title: [Surgical treatment of severe forms of atrioventricular canal].
abstract: Report of a personal experience of surgery in severe forms of artrio-ventricular canal. These include on the one side complete forms. They have in common clinical and haemodynamic characters which make difficult their recognition before their surgical exploration. In the forms with very intense mitral incompetence and equal pressures on the right and left sides, the indication for operation is often a delicate procedure. hen a marked felt-tto-right shunt persists, when there is no excessive peripheral arterial saturation when the PR/SR ratio is lower than 0.7, surgery should be performed. The middle-term results of the patients who survived the operation are on the whole very encouraging, and justify the resort to surgical repair, the more so that the spontaneous prognosis of the disease is often a severe one.
