Primary left atrial fibrosarcoma.
An elderly female with refractory cardiovascular symptoms due to functional mitral stenosis secondary to a primary left atrial fibrosarcoma is described. The symptoms are often nonspecific and most of the patients present first time with hemodynamic compromise. A high index of suspicion is essential for the early diagnosis of these highly malignant cardiac tumors because of their rarity, a wide spectrum of nonspecific symptoms and poor survival.
