Myocardial infarction can induce mitral regurgitation through the displacement of the papillary muscles by 2.5-5mm, leading to pulmonary hypertension, atrial fibrillation, and heart failure. MQP GRG 1601 designed a cantilever papillary muscle repositioning device for the elimination of mitral regurgitation. Insertion occurred through port access surgery, where the muscles would be maneuvered to a position that would allow for proper closure of the mitral valve leaflets. This was tested through simulations, force effect diagrams, and in vitro experiments.
