[Surgical treatment of secondary atrial septal defect associated with mitral valve disease].

From March 1965 through August 1991, 703 patients with secondary atrial septal defect were treated surgically in our hospital. Among them, 32 cases (4.6%) were associated with mitral valve disease. The mitral valve lesion was repaired at the same time of closure of the atrial septal defect. The operative mortality was 6.3% and there was no late death. Follow-up study showed that heart function of the patients was improved obviously and most of them have resumed work or study. The clinical features, incidence, etiology, pathology and surgical techniques of secondary atrial septal defect associated with mitral valve disease were discussed.
