Late recurrence of pulmonic valve endocarditis in an adult patient with ventricular septal defect: a case report.

A 54-year-old female patient with a congenital ventricular septal defect (VSD) was admitted to the authors' hospital for an investigation of mild fever of four months' duration. Her history revealed pulmonary valve endocarditis contracted 18 years previously. Echocardiography revealed an echogenic mobile mass on the pulmonic valve that caused mild regurgitation, while blood cultures were positive for Streptococcus viridans.
