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 P(max), P(min) and P-wave dispersions (P(d)). RESULTS: In each group, the increases in postoperative maximum P-wave duration (P(max)) and minimum P-wave duration (P(min)) were statistically significant. There was no statistically significant difference between post- and pre-operative P(d) values. In the comparison between group 1 and group 2 in terms of postoperative P-wave changes (P(max), P(min), P(d)) 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.
