The median age and body weight at operation were 16\u2009months (25th\u201375th percentile: 8\u201332) and 8.3\u2009kg (6.4\u201310.6). Sixteen patients were neonates (9.0%). Selected conduit sizes were 12\u2009mm in 28 patients (15.7%), 14\u2009mm in 67 patients (37.6%), 16\u2009mm in 66 patients (37.1%), 18\u2009mm in 5 patients (2.8%) and &amp;lt;12 mm in 12 patients (6.7%). Fifty-six grafts (31.4%) were ring supported. Proximal branch pulmonary arteries were concomitantly augmented in 85 patients (47.5%). Follow-up was completed in all patients and the median follow-up period was 3.1\u2009years (1.3\u20135.1).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The overall, conduit explantation-free and conduit infection-free survival rates at 5\u2009years were 91.3%, 71.0% and 83.7%, respectively. Infection (P\u2009=\u20090.009) and common arterial trunk (P\u2009=\u20090.024) were risk factors for explantation. Conduit durability was shorter in smaller one (P\u2009&amp;lt;\u20090.001). Catheter interventions (for conduit to proximal branch pulmonary artery)-free survival rates at 5\u2009years was 52.9%; however, need for catheter interventions was not a risk factor for conduit explantation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Mid-term outcomes of reconstruction of the right ventricular outflow tract to the proximal branch pulmonary arteries with Contegra were acceptable. The need for explantation over time was higher in smaller conduits. Conduit infection was a strong risk factor for conduit explantation. Frequently and repeated catheter interventions effectively extended the conduit durability.<\/jats:p>\n
