Why the study?
Does the iatrogenic atrial septal defect after MitraClip implantation induce a relevant interatrial shunt or right ventricular overload?
Does the iatrogenic atrial septal defect after MitraClip implantation induce a relevant interatrial shunt or right ventricular overload?
The iatrogenic atrial septal defect created during MitraClip implantation does not cause relevant interatrial shunting or right ventricular overload, and may potentially offer beneficial left atrial pressure relief.

Supports procedural safety on shunting and RV load; leaves open potential LA decompression benefit.
