Figure 3 (A) A left ventricular apical mass (apical four-chamber view). (B) The mass showed no enhancement with contrast, whereas the adjacent myocardium demonstrated enhancement. (C) There was no enhancement of the mass or adjacent myocardium after a high-mechanical index impulse destroyed the contrast agent. (D) The surgical specimen demonstrated no staining with CD34 antibody and minimal cellularity, consistent with thrombus. (E) Perfusion curves of video intensity over time demonstrated no increase in video intensity in the mass from baseline, whereas video intensity increased within the myocardium.
