BACKGROUND: Hybrid procedure is an alternative initial palliation for patients with hypoplastic left heart syndrome (HLHS). One major complication with this procedure is stenosis in the aortic arch isthmus possibly due to inflammation from the patent ductus arteriosus (PDA) stent. In adult studies, neutrophil/lymphocyte (N/L) ratio has been used as a marker for increased inflammation and has been associated with increased risk for coronary artery stent stenosis. The goal of this study was to determine if there were differences in N/L ratio between patients with HLHS undergoing hybrid procedure that required an arch intervention (AI-Group) vs. those that did not require an intervention (NAI-Group).
METHODS: Retrospective chart review was performed on patients with HLHS undergoing hybrid procedure between July 2002 and January 2013. Complete blood counts as well as differentials were recorded at four time periods: 1 day prehybrid palliation, one day posthybrid palliation, 1 week posthybrid palliation, and 3 weeks posthybrid palliation.
RESULTS: One hundred six patients were evaluated (AI-Group = 38, NAI-Group = 68). AI-Group generally had a higher N/L ratio vs. NAI-group and this was significant immediately 1 day posthybrid palliation: AI-Group vs. NAI-Group, prehybrid (2.95 ± 2.62 vs. 2.44 ± 1.71), 1 day posthybrid (5.95 ± 4.16 vs. 4.34 ± 3.87, P < .05), 1 week posthybrid (2.72 ± 3.01 vs. 2.28 ± 2.12), and 3 weeks posthybrid (1.85 ± 1.24 vs. 1.45 ± 1.16), respectively. Lymphocyte percentage was significantly lower in the AI-Group vs. NAI-Group 3 weeks posthybrid palliation (33.00 + 11.30% vs. 40.65 + 16.82%).
CONCLUSION: Patients that required an arch intervention after hybrid palliation had a higher N/L ratio immediately after the procedure. This may signify increased inflammatory reaction that places these patients at risk for stenosis. Future studies are needed to determine if N/L ratio is a robust marker to risk stratify patients undergoing the hybrid procedure for arch complications.
