A<unk>  <unk>  or "single ventricle", is a congenital heart defect appearing in 5 in newborns, where both the<unk>  atrium and the right atrium feed into the<unk>  ventricle. The right ventricle is hypoplastic or does not exist. Both atria communicate with the ventricle by a single atrio-ventricular valve. There is a big shunt<unk> -right with a quickly evolutive pulmonary hypertension. Without life-prolonging interventions, the condition is fatal, but with intervention, the newborn may survive. Even if there is no foetal sickness, the diagnosis can be made in utero by foetal echocardiography.
