**5. Summary**

Echocardiography both transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), is the commonly available noninvasive method for the diagnosis of cardiac masses. Tumor size, location and texture, and its extension to adjacent organs, its attachment to cardiac structures, presence or absence of pericardial effusion, interference with valve function, any obstruction and tumor mobility could be evaluated by echocardiography. In patients with poor echo window, TEE gives superior results, however, in some patients for better evaluation of cardiac tumor and its extension, other imaging modalities such as MRI is needed. Extra cardiac structures could be visualized better in TTE then TEE which is important for surgeons for choosing the most suitable plan for surgery(7).
