Abstract

Primary cardiac tumors are rare and myxoma is the most common tumor among them. Cardiac myxoma usually occurs in the left atrium. Myxoma originating from mitral valve is extremely rare. We report a case of mitral valve myxoma. The tumor originated from the anterior mitral valve leaflet. The tumor was completely removed and replacement of the mitral valve was not done.

Figure

• 

  Fig. 1 Brain magnetic resonance imaging. High signal intensity lesion on diffusion weighted imaging (A) with decreased signal intensity on apparent diffusion coefficient value at left precentral gyrus (B) was observed which indicates hyperacute infarction.

• 

  Fig. 2 The transthoracic echocardiography (A and B) and transesophageal echocardiography (C and D) showed a 1 × 1 cm sized, highly mobile mass (arrows) on the anterior mitral valve leaflet. LV: left ventricle, LA: left atrium, RV: right ventricle, RA: right atrium.

• 

  Fig. 3 Whitish, round, and soft mass (arrow) was found on the anterior mitral valve leaflet (A) and it was completely excised from the mitral valve (B).

• 

  Fig. 4 Histologic examination showed spindle-shaped cells and stellate cells in a myxoid stroma (H&E stain, × 100).
