Early repair of complete atrioventricular septal defect has better survival than staged repair after pulmonary artery banding: A propensity score-matched study

Abstract

OBJECTIVES: Complete atrioventricular septal defect (cAVSD) repair is usually performed between 3 and 6 months of age. However, some children present with early heart failure requiring intervention. It is unclear whether primary complete repair or initial pulmonary artery banding (PAB) provides better outcomes. METHODS: All patients (n = 194) who underwent surgery for cAVSD younger than 3 months of age between 1990 and 2019 were included. Propensity score matching was performed on risk factors for mortality. RESULTS: Primary complete repair was performed in 77.8% (151/194), whereas PAB was performed in 22.2% (43/194). Children who had PAB were younger (P < .01), had lower weight (P < .001), ..
