This paper suggests a new model, for prosthetic heart valve implantation surgery using shape memory alloy (SMA), as the solution to the current existing limitations. It is true that prosthetic heart valve technology improved significantly since its first introduction in the 1950s. Nevertheless, the surgery is invasive because it requires opening one's heart. This not only increases the risk of the surgery itself, but restrains the elderly from receiving such surgical procedures. The research is divided into three sections. Researchers begin by introducing the current procedure of prosthetic heart valve implantation, and conduct a comparative analysis of SMA. Second, the limitations that exist in the current status quo of implantation surgery, are examined. Third, based on the comparative analysis of SMA, researchers suggest a new model of conducting a prosthetic heart valve surgery, and elaborate on future expectations. As this study is approaching the matter theoretically, further discussion is needed on the issue of practicality and feasibility in application.
