Evaluation of an Implant Free Interatrial Shunt to Improve Heart Failure

The InterShunt PAS-C System is a transcatheter system that creates a shunt by excising tissue from the interatrial septum resulting in a left to right atrial shunt that off-loads elevated left atrial pressure, potentially reducing symptoms and improving quality of life. The PAS-C System does not require a permanent implant to maintain patency of the interatrial shunt.
