Key result
Placement of a left atrial appendage closure device caused critical compression of the proximal circumflex coronary artery, which was resolved by device repositioning and stenting.

Coronary angiography may be recommended before LAA closure to anticipate or prevent left circumflex coronary artery occlusion.
Alerts to rare circumflex compression during LAA closure; hypothesis-generating for pre-procedural angiography.
Nowadays, percutaneous left atrial appendage (LAA) closure is spreading, and a large number of patients with this procedure have concomitant coronary artery disease. With the presented case it could be concluded that coronary angiography is recommended before LAA closure.

Katona et al. (2015) conducted a case report in Atrial fibrillation (n=1). Left atrial appendage closure device was evaluated on Coronary artery compression/occlusion. Placement of a left atrial appendage closure device caused critical compression of the proximal circumflex coronary artery, which was resolved by device repositioning and stenting.
