Abstract

Aim:

We sought to compare and assess growth in single ventricle children with a systemic right or left ventricle in five time periods: at birth, before neonatal surgery, before the Glenn anastomosis and finally before and after the Fontan operation to 11 years of age.

Methods:

We reviewed medical records on 116 single ventricle patients operated at Rigshospitalet, Denmark from 1987 to 2007. Surgical procedures, feeding route, hemodynamic variables and anthropometric measurements such as weight and height were registered and converted to z-scores.

Results:

Ninety four single ventricle patients were included for analysis. Gestational age and birth weight was not significantly different between the left and right ventricle group. Before neonatal surgery and before the Glenn anastomosis, both groups showed equal growth retardation. However, a significant difference in catch-up growth was found before the Fontan operation. Thus, patients in the right ventricle group had a smaller median weight-for-age z-score compared with the left ventricle group in the pre-Fontan period (−1.9 and −1.6; p = 0.049) and in the post-Fontan period (−1.1 and −0.7; p = 0.034).

Conclusion:

After the Glenn anastomosis single ventricle children with a systemic left ventricle have better weight gain compared with children with a systemic right ventricle.
