Sufficient time has passed now and enough experience has been gained to evaluate some of the factors which are important in determining the outcome of cardiac procedures. This paper is an analysis of the surgical treatment of 231 patients with atrial and ventricular septal defects operated upon before July 1, 1959, and is an attempt to point out the factors influencing the mortality and morbidity and the results in this group of patients.

The total number of cases has been divided into the groups shown in Figure 1. Their age range and
