Paradoxical Left-to-Right Device Embolization Complicating Transcatheter Mitral Valve Edge-to-Edge Repair.

ABSTRACT

We describe an unusual presentation of transcatheter mitral valve edge-to-edge repair device embolization into the left common femoral vein in a patient with primary degenerative mitral regurgitation. We hypothesize a possible mechanism for this phenomenon, factors that may increase the risk of this complication, and outline the patient's clinical course. (Level of Difficulty Intermediate.).
