It was reported that on 02 nov.2023, a 28mm amplatzer amulet left atrial appendage (laa) occluder was chosen for implantation utilizing a 14f amulet delivery sheath.Before the amulet procedure, a mitraclip was placed successfully.The 28mm amulet was advanced to the laa, where transesophageal echocardiogram (tee) imaging showed that the device was undersized.The 28mm was removed and replaced with a 31mm amplatzer amulet laa occluder.The delivery system was not replaced as per instructions for use, to maintain access.Following the 31mm amulet partial deployment (ball position), a thrombus was suspected on tee.A small fiber-like filament was observed and seemed to be attached to the device (lobe) during the ball position step.The amulet device and the delivery system were then retrieved from the patient which removed the object.At that moment, patient's activated clotting time (act) was 309.The physician went ahead with a second amulet 31mm and replacement delivery system and the device was deployed and successfully released.The sheath was in the patient for a longer period due to device recaptures, repositioning and mis-sizing.The patient was given 100 units/kilogram heparin during the procedure and act was tested regularly.There was no clinically significant delay.The patient remained hemodynamically stable throughout the procedure and is recovering.
