TEE artifacts such as reverberations of the left upper pulmonary vein ridge can mimic LAA thrombus and should be recognized during LAA closure.
Clinicians should recognize LUPV ridge reverberation on TEE to avoid LAA thrombus misdiagnosis; case report leaves open validation in larger series.
: Transesophageal echocardiography (TEE) represents the gold standard technique to detect left atrial appendage (LAA) thrombosis. Several conditions may be erroneously interpreted as LAA thrombus at TEE, including artifacts mimicking thrombi. We report a case of a 78-year-old man with atrial fibrillation and contraindication to anticoagulation who was referred to our institution for percutaneous left appendage closure with a transcatheter trans-septal approach. Intraoperative transesophageal echocardiography revealed a thrombus-mimicking image, related to reverberations of left upper pulmonary vein ridge, located at twice the distance of the ridge from the transducer.

D’Amico et al. (2014) conducted a case report in Atrial fibrillation (n=1). Transesophageal echocardiography during percutaneous left appendage closure was evaluated on Detection of thrombus-mimicking image. Intraoperative transesophageal echocardiography during left atrial appendage closure revealed a thrombus-mimicking image related to reverberations of the left upper pulmonary vein ridge.
