We report a rare case of infective endocarditis after repair of a complete atrioventricular (AV) septal defect in a four-month-old patient. Perforation of a valve leaflet with progressive severe left AV valve regurgitation required surgical intervention. Valve reconstruction using fresh autologous pericardium was successfully accomplished. This reconstruction in association with prolonged antibiotic therapy resulted in complete recovery of the patient.
