Muller, Smith, Dammann, Adams, and Darsie1 recently reported a series of 18 patients in whom closure of an interatrial septal defect was attempted. The Gross "well" technique was used in 15 cases and the atrioseptopexy method in 3 others. The defect was successfully closed in 14 patients, all of whom obtained good clinical results.
Sixteen of these patients are included in the present review, together with an additional 13 cases in which an attempt was made to close the defect by the atrioseptopexy technique, four cases in which closure was effected by open cardiotomy and direct suture of the defect and one case in which closure was attempted by the Gross "well" technique. While the exact incidence of defects of the atrial septum is unknown, there is good clinical evidence to suggest that this anomaly is one of the most frequent congenital cardiac defects. It has been generally considered
