Incremental value of three-dimensional and contrast echocardiography in the evaluation of endocardial fibroelastosis and multiple cardiovascular thrombi: A case report.

Background: Endocardial fibroelastosis (EFE) is a rare heart disease characterized by thickening of the endocardium caused by massive proliferation of collagenous and elastic tissue, usually leading to impaired cardiac function. Multimodality cardiovascular imaging for the evaluation of EFE with thrombi is even rarer.
Case Summary: We report a rare case of EFE associated with multiple cardiovascular thrombi. Three-dimensional (3D) and contrast echocardiography (CE) were used to assess ventricular thrombi. Anticoagulant therapy was administered to eliminate the thrombi. The peripheral contrast-enhanced thrombi with the highest risk were dissolved with anticoagulant therapy at the time of reexamination, which was consistent with the presumption of fresh loose thrombi.
Conclusion: This new echocardiography technique has a great advantage in the diagnosis and treatment of EFE. On the basis of conventional echocardiography, 3D echocardiography is used to display the position, shape, and narrow base of the thrombus. CE does not only help to confirm the diagnosis of thrombus, but also determines its risk.
