Abstract

The HELEX device is approved for percutaneous closure of an atrial septal defect (ASD). It is also often used off-label to close patent foramen ovale (PFO). The device is well tolerated because it is very flexible, but this characteristic increases the likelihood of embolization of locked implants. While the company provides a mechanism to retrieve devices that do not lock correctly, retrieval of locked and released devices is much more difficult. A case of percutaneous retrieval of an embolized, locked HELEX device is reported. This device was successfully retrieved from the aorta by snaring the left atrial eyelet and unlocking the device. A variety of potential techniques for retrieval of these devices was explored on the bench top. Strategies which can be used to successfully retrieve embolized HELEX devices are described.
