[Reoperations for recurrent atrial septal defect].
The authors discuss seven cases of recurrent atrial septal defect (ASD) without an inferior border which were treated by surgery. A typical clinical picture of the anomaly with arterial hypoxemia being the leading symptom was encountered in all cases. The main cause of the complications was overestimation of the indications for Lewis' operation, i.e. ASD suturation. A good clinical result was produced in all cases of a repeated intervention with ASD repair with a graft.
