A Case Report of Isolated Pulmonary Valve Endocarditis

A 50s years-old man admitted with high fever and general malaise. He had a history of medication of diabetes and run a nail into his sole of a foot 1 month before admission. A chest X-ray and CT images showed cardiomegaly and multiple pulmonary emboli. Laboratory data and blood culture showed sepsis and disseminated intravascular coagulation status caused by streptococcus dysgalactiae. To elucidate the cause of sepsis, trans-thoracic echocardiography performed and found a 18 mm sized vegetation on the pulmonary valve. Further examination of trans-esophageal echocardiography revealed no any other valve lesions and congenital heart disease. Antibiotics administration succeeded against infection, and he got well without cardiac surgery. Here we report a rare case of isolated pulmonary valve endocarditis found by echocardiography.
