Comparison of primary repair and patch plasty procedure on the P wave in adult atrial septal defect closure.

INTRODUCTION

In this study we compared the effects of two different surgical procedures for closure of adult atrial septal defect (ASD) on postoperative P-wave changes.

METHODS

Patients who underwent cardiac surgery for secundum type ASD closure were evaluated retrospectively. Seventy-two patients with primary repair of ASD and 29 patients with pericardial patch plasty repair were compared according to Pmax, Pmin and P-wave dispersions (Pd).

RESULTS

In each group, the increases in postoperative maximum P-wave duration (Pmax) and minimum P-wave duration (Pmin) were statistically significant. There was no statistically significant difference between post- and pre-operative Pd values. In the comparison between group 1 and group 2 in terms of postoperative P-wave changes (Pmax, Pmin, Pd) there was no statistically significant difference.

CONCLUSION

Comparing patch plasty and primary repair for the surgical closure of ASD in the early to mid-postoperative period, no difference was found and both surgical procedures can be performed in adult ASDs.
