Trial Summary

What is the purpose of this trial?This trial is testing a new device to help patients with heart problems by creating a small passageway between the upper chambers of their heart. This can make it easier for blood to flow and reduce the heart's workload. Since the initial description of a device for heart issues in the mid-1970s by King and Mills, a number of devices have been developed.
