Right-sided IEoccurs in 5%–10% of endocarditis cases, and pulmonary valve (PV) is involved in less than 2% of such patients.Literature data are few, and optimal treatment methods, indications for surgery, and types of operative techniquesare still under debate. We present an adult patient with a rare combination of the ventricular septal defect (VSD)and PV IE who underwent surgical treatment. Neocuspidization with autologous pericardium was utilized for thereconstruction of his PV. We discuss details of this novel surgical technique.展开更多
