Arterial switch operation with autologous sinus tube for transposition of great vessels with single coronary.
Signal observed for novel surgical technique in complex transposition of the great arteries repair. Evidence suggests that autologous coronary sinus tube construction can provide a viable alternative to standard button transfer in neonates with single coronary artery origin, with successful outcomes including normal left ventricular function and stable valve regurgitation at discharge. Worth noting the patient achieved discharge on post-operative day 10 with preserved coronary patency despite complex anatomy.
The patient was discharged on post-operative Day 10 with normal left ventricular function, stable mild aortic and pulmonary valve regurgitation, and laminar antegrade flow in...
Relevance: Directly addresses arterial switch operation for transposition of the great arteries (dx-tga), a primary diagnosis in the profile. Describes surgical technique and perioperative management in a pediatric patient with complex coronary anatomy.

Machine learning-based risk stratification identifies heart failure with preserved ejection fraction as an independent predictor of adverse outcomes in hypertrophic cardiomyopathy.
Evidence suggests heart failure with preserved ejection fraction (HFpEF) occurs in 47.8% of hypertrophic cardiomyopathy patients and independently predicts worse outcomes. Signal observed for machine learning models achieving strong discrimination (AUC = 0.856) in risk prediction, with HFpEF status and BNP identified as dominant risk factors. Worth noting the non-linear relationship between BNP levels and adverse events, with accelerating risk at higher concentrations.
Integrating H₂FPEF score-based risk subgrouping, non-linear biomarker modeling, and interpretable machine learning enhances personalized risk stratification and may, pending external validation, inform precision management strategies...
Relevance: Related to heart failure phenotyping research interest, demonstrating advanced risk stratification approaches, though focused on adult HCM rather than pediatric congenital heart disease.

Cost-Effectiveness of Therapies for Heart Failure in Brazil: A Systematic Review.
Evidence suggests several heart failure interventions demonstrate economic attractiveness in Brazil's healthcare system, with spironolactone and eplerenone showing cost-effectiveness ratios of Int$ 7,955/QALY and Int$ 6,459/QALY respectively. Signal observed for newer therapies like dapagliflozin and sacubitril-valsartan also meeting cost-effectiveness thresholds. Worth noting that most technologies were evaluated in single studies, limiting robust comparative analyses.
Expanding national economic studies is necessary to support access to effective therapies while maintaining the sustainability of the health system.
Relevance: Related to heart failure research interest and provides economic perspective on therapeutic options, though focused on adult populations and Brazilian healthcare context rather than pediatric-specific considerations.

High Burden of Cardiac Abnormalities in Adults with HIV in Ethiopia: A Multicenter Cross-Sectional Study.
Signal observed for high prevalence of cardiac abnormalities (42.1%) in Ethiopian adults with HIV, including dilated cardiomyopathy, pulmonary hypertension, and systolic dysfunction. Evidence suggests dilated cardiomyopathy was independently associated with CD4 < 200 cells/mm³, antiretroviral therapy-naïve status, and BMI < 18.5 kg/m². Worth noting that most cardiac disease was asymptomatic, suggesting potential benefit of targeted screening in high-risk populations.
Integrating targeted echocardiographic screening into routine HIV care, prioritizing patients with advanced immunosuppression, lack of ART, or malnutrition, may improve early detection and management.
Relevance: Related to heart failure and pulmonary hypertension research interests, providing insights into cardiac disease mechanisms and screening approaches, though in adult HIV population rather than pediatric congenital heart disease.
