Unexpecteddetection of Floating Thrombi in Left Atrium After Left Atrial Appendage Ligation With Atriclip Device: A Case Report

AtriClip device has demonstrated an excellent efficacy, long-term durability and safety of left atrium appendage (LAA) closure. We report, the unexpected postoperative transesophageal echocardiography (TEE) finding of thrombi in left atrium (LA)after deployment of an AtriClip in a 73-year-old man with chronic atrial fibrillation and 3-vessel-coronary artery disease undergoing coronary artery bypass grafting (CABG) surgery and LA appendage ligation. The heart was re-arrested and thrombi were retrievesuccessfully through a left atriotomy. This case emphasizes the unanticipated role of AtriClip in dislodging the thrombus from LAA, in addition to the importance of sufficient and well-founded imaging (Transesophageal Echocardiogram/Multidetector Computed Tomography) before and after the deployment of AtriClip device.
