pulmonic valve endocarditis with pulmonary artery endarteritis in a young man with congenital ventral septal defect

BACKGROUND: Isolated pulmonic valve endocarditis is a rare condition. The clinical and laboratory finding are not specific and experiences about that are limited. Most cases of that occur in children with congenital heart disease or in intravenous drug abusers and the main predisposing factor in adults is intravenous drug abuse. The most common pathogens are staphylococcus aurous and coagulase negative staphylococcus.

   CASE REPORT: In this case report we present a 27 years old man with chronic fever (4 months) and a history of congenital ventral septal defect (VSD). Echocardiography revealed the pulmonic valve and pulmonary artery vegetations. He referred for surgery after 3 weeks of intravenous antibiotic therapy.

   CONCLUSION: Careful evaluation of pulmonic valve in echocardiography should be done, when ever vegetation is not detected in other valves, and clinical suspicion for infective endocarditis is high.
