Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.
