Transesophageal echocardiographic recognition of infiltrative cardiac sarcoma mimicking mitral stenosis

Unusual cause of heart failure: Mitral stenosis and pulmonary venous obstructions caused by the direct invasion of primary cardiac sarcoma

Cardiac tumor can produce a variety of symptoms and clinical findings depending on the location, size, and histologic type. It may cause heart failure usually by interfering with intracardiac blood flows associated with the mass effects. Here, we report an extremely rare case of heart failure caused by primary cardiac sarcoma with a review of the literature. The cause of heart failure was moderate to severe mitral steno-insufficiency due to the direct tumoral invasion of mitral valve apparatus combined with obstruction of the pulmonary veins.
