Five-month follow-up transthoracic echocardiogram with and without perflutren lipid microsphere contrast. (A) Perflutren lipid microsphere contrast-enhanced apical two-chamber view of the LV apical mass on follow-up imaging 5 months from the initial images demonstrating reduced size of the mass. (B) Perflutren lipid microsphere contrast-enhanced apical four-chamber view of the LV apical mass on follow-up imaging demonstrating reduced size of the mass. (C) Apical four-chamber noncontrast grayscale view of the LV apical mass on follow-up imaging demonstrating reduced size of the mass.
