Background: Repair for complete atrio-ventricular septal defect (CAVSD) would be simpler by ventricular septal defect (VSD) direct closure in selected cases associated with shallow VSD. However, there are few reports of the mid-term and long-term outcome of this procedure.
Objective: We reviewed our cases of CAVSD repair consisting of VSD direct closure.
Patients: Since April 2000, six patients have undergone CAVSD repair by VSD direct closure in our department. The mean age at operation was 6.3 ± 3.3 months, and mean body weight was 5.3 ± 1.2 kg. Mean follow-up was 4 years and 6 months.
Result: No early or late mortality occurred. At operation, mean depth of VSD was 5.8 ± 1.9 mm. Aortic cross-clamp time was a mean of 44 ± 14 min. Extra-corporeal circulation time was a mean of 86 ± 24 min. Postoperative regurgitation across the AV valve was less than moderate in all cases. Neither residual shunt at VSD level nor left ventricular outflow tract obstruction was demonstrated.
Conclusions: The repair of CAVSD by VSD direct closure simplifies the procedure and does not interfere with valve function. This procedure is an effective option for CAVSD repair associated with shallow VSD.
