endocarditis cases. The majority of cases involve tricuspid valve. Isolated pulmonary valve
endocarditis is very rare. As previously reported the ratio was 1.5 to 2.0% in all endocarditis
and less than 90 cases of pulmonary valve endocarditis. This report presented a 9-year-old
girl with isolated pulmonic valve endocarditis with patent ductus arteriosus.
