Résumé
<p>A 75-year-old man who presented with fever and cough was given a diagnosis with active pulmonary valve endocarditis and transferred to our institution. Blood cultures were positive for <i>Enterococcus faecalis</i>, and transthoracic echocardiography showed a mobile vegetation attached to the pulmonary valve. Despite an 8-week treatment with antibiotics, a relapse of the infection required surgery. During the surgical procedure, we found that the vegetation had destroyed all of the pulmonary valve leaflets. After excising the pulmonary valve leaflets, we implanted a bioprosthetic valve and closed the pulmonary artery with autologous pericardium. The patient completed a 6-week course of intravenous antibiotics and was discharged on postoperative day 68. Postoperative transthoracic echocardiography demonstrated an adequate effective orifice area index. Our case report of isolated pulmonary valve endocarditis without predisposing factors is rare. The implantation of a bioprosthetic valve and enlargement with an autologous pericardial patch is an effective option for achieving a satisfactory hemodynamic profile.</p>
