case_images: (A) Two-dimensional transthoracic echocardiography showing a floating round-shaped hyperechoic mass on the anterior mitral valve (yellow arrow). (B, C) Transesophageal echocardiography showing a regular, round tumor (yellow arrow) that appeared to be attached to the anterior mitral valve leaflet by a small pedicle. LA = left atrium, LV = left ventricle, RA = right atrium.

case_images: Transthoracic echocardiography (TTE) revealed a floating round-shaped hyperechoic mass measuring 11 x 10 mm on the anterior MV, as shown in Figure 1A. Transesophageal echocardiographic (TEE) imaging depicted a regular, round tumor that appeared to be attached to the anterior leaflet MV by a small pedicle (Fig. 1B, C).
case_images: Noncontrast (A) and contrast-enhanced CT (B) imaging of the heart revealed an oval hypodense lesion (red arrow), which appeared to be attached to the anterior mitral valve leaflet by a small pedicle.

case_images: Noncontrast (Fig. 2A) and contrast-enhanced CT (Fig. 2B) imaging of the heart revealed an oval hypodense lesion, which appeared to be attached to the anterior mitral valve leaflet by a small pedicle.
case_images: Histological examination showed the branching avascular papilla, composed of the hyalinized collagen matrix, which were covered by the endothelium.
