RESUMEN
OBJECTIVES: Previous cross-sectional studies have demonstrated obesity rates in children with CHD and the general paediatric population. We reviewed longitudinal data to identify factors predisposing to the development of obesity in children, hypothesising that age may be an important risk factor for body mass index growth.Study designRetrospective electronic health records were reviewed in all 5-20-year-old CHD patients seen between 2011 and 2015, and in age-, sex-, and race/ethnicity-matched controls. Subjects were stratified into aged cohorts of 5-10, 11-15, and 15-20. Annualised change in body mass index percentile (BMI%) over this period was compared using paired Student's t-test. Linear regression analysis was performed with the CHD population. RESULTS: A total of 223 CHD and 223 matched controls met the inclusion criteria for analysis. Prevalence of combined overweight/obesity did not differ significantly between the CHD cohort (24.6-25.8%) and matched controls (23.3-29.1%). Univariate analysis demonstrated a significant difference of BMI% change in the age cohort of 5-10 (CHD +4.1%/year, control +1.7%/year, p=0.04), in male sex (CHD +1.8%/year, control -0.3%/year, p=0.01), and status-post surgery (CHD 2.03%/year versus control 0.37%, p=0.02). Linear regression analysis within the CHD subgroup demonstrated that age 5-10 years (+4.80%/year, p<0.001) and status-post surgery (+3.11%/year, p=0.013) were associated with increased BMI% growth. CONCLUSIONS: Prevalence rates of overweight/obesity did not differ between children with CHD and general paediatric population over a 5-year period. Longitudinal data suggest that CHD patients in the age cohort 5-10 and status-post surgery may be at increased risk of BMI% growth relative to peers with structurally normal hearts.

Obesity may associate with greater cardiovascular risk in adults with congenital heart disease (ACHD) than in the general population. As ACHD often have exercise limitations, they may be uniquely predisposed to obesity. Nevertheless, obesity prevalence in ACHD, compared with the general population, has not been quantified in a large US cohort. Hence, we sought to determine the prevalence of obesity (30 ≤ body mass index <40) and morbid obesity (body mass index ≥40), in a large cohort of ACHD, compared with matched controls. Retrospective analysis was thus performed on all ACHD seen in an academic system in 2013. CHD severity was classified as simple, complex, or unclassified, using recently published criteria. A control group without CHD was randomly generated matching for age, gender, and race/ethnicity; 1,451 ACHD met inclusion criteria; 59.5% of ACHD were overweight to morbidly obese. Compared with controls, ACHD had similar prevalence of overweight (odds ratio [OR] 1.04, 95% confidence interval [CI] 0.89 to 1.22, p = 0.63) and obesity (OR 0.96, 95% CI 0.81 to 1.15, p = 0.69) but lower prevalence of morbid obesity (OR 0.24, 95% CI 0.16 to 0.34, p <0.001). These relationships were not attenuated by adjustment for CHD severity. In conclusion, ACHD are at equal risk as their matched peers to be overweight and obese. This is the largest study of obesity in US ACHD and the highest reported obesity prevalence in ACHD to date. As obesity is associated with significant cardiovascular risk, our findings indicate a need for improved lifestyle counseling in patients with CHD of all ages.

BACKGROUND: Anomalous aortic origin of a coronary artery from the wrong Sinus of Valsalva (AAOCA) is a rare congenital anomaly and is associated with sudden cardiac death. Morphologic features considered to be "high risk" are significant luminal narrowing, acute coronary angulation at its origin, intramural course, and long interarterial course. A consistent approach for characterization of these features is lacking. METHODS: A retrospective single-center review of all patients diagnosed with AAOCA using echocardiogram and computed tomography (CT)/magnetic resonance imaging (MRI) studies was performed. Twenty-nine patients were identified (25 using CT and 4 using MRI) with subsequent three-dimensional data sets. The MRI data sets lacked adequate resolution and were excluded. Twenty-five patients (median age 15.1, range 10-39.5 years, 72% male) were further analyzed using echocardiogram and CT. Morphologic assessment focused on luminal stenosis, coronary angulation, and interarterial length. Additional morphologic features focusing on cross-sectional area and degree of ellipticity were also assessed. RESULTS: Echocardiography tended to yield smaller measurements compared to CT and had poor interobserver reproducibility for measurements pertaining to the narrowest proximal and distal coronary segments. Computed tomography showed good inter-/intraobserver reproducibility for the same. Agreement between both modalities for coronary angulation at its origin was excellent. There was good agreement for measurements of interarterial length between echocardiography and CT, but echocardiography had superior reproducibility. Assessment of luminal cross-sectional area and elliptical shape by CT had excellent inter-/intraobserver reproducibility. CONCLUSION: The combination of echocardiography and CT characterizes morphologic features of anomalous origin of the coronary artery more reliably than either modality alone.

OBJECTIVE: Critical congenital heart disease is increasingly recognized prenatally. Following the diagnosis, families are advised to deliver in a facility where neonatal cardiac interventions are available. We studied the safety of transport of neonates who had been prenatally diagnosed with duct-dependent congenital heart lesions. METHODS: We performed a retrospective chart review of all fetuses diagnosed with duct-dependent congenital heart disease in our fetal program between 2007 and 2011. Demographic data, dose of prostaglandin infusion, respiratory status, blood gas data, as well as complications of the transport were collected. RESULTS: Twenty-nine neonates qualified for inclusion in the study. Ten were intubated (7 electively) prior to the transport. One of these required intervention for desaturation during the transport. One of the 19 unintubated patients required emergent intubation during the transport. Thus, the overall rate of incidents was 6.9%. All 4 patients who developed apnea requiring intubation did so within 1 h of starting prostaglandin. CONCLUSIONS: Elective postnatal transport of neonates prenatally diagnosed with duct-dependent congenital heart lesions is safe. Prophylactic intubation of these infants may not be necessary. It would be advantageous to schedule the elective transport an hour after starting prostaglandin or later.
