Intracardiac echocardiography for verification for left atrial appendage thrombus presence detected by transesophageal echocardiography: the <scp>ActionICE II</scp> study

Abstract

With TEE, a false positive of an LAA thrombus may be indicated, especially when a thrombus is described as soft rather than solid. Our study suggests that ICE may be a valuable option for verification of a TEE-based diagnosis of a thrombus.
