Preoperative and postoperative evaluation was done in 60 adult patients above 20 years of age among 152 patients, who had operation for the congenital atrial septal defect from January 1984 to June 1993 in the Department of Thoracic and
Cardiovascular
Surgery, Chonbuk National University Hospital.
Anatomically, the secundum type defect was present in 58 cases and the other two were ostium primum type defect. The defect were closed directly in 45 cases and with patches in 15 cases. Preoperative EKG findings revealed regular sinus rhythm in
81%,
arrhythmia 19%, RVH 32%, RAD 30%. Postoperative findinsg were regular sinus rhythm in 76%, arrhythmia 24%, RVH 25%, RAD 25%.
In hemodynamic data, the mean sPAP in patients over 40 years old was 41.91±14.33mmHg compared to 31.46±13.77mmHg in patients under 40 years old, and the difference between the two proups was stastistically significant. And then the patients
were
classified into groups(group A:sinus group, and group B: arrhythmia group) according to their preoperative rhythm. The patients in group B were older, had greater value of mean sPAP and Rp/Rs. Mean Qp/Qs was higher in group A. But the difference
between
two groups about the mean Qp/Qs and Rp/Rs was not significant.
Postoperative complications such as arrhythmia, pneumothorax or hemothorax occurred in 7 cases, but there was no operative mortality. The functional improvement were remarkable half of the patients who underwent surgery.
