coronary arteries and veins of perfusion-fixed human hearts that were scanned by
contrast-computed tomography and reconstructed using modeling software. The first heart is normal; the others are diseased.
Paul Iaizzo, Ph.D., performing in situ studies on a reanimated swine heart in the
Visible Heart Laboratory in the Mayo Building on the University of Minnesota campus.
The Visible Heart Lab has reanimated hundreds of swine hearts, like this one, using a clear,
artificial blood that lets tiny vidoescopes record the heart’s functional anatomy.
Dr. Iaizzo uses the Visible Heart Lab’s collection of 3-D models and plastinized human and large mammalian hearts for educational demonstrations.
