Percutaneous pulmonary valve implantation (PPVI) has revolutionized the management of right ventricular outflow tract dysfunction after repaired congenital heart disease. The technology is considered to be safe, with a relatively low complication rate. Infection is one of the described complications of PPVI, and to date five cases of culture-positive infective endocarditis of percutaneously implanted pulmonary valve have been reported worldwide. Herein is reported the first ever case of culture-negative endocarditis of a percutaneously implanted pulmonary valve, caused by Bartonella henselae, five years after implantation in a 15-year-old patient with a repaired truncus arteriosus.
