Abstract

Percutaneous pulmonary valve implantation is an alternative to surgical replacement for patients with right ventricular outflow tract dysfunction—such as those who have undergone surgery for tetralogy of Fallot, truncus arteriosus, or pulmonary atresia with ventricular septal defect and a right ventricle-to-pulmonary artery conduit, as well as patients with severe pulmonary regurgitation following pulmonary valvuloplasty. In our country, the Melody® balloon-expandable valve (Medtronic), the Pulsta™ self-expanding valve, and, more recently, the Myval™ balloon-expandable valve are currently marketed. The Myval™ is primarily used for aortic valve replacement but is also used for pulmonary valve replacement or valve-in-valve replacement of the mitral or tricuspid valve. We present the first three cases of Myval™ pulmonary valve implantation performed in Peru in adolescent patients with right ventricular outflow tract dysfunction following surgery for tetralogy of Fallot.
