An integral part of the heart with an atrioventricular septal defect and a Rastelli type A valve configuration is left ventricular outflow tract obstruction. Current surgical techniques do not cater to this particular anatomic facet, and left ventricular outflow tract obstruction has been reported as a postoperative problem. The present study has focused on the surgical anatomy of the mode of attachment of the left superior atrioventricular valve and its relationship to the left ventricular outflow tract. It appeared that the anchoring of the superior leaflet was a major factor in limiting the excursions of the superior leaflet, contributing also to the tightness of the subaortic left ventricular outflow channel. On that basis a surgical repair is proposed in which the greater part of the tightly bound superior leaflet is detached from the septal crest, so that the left ventricular outflow tract is widened.
