[Dislodgement of a left atrial appendage occluder : Step-by-step management by retrograde extraction with a "home-made snare" and two sheaths].

Dislodgement of a left atrial appendage occluder after liberation represents a nightmare in cardiac interventions. We present a case with this complication and an easy step-by-step protocol that can help to retrieve and venously extract this foreign body with less stress. Particularly the do-it-yourself construction of a "home-made snare" facilitates trapping of large implants which are too large for conventional snares.
