Does real-time 3D TEE improve the differentiation of a bilobar left atrial appendage from a thrombus compared to 2D TEE?
Real-time 3D TEE can provide critical diagnostic information to differentiate a congenital bilobar left atrial appendage from a thrombus when 2D TEE imaging is ambiguous, potentially preventing unnecessary surgical interventions.
Mizuguchi et al. (2008) conducted a case report in Severe aortic stenosis and chronic atrial fibrillation with suspected left atrial appendage thrombus (n=1). Real-time three-dimensional transesophageal echocardiography (RT-m3D TEE) vs. Two-dimensional transesophageal echocardiography (2D TEE) was evaluated on Differentiation of bilobar left atrial appendage from thrombus. Real-time three-dimensional transesophageal echocardiography successfully differentiated a congenital bilobar left atrial appendage from a pathological thrombus suspected on 2D imaging.
