Risk Factors of Long-Term Sequelae After Transcatheter Closure of Perimembranous Ventricular Septal Defect in Young Children.

BACKGROUND: Complications arising from transcatheter closure of perimembranous ventricular septal defects (pmVSD) in children, such as residual shunts and aortic regurgitation (AR), have been observed. However, the associated risk factors remain unclear. This study identified risk factors linked with residual shunts and AR following transcatheter closure of pmVSD in children aged 2-12 years.Methods and Results: The medical records of 63 children with pmVSD and a pulmonary-to-systemic blood flow ratio <2.0 who underwent transcatheter closure between 2011 and 2018 were analyzed with a minimum 3-year follow-up. The success rate of transcatheter closure was 98.4%, with no emergency surgery, permanent high-degree atrioventricular block, or mortality. Defects ≥4.5 mm had significantly higher odds of persistent residual shunt (odds ratio [OR] 6.85; P=0.03). The use of an oversize device (≥1.5 mm) showed a trend towards reducing residual shunts (OR 0.23; P=0.06). Age <4 years (OR 27.38; 95% confidence interval [CI] 2.33-321.68) and perimembranous outlet-type VSD (OR 11.94, 95% CI 1.10-129.81) were independent risk factors for AR progression after closure. CONCLUSIONS: Careful attention is crucial for pmVSDs ≥4.5 mm to prevent persistent residual shunts in transcatheter closure. Assessing AR risk, particularly in children aged <4 years, is essential while considering the benefits of pmVSD closure.

Kawasaki disease in children with Bacillus Calmette-Guérin scar reactivity: Focus on coronary outcomes.

BACKGROUND: /Purpose: Reactivity at the Bacillus Calmette-Guérin (BCG) scar is a pathognomonic feature of Kawasaki disease (KD). However, its value in predicting KD outcomes has not been emphasized. This study explored the clinical significance of BCG scar redness with respect to coronary artery outcomes. METHODS: This retrospective study collected data on children with KD from 13 hospitals in Taiwan during 2019-2021. Children with KD were categorized into four groups based on the KD type and BCG scar reactivity. Risk factors of coronary artery abnormalities (CAA) were analyzed in all groups. RESULTS: BCG scar redness occurred in 49% of 388 children with KD. BCG scar redness was associated with younger age, early intravenous immunoglobulin (IVIG) treatment, hypoalbuminemia, and CAA at the first echocardiogram (p < 0.01). BCG scar redness (RR 0.56) and pyuria (RR 2.61) were independent predictors of any CAA within 1 month (p < 0.05). Moreover, pyuria (RR 5.85, p < 0.05) in children with complete KD plus BCG scar redness was associated with CAA at 2-3 months; first IVIG resistance (RR 15.2) and neutrophil levels ≥80% (RR 8.37) in children with complete KD plus BCG scar non-redness were associated with CAA at 2-3 months (p < 0.05). We failed to detect any significant risk factors of CAA at 2-3 months in children with incomplete KD. CONCLUSION: BCG scar reactivity contributes to diverse clinical features in KD. It can be effectively applied to determine the risk factors of any CAA within 1 month and CAA at 2-3 months.

Growth In ACA-Compliant Marketplace Enrollment And Spending Risk Changes During The COVID-19 Pandemic.

In 2020 the COVID-19 pandemic caused millions to lose their jobs and, consequently, their employer-sponsored health insurance. Enacted in 2010, the Affordable Care Act (ACA) created safeguards for such events by expanding Medicaid coverage and establishing Marketplaces through which people could purchase health insurance. Using a novel national data set with information on ACA-compliant individual insurance plans, we found large increases in Marketplace enrollment in 2020 compared with 2019 but with varying percentage increases and spending risk implications across states. States that did not expand Medicaid had enrollment and spending risk increases. States that expanded Medicaid but did not relax 2020 Marketplace enrollment criteria also had spending risk increases. In contrast, states that expanded Medicaid and relaxed 2020 enrollment criteria experienced enrollment increases without spending risk changes. The findings are reassuring with respect to the ability of Marketplaces to buffer employment shocks, but they also provide cautionary signals that risks and premiums could begin to rise either in the absence of Medicaid expansion or when Marketplace enrollment is constrained.
