Repair of multiple muscular ventricular septal defects: Septal obliteration technique
MetadataShow full item record
Background: The management of the apical multiple muscular ventricular septal defects (VSDs) remains still controversial. There are various surgical techniques and approaches for closure of "Swisscheese" VSDs. In this study, we report the outcome of multiple muscular VSDs repair, using the septal obliteration technique. Methods: We used the septal obliteration technique in five "Swiss-cheese" ventricular septal defects cases through right atriotomy. Four of the cases had isolated multiple VSDs. One case also had an aortic arch interruption type A, which was repaired prior to cardiopulmonary bypass. Their ages varied between 43 days and 6 years. Results: We did not experience any mortality or serious morbidity. Tracheostomy was required in one patient. There was no important residual shunt in postoperative period, except a minimal shunt in one case. Conclusion: The closure technique of "Swiss-cheese" trabecular multiple VSDs using a large single patch was not troubling. Transatrial approach prevented postoperative problems of ventricular incision. Using a large needle with a large pledgett is the key, which provides deep tissue penetration to avoid residual shunt.
