Key result
In common ventricle, lateral outlet chambers link to greater systemic-pulmonary O2 saturation differences than anterior chambers.

Anatomic position may influence mixing in common ventricle; leaves open whether outlet chamber classification informs management or trial design.
Observational (n=42)
p-value: p=<0.001
In patients with a common ventricle, systemic arterial oxygen saturation variation is largely predictable based on pulmonary and systemic blood flow, and is influenced by the position of the outlet chamber.
Macartney et al. (1976) conducted an observational in Common ventricle (n=42). Outlet chamber position and great artery relationship was evaluated on Systemic arterial minus pulmonary arterial O2 saturation (p=<0.001). In patients with common ventricle, systemic arterial minus pulmonary arterial O2 saturation was significantly higher in those with malposition and lateral outlet chambers than anterior outlet chambers (P<0.001).
