Abstract

A 22 year old male presented with breathlessness on exertion, ecchymosis, jaundice and features of worsening right heart failure for the last fifteen days. On physical examination, he had a mid diastolic murmur in the tricuspid area and an ejection systolic murmur in the pulmonary area. Bone marrow histopathology report showed an increased in megakaryocytes count. Routine investigations reports were normal. Echocardiography and computerized tomography (CT) revealed a single mobile large intra cardiac mass originating from the right atrium and causing dynamic obstruction of the right ventricular inflow and outflow tract. Associated fatal thrombocytopenia did not respond to intravenous steroids or platelet transfusion. Patient could not be operated because of very low platelet count, and died during hospital stay before excision biopsy could be done. Pathological autopsy was not done. This is a rare case, as the fatal thrombocytopenia observed here was the result of mechanical effects like frictional and shear force, which can be attributed to the physical presence of a large intra cardiac mass resulting in obstruction to flow.
