Residual shunt after ductus arteriosus occluder implantation complicated by late endocarditis.

We report the case of a 20-year-old woman who had percutaneous closure of a patent ductus arteriosus (PDA) with a 17-mm Rashkind occluder when she was 4 years of age. A small residual shunt was noted on color-flow Doppler echocardiography immediately after the procedure and at 6-month follow-up. Because of the lack of hemodynamic complications, no additional intervention was performed. Sixteen years later, she presented with recurrent bilateral bronchopneumonia that required antibiotic treatment. Chest radiography during the third episode showed a right bronchopneumonia (Figure 1). At that time, new treatment with amoxicillin and clavulanic acid was given for 10 days, but fever persisted despite this course of antibiotics. Results of the physical examination showed blood pressure of 110/70 mm Hg, pulse of 92 bpm, temperature of
