Indication criteria of adult patients with atrial septal defects type II for surgery are not uniform so far. In a group of 150 adult patients with atrial septal defects type II operated in 1978-1987 at the cardiosurgical department in Brno the authors report the following results: a mortality on operation of 0.7% and a very satisfactory postoperative condition in almost all patients. In a group of 16 patients examined in 1978-1987 but not operated because of a defect of the atrial septum type II of minor haemodynamic impact the authors observed after long-term follow up a deterioration of the health status in four patients and they express therefore doubts on the rigorous criterium for operation a 1.5:1 left-to-right shunt in adult patients and assume that in some instances the defect is indicated for surgery even when the shunt is small.
