Abstract:
To date, this is the first description of a spontaneous unscrewing of an Amplatzer Amulet device from its delivery cable while its lobe was partially deployed within the left atrial appendage. In such cases, the device should be pushed forward to complete the deployment and to rescrew the device to the DC in order to prevent an unavoidable cardiac surgery.
