The median age at Norwood and BCPS was 8 (7\u201311) days and 3.6 (3.1\u20134.6) months, respectively. There were 7 hospital deaths and 12 late deaths. Survival after BCPS was 90.3% at 1\u2009year and 86.2% at 2\u2009years. Total, right and left PA indices were 238 (195\u2013316), 136 (101\u2013185) and 102 (75\u2013130) mm2\/m2 at the time of BCPS, and they were 237 (198\u2013284), 151 (123\u2013186) and 86 (69\u2013108) mm2\/m2 at the time of Fontan. Left PA index decreased significantly between the time of BCPS and Fontan (P\u2009&amp;lt;\u20090.01). Nine patients needed partial takedown and additional APS due to failing BCPS, but the additional APS did not promote the PA growth significantly.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Preoperative PA index did not affect the mortality after BCPS.
