Analysis of 8681 neonates with transposition of the great arteries: outcomes with and without Rashkind balloon atrial septostomy
ABSTRACT Rashkind balloon atrial septostomy is a common cardiac procedure aimed at improving systemic oxygenation in newborns with cyanotic congenital cardiac defects, such as transposition of the great arteries. Recent reports on the safety of this procedure were from limited series at single institutions. We analysed two complementary national databases to evaluate clinically relevant outcomes of this procedure.
We performed an analysis of transposition of the great artery patients nationwide using 15 years of the Nationwide In-patient Sample and three complementary years of the Kids' Inpatient Database. Variables included gender, race, age, and co-existing diagnoses. Outcomes included mortality, length of stay, and hospital charges. Comparison between patients undergoing Rashkind procedure or not was performed using Pearson's chi-square and Kruskal-Wallis tests. We identified 8681 patients with transposition of the great arteries, of whom 1742 (20%) underwent Rashkind procedure. Patients undergoing Rashkind procedure had lower mortality (10% versus 12%, p = 0.021), despite higher median co-morbidities and longer median length of stay. Rashkind procedure was not associated with increased risk of necrotising enterocolitis (1% versus 1%, p = 0.630), but was associated with nearly twice the risk of clinically recognised stroke (1% versus 0%, p = 0.046).
This study represents the largest national analysis of transposition of the great artery patients to date, with a subset treated with Rashkind procedure. Patients not undergoing Rashkind procedure had higher mortality. Rashkind procedure was not associated with increased risk of necrotising enterocolitis, but was associated with twice the risk of stroke.

ABSTRACT: To perform a systematic review and a meta-analysis of the effects of balloon atrial septostomy on peri-operative brain injury in neonates with transposition of the great arteries. We conduct a systematic review of the literature to identify all observational studies that included neonates born with transposition of the great arteries who had peri-operative evidence of brain injury. The search strategy produced three prospective and two retrospective cohort studies investigating the association between balloon atrial septostomy and brain injury totalling 10,108 patients. In two studies, the outcome was represented by the presence of a coded diagnosis of a clinically evident stroke at discharge, whereas in three studies the outcome was represented by the finding of pre-operative brain injury identified by magnetic resonance scans. The overall brain injury rate for neonates who underwent balloon atrial septostomy versus control patients was 60 of 2273 (2.6%) versus 45 of 7835 (0.5%; pooled odds ratio, 1.90; 95% confidence intervals, 0.93-3.89; p = 0.08). A subgroup analysis of the three studies that used pre-operative brain injury as the primary outcome found no significant association between balloon atrial septostomy and brain injury (pooled odds ratio, 2.70; 95% confidence intervals, 0.64-11.33; p = 0.17). Balloon atrial septostomy frequency was 22.4% (2273 of 10,108), with reported rates ranging from 20% to 75%. Our analysis shows that balloon atrial septostomy is not associated with increased odds for peri-operative brain injury. Balloon atrial septostomy should still be used for those patients with significant hypoxaemia, haemodynamic instability, or both.Cardiology in the Young 11/2011; 22(1):1-7.

ABSTRACT: BACKGROUND: Balloon atrial septostomy is a common palliative procedure in neonates with cyanotic congenital heart disease with restricted interatrial blood flow. Despite its advantages, balloon atrial septostomy is not a risk-free procedure and can be associated with numerous complications. The objective of this study is to determine whether the performance of this procedure out-of-hours has a significant impact on the incidence of adverse outcome measures.Methods and ResultsA total of 106 neonates who underwent balloon atrial septostomy between 2004 and 2010 were studied retrospectively. In all, 64 infants had the procedure performed within routine hours (9 am to 6 pm), whereas 42 neonates underwent the procedure out-of-hours (6:01 pm to 8:59 am). Procedure-related complications occurred in 32 infants (30.2%), which included 12 out of 64 (18.8%) infants in the routine-hours group and 20 out of 42 (47.6%) in the out-of-hours group. During further follow-up after surgery and including both major and minor adverse events, seven more infants (10.9%) suffered complications after balloon atrial septostomy in the routine-hours group and four more infants (9.5%) suffered complications in the out-of-hours group. This totalled the complication rate in the routine-hours group to 19 infants (29.7%) and 24 infants (57.1%) in the out-of-hours group (p = 0.001). A higher overall mortality rate was also noted in the out-of-hours group. CONCLUSIONS: Balloon atrial septostomy performed out-of-hours produced higher complication rates as opposed to balloon atrial septostomy performed during routine hours. Only essential cases should be undertaken at night, and all other cases should be deferred to the daytime to limit unnecessary adverse complication.Cardiology in the Young 04/2012; 23(1):1-7.
