Left Atrial Embolization During Transcatheter Mitral Valve in Mitral Annular Calcification: Successful Percutaneous Bailout Using an Atrial Septal Defect Occluder.

ABSTRACT:

Objective

To describe a percutaneous rescue maneuver for a left atrial embolization during transcatheter mitral valve replacement where an atrial septal defect (ASD) occluder secures the embolized valve to the interatrial septum.

Key steps

Key steps include using a double wire, oversizing the ASD occluder, and deploying it in a Hershey kiss configuration.

Potential pitfalls

Loss of wire position, undersizing the ASD occluder, and deploying with a traditional disc configuration.

Take-home message

If a transcatheter valve embolizes into the left atrium during transcatheter mitral valve replacement and remains on the wire, an ASD occluder can be used in a bailout fashion to secure the embolized valve to the interatrial septum.
