Pulmonary valve endocarditis is an extremely rare complication of aneurysm of the sinus of Valsalva. We report the case of a 26-year-old male patient who presented with pulmonary valve endocarditis which was associated with a ruptured aneurysm of the right sinus of Valsalva with aorto-right ventricular outflow tract fistula and aortic valve endocarditis. He underwent aortic valve replacement with a 23 mm pericardial bioprosthesis, reconstruction of the right sinus of Valsalva using a pericardial patch, and debridement of pulmonary valve leaflet vegetations. The operation was a complete success. Intraoperative transesophageal echocardiography showed no residual shunt within the reconstructed right coronary sinus, normal function of aortic bioprosthesis, and mild mitral, tricuspid, and pulmonary regurgitation. Postoperative antibiotics were continued and the patient recovered uneventfully.
