Contrast echocardiography for the evaluation of tumors and thrombi.

Contrast echocardiography is based on intravenous injection of microbubbles that act as blood flow tracers and increase ultra-sound signal. Contrast agents have shown to improve cardiac cavities opacification and endocardial border delineation in addition to helping perfusion evaluation. Contrast echocardiography has recently been used to evaluate cardiac masses. In this report we will describe three cases evaluated by contrast echocardiography: a left atrial myxoma (benign tumor), a lung adenocarcinoma metastasis (malign tumor), and one thrombus. Contrast echocardiography showed to be valuable in the diagnosis of the different types of cardiac masses.
