BACKGROUND: A subset of patients who underwent Fontan operations has two adequate-sized ventricles, but an anatomic biventricular circulation cannot be achieved because of complex morphology or for technical reasons.

METHODS: A binational Fontan Registry of patients (n = 1,377) was analyzed to identify those patients with two adequate ventricles.
