Assessment of the vascularity of a left atrial mass using myocardial perfusion contrast echocardiography.

Emerging applications of myocardial contrast echocardiography (MCE) include the evaluation of myocardial perfusion, the improvement of the definition of intracavitary structures, and evaluation of the relative perfusion of a cardiac mass. We present a case of a patient that was found incidentally to have a cardiac mass on transthoracic echocardiography. MCE was used to evaluate the vascularity of the mass. This case is compared with another patient with a left atrial thrombus, which represents an "avascular" cardiac mass by MCE.
