Abstract
OBJECTIVE
The objective of this study was to assess the safety of directly closing the septum primum during the correction of atrioventricular canal defects.
METHODS
We performed a retrospective analysis of our experience with direct closure of the septum primum during the repair of atrioventricular canal defect. The series consisted of 28 consecutive patients presenting with a partial (15 patients) and complete (13 patients) atrioventricular canal defect. The cleft in the atrioventricular valve was closed completely in 25 patients and partially in 3 patients (those with a small left lateral leaflet). In complete atrioventricular canal, the ventricular septum defect was closed with a patch of polytetrafluoroethylene (Gore-Tex, W. L. Gore & Associates, Inc, Flagstaff, Ariz) or xenopericardium. Follow-up was complete and ranged from 3 to 21 months (median 11 months).
RESULTS
There were no early or late deaths and no surgical complications. The septum primum defect was closed completely in all patients as assessed by echocardiography. All the patients were in sinus rhythmus, and none had even a temporary complete atrioventricular block. The surgical result and heart rhythm have remained stable over time.
CONCLUSIONS
Direct closure of the septum primum is an easy, quick, and safe procedure during repair of atrioventricular defects.
