The guessing game of where to put a stent as patients undergo heart surgery may soon be over. Researchers from the Georgia Institute of Technology and the Piedmont Heart Institute have discovered a new way to develop heart valve models, by using a 3D printer to make models specifically for each patient undergoing valve replacement surgery. Doctors currently take a CT image to see the condition of the heart, and then select the stent and location they feel is best. However, they have to select from several options of sizes and brands, which can lead to fitting problems.
