"Double-barrel endocarditis".

We report a case of an 18-year-old woman who presented with infective endocarditis (IE), in two conduits percutaneously delivered in the right ventricle outflow tract ("double-barrel endocarditis"). The patient's clinical presentation, echocardiogram findings, infectious agent, clinical management, surgical approach, and follow-up assessment are described. Percutaneous pulmonary valve implantation has emerged as a viable therapy for conduit dysfunction in the right ventricular outflow tract. Although the percutaneous approach has several advantages, this strategy and the valves used are not complication-free. IE after transcatheter valve deployment has evoked the growing concern, as there is a higher incidence in these patients compared with patients with surgically repaired pulmonary valves. As a result, this type of surgical treatment is especially important.
