[The surgical correction of an ostium secundum defect in the interatrial septum].

The operation of choice for correction of secundum type atrial septal defect is cardiopulmonary bypass. Combination of atrial septal defect with partial anomalous pulmonary venous drainage is considered absolute indication for bypass operation. The authors apply an original method for closure of the defect without resorting to bypass. For a period of seven years they have operated 240 patients from 3 to 54 years of age. Eighty four patients have been operated by the covered method of professor Zorin and in 23 correction of venous sinus defect was performed.
