Abstract
Objective: To determine if there is an association between aortic coarctation (CoA) and intraventricular hemorrhage (IVH) in low birth weight (LBW) infants that may justify earlier intervention. While there is an increasing number of reports of successful early CoA intervention in LBW infants, there are no data to justify this approach.Material and methods: Retrospective review of the University Health System Consortium Clinical Data Base/Resource Manager, a national hospital discharge database. LBW (≤2 kg) infants, with and without IVH and isolated CoA were identified; IVH was stratified into low (grade 1 or 2) and high (grade 3 or 4) severity. Odds ratios were calculated for any, low and high-grade IVH with CoA.Results: Forty-six thousand and twenty LBW infants were identified; 3716 (8.1%) had IVH, 3001 (81%) with low, and 724 (19%) with high severity. Sixty-four infants had CoA, 13 had associated IVH (10 with low and three with high severity). The odds ratio for any IVH with CoA was 2.91 (95% CI 1.58–5.35), low severity 2.77 (95% CI 1.41–5.46) and high severity 3.45 (95% CI 1.07–11.07).Conclusions: In conclusion, this large retrospective database review found that LBW infants with CoA may be at increased risk of IVH. Further study is needed to determine if earlier catheter- or surgical-based intervention for CoA could reduce the risk of IVH in this population.
