A Case of Patent Ductus Arteriosus Associated with Pulmonary Valve Endocarditis

ABSTRACT

Isolated infective endocarditis in the native pulmonary valve is unusual in non-intravenous drug user. Intravenous drug abuse, alcoholism, sepsis, catheter related infections and congenital heart diseases account for the majority of predisposing factors. We report a case of patent ductus arteriosus complicating infective endocarditis involving pulmonary valve. A 24-year-old female was admitted with fever of unknown origin Physical examination revealed continuous murmur at left 2nd intercostals space. Transthoracic and transesophageal echocardiography was performed and patent ductus arteriosus and vegetation at the pulmonary valve were noted. Chest CT scan revealed multiple patch infiltrate suggestive of septic emboli. After 4 weeks of antibiotic treatment, she had no clinical signs of fever, and blood culture be negative. Percutaneous trans-catheter closure of patent ductus arteriosus was done after 2 months.
