    Hypothesis and Background: A high prevalence of downwardly sloping type 3 Aortic Arch (AA) in elderly humans with Left Ventricular Hypertrophy (LVH) led us to hypothesize that Major Aortic Arch Branches (MAAB) acting through the AA and ascending Aorta are pivotal in subtending the heart in its anatomic position. Based on established commonality in comparative anatomy of terrestrial mammals we tested our hypothesis in the even-toed ungulate model. Methods and Results: We observed 5 animals (2 sheep and 3 goats) at a licensed abattoir as they were being dressed, in a requested order. In vertical orientation, midline incision bisecting the entire chest and anterior abdominal wall was made and after retracting the ribs the heart was visualized. In stepwise fashion: abdominal organs, diaphragm, lungs and Vertebropericardial Ligaments (VPL) were remo.. View More»
