Key result
LAAO device embolization to the infrarenal aorta can present with acute neurologic symptoms.
Why the study?
Although procedural success rates for transcatheter left atrial appendage occlusion are high, device-related complications such as device embolization remain recognized risks.
Case Report (n=1)
This case report highlights a rare but serious complication of left atrial appendage occlusion device embolization to the infrarenal aorta presenting with acute neurologic symptoms.
Rare LAAO device embolization to aorta may present neurologically; case report leaves open incidence and prevention data.
Transcatheter left atrial appendage occlusion is now widely performed in the United States using two FDA-approved device platforms: the WATCHMAN series and the Amplatzer Amulet.1–6 Although procedural success rates are high, device-related complications remain recognized risks. Pericardial effusion represents the most common serious procedural complication, while device embolization occurs in approximately 0.2–0.7% of cases and is typically related to malpositioning, suboptimal sizing, or unfavorable appendage anatomy.

Barney et al. (2026) conducted a case report in Left atrial appendage occlusion device embolization (n=1). Fluoropolymer-coated left atrial appendage occlusion device was evaluated. Embolization of a fluoropolymer-coated left atrial appendage occlusion device to the infrarenal aorta can present with acute neurologic symptoms.
