This study sought to test whether anomalous cardiac and aortic structures can be differentiated from native tissue and artifacts by physical properties of tissue motion using transesophageal tissue Doppler echocardiography (TDE). TDE was employed in 85 consecutive @entity1 after @entity2383 had been detected by conventional transesophageal echocardiography (TEE). The control group consisted of 40 randomized @entity1 . Certainty of diagnosis was divided into 4 categories, and TDE signals were related to particular @entity2383 by a blinded second observer. A mechanical model of a beating ventricle was constructed and suspended in a water bath. Synthetic material was utilized to simulate anomalous intracavitary structures with varying shape, consistency, and attachment. Incoherent motion was present in @entity47 , freely oscillating thrombi, fourth-degree aortic plaques, @entity3181 , @entity340 , @entity5 , and in normal valve leaflets and papillary muscles. Within 15 seconds vegetations could be detected in 17 @entity1 (68%) using TDE versus 5 @entity1 (20%) using only conventional imaging. Coherent motion with a phase difference occurred due to damped oscillation. This phenomenon occurred in 5 @entity1 with thrombi of the left atrial appendage (100%), in 3 ventricular clots (75%), and in 2 @entity1358 in the right atrium (100%). Rapid identification of clots could be achieved in 15 @entity1 (71%) versus 12 @entity1 (57%). Concordant motion was shown in third-degree aortic plaques, @entity340 , and aortic intramural @entity1410 , but diagnostic benefit could not be demonstrated. In 41 @entity1 (48%) histopathologic and intraoperative results confirmed echocardiographic findings. Motion patterns could be reproduced independently of the heart rate by model experiments. This study demonstrates that @entity5981 expedites the detection of vegetations in @entity884 . Diagnostic certainty can be increased as well for @entity715 formations.

Usefulness of motion patterns indentified by tissue Doppler echocardiography for diagnosing various cardiac masses, particularly XXXX .
