Demographic and clinical variables were collected at baseline and at follow-up and analyzed as predictors. The occurrence of bloodstream infection (BSI), defined as a bacterial infection treated with \u22654 weeks of antibiotics, served as our primary outcome. The mean age at implantation for the study population was 21.5\u00b111 years, and tetralogy of Fallot was the cardiac condition in 59%. During a median follow-up of 19 months, 14 patients experienced BSI (9.5%; 95% confidence interval, 5.3%\u201315%). Of these, 4 (2.7%) patients had Melody valve endocarditis. Two patients died during the event, neither of whom had known valve involvement. The median procedure to infection time was 15 months (range, 1\u201356). In univariate analysis, male sex, previous endocarditis, in situ stents in the right ventricular outflow tract, and presence of outflow tract irregularities at the implant site were associated with BSI occurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions\u2014<\/jats:title>\n                    <jats:p>In this cohort, 9.5% of patients who underwent Melody percutaneous pulmonary valve implantation experienced subsequent BSI, occurring 1 to 56 months after implant, and 2.7% of patients had prosthetic endocarditis. Our findings suggest that patient and nonvalve anatomic factors may be associated with BSI after percutaneous pulmonary valve implantation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/circinterventions.112.000348","type":"journal-article","created":{"date-parts":[[2013,6,11]],"date-time":"2013-06-11T22:02:14Z","timestamp":1370988134000},"page":"301-310","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":89,"title":["Bloodstream Infections Occurring in Patients With Percutaneously Implanted Bioprosthetic Pulmonary Valve"],"prefix":"10.1161","volume":"6","author":[{"given":"Jonathan","family":"Buber","sequence":"first","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Bergersen","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James E.","family":"Lock","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kimberlee","family":"Gauvreau","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse J.","family":"Esch","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Landzberg","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne Marie","family":"Valente","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas J.","family":"Sandora","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey C.","family":"Marshall","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology (J.B., L.B., J.E.L., K.G., J.J.E., M.J.L., A.M.V., A.C.M.) and the Division of Infectious Diseases, Departments of Medicine and Laboratory Medicine (T.J.S.), Boston Children\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(95)00733-4"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2009.04.023"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.109.921692"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.591438"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2010.07.056"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2004.11.001"},{"key":"e_1_3_2_8_2","doi-asserted-by":"crossref","unstructured":"Calderwood SB Swinski LA Karchmer AW Waternaux CM Buckley MJ.
