Pre-stage 2 angiograms were analysed to measure the size of the PA. The Nakata index was calculated to estimate PA growth. The ratio of the right PA to left PA cross-sectional area (RPA\/LPA) was used to calculate the difference in growth between the 2 branches. Study end points were shunt failure, shunt-related mortality and growth of the PAs.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>A total of 223 patients with hypoplastic left heart syndrome (RV\u2013PA group\u2009=\u2009137, mBTS group\u2009=\u200986) underwent the Norwood I procedure, and 186 patients (RV\u2013PA n\u2009=\u2009116, mBTS n\u2009=\u200970) achieved the stage 2 procedure. PA growth was better in patients with mBTS (Nakata index: RV\u2013PA\u2009=\u2009282, mBTS\u2009=\u2009315\u2009mm2\/m2, P\u2009=\u20090.021). LPA growth was worse compared to RPA growth in both groups (RPA\/LPA: RV\u2013PA\u2009=\u20091.21, mBTS\u2009=\u20091.29, P\u2009=\u20091.0). Patients with RV\u2013PA shunts experienced more frequent shunt stenosis compared to patients with mBTS (26 vs 2, P\u2009&amp;lt;\u20090.010). Freedom from shunt failure was 83.3\u2009\u00b1\u20093.2% and 94\u2009\u00b1\u20092% at 6\u2009months in the RV\u2013PA and mBTS groups, respectively (P\u2009=\u20090.003).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>PA growth is significantly better in patients who received an mBTS. Moreover, patients with an RV\u2013PA shunt more frequently experienced shunt failure due to shunt stenosis. However, survival after the NW procedure is not shunt dependent and growth of the LPA is less pronounced than RPA, regardless of the shunt type.<\/jats:p>\n
