Cardiac Masses and Tumors
Primary tumors of the heart are infrequent across all age groups, with a described prevalence of 0.001–0.03% in autopsy series. Secondary involvement of the heart by extracardiac tumors is 20–40 times more common than that by primary cardiac tumors.
When cardiac tumors are considered in the differential diagnosis, the most ideal initial method of evaluation is echocardiography, either transthoracic (TTE) or transesophageal (TEE)—depending on the clinical circumstances. The sensitivity of TTE and TEE for the detection of a cardiac mass is 93% and 97%, respectively. Therefore, TEE is more comprehensive and accurate than TTE in the evaluation of such masses. Moreover, TEE is particularly advantageous in evaluating right atrial tumors. Three-dimensional echocardiography can assess the size of cardiac masses and define the complex anatomy of the heart. If a cardiac lesion is identified, chest computed tomography with contrast enhancement and cardiac magnetic resonance imaging with contrast are superior modalities for the characterization of the lesions and the description of the extent of tumor involvement. They may also help exclude the possibility of the direct cardiac extension of a tumor, created by the adjacent mediastinal structures.
In this chapter, we will explain other masses such as thrombi, vegetations, cysts, normal structures, and artifacts.
