[Adult patients with atrial septal defect]

Our material included patients older than 30 years who were diagnosed as having atrial septal defect during the period 1980-1993. A questionnaire was used during follow-up. 39 of a total of 42 patients were operated on. The mean follow-up time was 5.5 years. There was no operative mortality. Five patients had died by the time of follow-up. The three patients who had not been operated on had all died. The available literature gives no conclusive answer to the question of whether all patients with an atrial septal defect should be offered surgery or not.
