However, despite good early results, they lack durability. This study was designed to compare single-center results of implantation of 3 types of right ventricular outflow tract conduit, in terms of patient survival, graft failure, reoperation, and risk factors for reoperation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>One hundred and forty-three pediatric patients who underwent right ventricular outflow tract conduit implantation between January 2006 and December 2018 were reviewed. We stratified conduits by aortic, pulmonic homograft, and Contegra; 74 aortic homografts, 61 pulmonic homografts, and 8 Contegra conduits were implanted. Median age at implantation was 3 years. The primary diagnosis was truncus arteriosus in 41.3%. We analyzed the role of sex, age, diagnosis, and graft size. Endpoints included freedom from graft failure, freedom from reoperation, and survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The survival rate was 83.2% at 10 years. Freedom from graft failure at 2, 5, and 10 years was 100%, 97.9%, and 63.4%, respectively. Freedom from reoperation was 85.8% for pulmonic homografts and 74.9% for aortic homografts at 10 years, and 100% for Contegra at 6 years. Multivariable analysis identified conduit diameter &lt;18\u2009mm as a risk factor for reoperation (hazard ratio: 3.16, 95% confidence interval: 1.38\u20137.23, p\u2009=\u20090.007).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Homograft valves used for right ventricular outflow tract reconstruction provided excellent long-term durability and late survival. The only factor that adversely affected graft longevity was small graft size (diameter &lt;18\u2009mm).
