Why the study?
Single leaflet device attachment and device embolization appear as potential risks following the MitraClip procedure that have yet to be clarified.
Clip instability during the MitraClip procedure, particularly in patients with severe degenerative mitral regurgitation such as Barlow syndrome, can lead to late device embolization requiring emergency surgical intervention.
Late embolization after MitraClip in Barlow syndrome warrants caution; hypothesis-generating for device stability and surveillance in degenerative MR.
Objective: MitraClip is currently indicated for symptomatic severe mitral regurgitation (MR) in surgical high-risk patients. After the MitraClip procedure, single leaflet device attachment and device embolization appear as potential risks that have yet to be clarified. We present a case with occult single leaflet device attachment followed by late device embolization.
