PFO indicates patent foramen ovale. Includes patients with a biventricular outcome from birth or after intermediate univentricular palliation. Biventricular outcome vs single-ventricle outcome *including or †excluding technically unsuccessful interventions. Data are presented as mean±SD unless otherwise indicated.
