72-year-old woman after a left atrial appendage occluder

Abstract

A 72-year-old woman presented for routine echocardiography 6 months following percutaneous insertion of a left atrial appendage occluder (LAAO) due to atrial fibrillation with contraindications to anticoagulation. The procedure was uncomplicated, and she was clinically well. On echocardiography an abnormality was seen in the posterior pericardial space (Figure 1, arrows).
