Isolated pulmonary valve endocarditis in a patient with aplastic anaemia

A 42-year-old female patient of aplastic anaemia on maintenance blood transfusion presented with a 3-week history of fever, cough, dyspnoea and pedal oedema. Upon examination she  was found to have severe pallor, temperature of 101°F, tachycardia, bilateral pitting pedal oedema, raised jugular venous pressure, ejection systolic murmur (grade 2/6) in pulmonary area and petechiae over extensor aspect of both lower limbs. Blood investigations revealed low haemoglobin, thrombocytopaenia and mild increase in serum creatine. Chest x-ray was normal. Initial 2D trans thoracic echocardiography performed after hospital admission was normal. Antibiotics were started empirically to treat a possible underlying infection. Subsequently, three sets of blood cultures grew Enterococcus faecalis. Upon searching for the source, repeat echocardiograph done showed 2×0.5 cm vegetation on both pulmonary leaflets with severe pulmonary regurgitation, all other valves were free of vegetations. She was treated with intravenous antibiotics for the endocarditis and improved.
