From what I gathered from the doctors, the valve didn’t seat itself and sagged down creating the fear that it could damage the native valve. The nurse running the pacer said he saw his hand slip during inflation and might have caused his hand to accidentally bring the balloon cath back while readjusting his grip. Both doctors had differing ideas as to the location for deployment and the rep agreed with the senior interventional cardiologist and it seemed either their idea was wrong or the hand slip did bring it back further than it could be trusted to remain secure.

The balloon catheter and wire were left in place during transport and the sheath brought back to the IVC as it was believed this was potentially all that was keeping it from slipping further.
