Abstract | OBJECTIVE: METHODS: RESULTS: Cardiothoracic ratio and single ventricular diastolic dimension before bidirectional cavopulmonary shunt were acutely increased in group H (P=0.02, <0.001). There was no significant difference between the two different types of Norwood procedures. The pulmonary artery index for the right heart bypass operation was lower in group H than in group C (P<0.001). Oxygen saturation before bidirectional cavopulmonary shunt in group H decreased (P<0.001) and thus was lower than that in group C (P=0.003). Mortality and the postoperative clinical parameters of the right heart bypass operation were not different between the two groups. CONCLUSIONS: Patients with hypoplastic left heart syndrome showed hemodynamic instability of acutely increased cardiothoracic ratio, and single ventricular diastolic dimension despite decreased oxygen saturation interstage after stage I of a Norwood procedure. This suggests that this hemodynamic characteristics in hypoplastic left heart syndrome correlates with the higher mortality before second stage palliation than in found with single right ventricle patients.
