[Infective Endocarditis in Right Ventricle( RV)-Pulmonary Artery( PA) Conduit Late after the Ross Procedure;Report of a Case].

ABSTRACT

Ross procedure has been found to have a lower incidence of infective endocarditis compared to other aortic replacement procedure using prosthetic valves. We report a case of 25-year-old man who underwent Ross procedure for congenital aortic stenosis and regurgitation when he was 7 years old. He presented with fever and was highly suspected of infective endocarditis. All sets of blood cultures were positive for Heamophilus parainfluenzae. Autologous pericardial pulmonary valve was severely stenotic and computed tomography (CT) scan and radio isotope (RI) scan revealed infection at the stenotic valve. We performed right ventricle (RV)-pulmonary artery (PA) conduit replacement and he was discharged after completion of intravenous antibiotic treatment. We experienced a rare case of infective endocarditis in a patient late after Ross procedure. Prophylaxis against infective endocarditis is mandatory even in patients with infection resistant Ross procedure.
