A 44-year-old male patient was referred to our hospital for progressive dyspnea on exertion and a cardiac tumor disclosed by a computed tomographic image study (Figure 1, A). Operative exploration was performed 3 days later, in which a wide-based tumor infiltrating the left atrial appendage, left atrial anterior free wall, anterior annulus of the mitral valve, and anterior mitral leaflet was found. Tumor debulking and removal of the left atrial appendage were performed to relieve obstruction by the tumor. Malignant fibrous histiocytoma was documented by microscopic examination. Follow-up computed tomography performed before his first hospital discharge revealed residual tumor existing at the anterior atrial wall.

Figure 1. A, A 5 x 7-cm2 mass (arrow) in the left atrium adjacent to the anterior annulus of the mitral valve with a bilateral pleural effusion was found at the patient's first admission. B, Thirty-eight days after radical tumor excision and insertion of a prosthetic mitral valve (arrow), no evidence of tumor recurrence was found in the left atrium.

The tumor grew fast, for 30 days, to reach a diameter of 3.6 x 3.6 cm2 at his second admission for recurrent dyspneic symptoms. During the investigation process for possible cardiac . . . [Full Text of this Article]
