Long-Term Results of Reoperation for Left Atrioventricular Valve Regurgitation After Correction of Atrioventricular Septal Defects

After previous correction of AVSD, LAVVR can usually be corrected by valve repair. A very dysplastic valve may necessitate replacement. Overall survival is higher after repair than after replacement. In general, overall survival of patients reoperated on for LAVVR is favorable. The overall mortality rate after primary repair of AVSD is explained only for a small part by mortality after reoperation for LAVVR.
