Key result
Amulet LAAO device placement can cause delayed pulmonary artery erosion presenting as late cardiac tamponade.
Case Report (n=1)
This case highlights a rare but severe complication of delayed pulmonary artery perforation and cardiac tamponade occurring 6 months after Amulet LAAO device placement.
Raises awareness of late pulmonary artery erosion after Amulet placement; leaves open true incidence and surveillance needs.
Left atrial appendage occlusion (LAAO) devices offer stroke prevention in atrial fibrillation for patients intolerant of anticoagulation. Device placement leading to bleeding and cardiac tamponade have been reported periprocedurally but delayed presentations have not been reported in the literature. We present the case of an Amulet LAAO device causing erosion and bleeding from the main pulmonary artery that presented with cardiac tamponade 6 months after device placement. The pulmonary artery defect was repaired primarily and buttressed with a pericardial patch with good result.

Wang et al. (2018) conducted a case report in Atrial fibrillation (n=1). Amulet left atrial appendage closure device was evaluated on Delayed presentation of pulmonary artery perforation and cardiac tamponade. An Amulet left atrial appendage closure device caused erosion and bleeding from the main pulmonary artery, presenting as cardiac tamponade 6 months after placement.
