Utilization of double-orifice valve plasty in correction of atrioventricular septal defect.

BACKGROUND

Atrioventricular valve regurgitation represents the principal indication for reoperation after repair of atrioventricular septal defect. Deciding how to correct atrioventricular valve regurgitation is challenging in some cases because of the complexity of the anatomic features. This report deals with our surgical experience in using a double-orifice valve plasty technique in cases with atrioventricular septal defect.

METHODS

From August 2002 to August 2004, 8 patients underwent double-orifice valve plasty in surgical correction of atrioventricular septal defect. Anatomic types were partial (6 patients), intermediate (1 patient), and complete (1 patient). After the mitral cleft was closed, moderate to severe atrioventricular valve regurgitation was still present in these patients. Double-orifice valve plasty was used in the mitral valve in 7 patients and in the tricuspid valve in 1.

RESULTS

No hospital deaths or postoperative morbidity occurred. The follow-up ranged from 6 months to 30 months (median, 14.4 months). No or trivial atrioventricular valve regurgitation was found in 6 patients and mild atrioventricular valve regurgitation was present in 2.

CONCLUSIONS

Double-orifice valve plasty is an easy and effective additional procedure for children and for adult patients who have moderate or severe atrioventricular valve regurgitation after repair of atrioventricular septal defect.
