Abstract
Introduction :LAmbre device
was rarely reported to get dislocated during the procedure and it can be
deliberately recaptured, completely retrieved and re-deployed.A LAmbre
device trapped in the mitral valve is infrequent and which can hardly be
recaptured by percutaneous retrieval.
Methods :We reported a planted LAmbre device(Lifetech
Scientific Corp.) that was dislocated during the procedure of Left
Atrial Appendage Occlusion.The patient’s hemodynamic parameters suddenly
changed while we withdrew the delivery sheath.The fluoroscopy and TEE
showed that the device was detached from the landing zone and closed to
the mitral valve.
Result :We attempted
percutaneous retrieval but failed and the device was subsequently
recapatured by a cardiovascular surgery.
Conclusion :We should make
sure the occluder in the optimal position and operate prudently to avoid
device migration or detachment.If the device locates in the mitral valve
or LV and causes hemodynamic changes,a surgery should be performed as
quickly as possible to retrieve the implant.
