Key result
Open surgical removal of migrated WATCHMAN with modified maze restores sinus rhythm at 2 months.
Why the study?
The WATCHMAN atrial appendage closure device carries small risks of procedural complications, including device migration, embolization, or pericardial effusion.

WATCHMAN migration may require open surgical retrieval with maze in select cases; this report leaves open incidence, prevention, and generalizability.
The WATCHMAN™ atrial appendage closure device is designed to reduce the risk of stroke in patients with nonvalvular atrial fibrillation who are not suitable candidates for long-term oral anticoagulation therapy. However, the device also carries small risks, including procedural complications such as device migration, embolization, or pericardial effusion. We describe a case of WATCHMAN device migration requiring surgical retrieval.

Saleeb et al. (2024) conducted a case report in Migrated WATCHMAN device in nonvalvular atrial fibrillation (n=1). Open surgical removal of WATCHMAN device and modified maze procedure was evaluated on Successful device extraction and clinical recovery. Open surgical removal of a migrated WATCHMAN device combined with a modified maze procedure was successfully performed, resulting in normal sinus rhythm at 2-month follow-up.
