Consequently, research in this field is required. While somewhat controversial, especially if not done right, the use of animals for research and training purposes remains a mandatory step of translational research. Small animal models have contributed considerably to unraveling the cellular and molecular mechanisms of CVDs, but extrapolation to a clinical scenario is hindered by the remarkable cardiovascular dissimilarities with humans 2 , 3 . Hence there is importance in large animal models, as they are closer to humans with respect to size as well as anatomical and physiological features 3 , 4 .
