Plastination is a technique used to preserve organs and tissues in which the water and fat are replaced by plastic materials, yielding specimens that do not decay and retain most properties of the original sample.

This plastinated heart is one example from the comprehensive suite of Surgical Training and Pathology Services offered by IMMR’s in-house team of veterinary cardiac surgical specialists and Board-certified Veterinary Pathologists, in collaboration with the veterinary school of Maisons-Alfort, Paris.
