Ultrasound of the cardiac tumor. A Two-chamber view in transthoracic echocardiography shows a 23 mm × 8 mm mass which was polyp-like-shaped, homogeneous, firm, mobile and solitary centered on the lateral wall of the left ventricle. B Grey and C Color doppler flow imaging of four-chamber view in transesophageal echocardiography shows that the mass had regular margins and was pedunculated, with a stalk originating from the LV wall, and the mass protruded into the left atrium during systole, resulting in mild mitral regurgitation. D View of left ventricular contrast-enhanced echocardiogram shows little contrast agent filling
