SV\u2013PA shunts using the expanded polytetrafluoroethylene valved conduit were implanted in 18 patients (valved SV\u2013PA group), and another 18 patients underwent modified Blalock\u2013Taussig shunt during NP (modified Blalock\u2013Taussig shunt group). All valved conduits were made in our institution in advance.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>No differences in baseline characteristics were found between the groups, except for shunt size. During a median 2.9 (interquartile range 0.4\u20136.4, maximum 14.2) years of follow-up, 8 (22.2%) patients died across both groups. There were no statistically significant differences in early mortality (5.5% vs 11.1%, P\u2009=\u20090.55) and overall survival rates at 5\u2009years (80.8% vs 71.4%, P\u2009=\u20090.48) in the valved SV\u2013PA and modified Blalock\u2013Taussig shunt groups. No statistically significant difference was observed in the frequency of interventions between the groups (31% vs 33%, P\u2009=\u20091.0). At the time of the bidirectional Glenn procedure, the systemic ventricular end-diastolic volume index was significantly lower (84\u2009\u00b1\u200924 vs 106\u2009\u00b1\u200931\u2009ml\/m2, P\u2009=\u20090.05) and the ejection fraction was significantly greater (62\u2009\u00b1\u20098% vs 55\u2009\u00b1\u20099%, P\u2009=\u20090.03) in the valved SV\u2013PA group. There was no statistically significant difference in the pulmonary artery index (228\u2009\u00b1\u200985 vs 226\u2009\u00b1\u200960 mm2\/m2, P\u2009=\u20090.92).<\/jats:p>\n
