Hemi-balloon dislodgement during a percutaneous balloon pericardial window procedure: removal using a second pericardial catheter.

We describe retrieval of a balloon fragment from the pericardial space during a percutaneous balloon pericardial window procedure. A second pericardial catheter was placed, and the transfer wire was snared. The second catheter was then used to push the balloon fragment back through the pericardium and out to the skin.
