The Echocardiographic Evaluation of Intracardiac Masses: A Review

Echocardiography is an invaluable procedure for the evaluation of intracardiac masses, and can reliably identify mass location, attachment, shape, size, and mobility, while defining the presence and extent of any consequent hemodynamic derangement. With careful attention to mass location and morphology, and appropriate application of clinical information, echocardiography can usually distinguish between the 3 principal intracardiac masses: tumor, thrombus, and vegetation. Transesophageal imaging frequently adds additional important information to the assessment of mass lesions and should always be considered when image quality is inadequate or pertinent clinical questions remain unanswered with surface imaging. This review will focus on primary and metastatic tumors of the heart.
