Research in the present study involves the development of an interatrial shunt. The shunt includes a proximal end attached to a disc for supporting a septal wall on the right atrium side, a distal end attached to a flat disc to support the septal wall on the left atrium side, and an intermediate portion connecting the proximal and distal ends that includes a neck portion for providing passage between the left and right atrium of the septal wall. In the proximal, distal and middle portions, the dimensions are selected to provide a low crimp profile ranging from 2-3 mm. Interatrial shunt devices with a unique mechanism to directly reduce left atrial pressures, improve exercise tolerance and potentially improve clinical outcomes and heart failure. As the implant includes the three design such as curvature and flat disc, an implant with barbs and flat disc and an implant with flair and flat disc. The implant with flair and flat disc is flexible to use and easily movable for the implantation.
