Health Equity and Policy Considerations for Pediatric and Adult Congenital Heart Disease Care among Minoritized Populations in the United States.

Achieving health equity in populations with congenital heart disease (CHD) requires recognizing existing disparities throughout the lifespan that negatively and disproportionately impact specific groups of individuals. These disparities occur at individual, institutional, or system levels and often result in increased morbidity and mortality for marginalized or racially minoritized populations (population subgroups (e.g., ethnic, racial, social, religious) with differential power compared to those deemed to hold the majority power in the population). Creating actionable strategies and solutions to address these health disparities in patients with CHD requires critically examining multilevel factors and health policies that continue to drive health inequities, including varying social determinants of health (SDOH), systemic inequities, and structural racism. In this comprehensive review article, we focus on health equity solutions and health policy considerations for minoritized and marginalized populations with CHD throughout their lifespan in the United States. We review unique challenges that these populations may face and strategies for mitigating disparities in lifelong CHD care. We assess ways to deliver culturally competent CHD care and to help lower-health-literacy populations navigate CHD care. Finally, we review system-level health policies that impact reimbursement and research funding, as well as institutional policies that impact leadership diversity and representation in the workforce.

Relation of Right Ventricular Dilation After Pulmonary Valve Replacement to Outcomes in Patients With Repaired Tetralogy of Fallot.

The rationale for timing of pulmonary valve replacement (PVR) in patients with repaired Tetralogy of Fallot (rTOF) has focused on pre-PVR threshold values of indexed right ventricular end-diastolic volume (RVEDVi) that lead to normalization of right ventricular (RV) size after valve implantation. The goal of this study was to determine whether persistent RV dilation after PVR is associated with adverse clinical outcomes. Subjects with rTOF who underwent PVR and had a cardiac magnetic resonance (CMR) exam after valve implantation at a single center from 2001 to 2017 were included. The composite clinical outcome after PVR included: death, aborted sudden cardiac death, sustained ventricular tachycardia (VT), or NYHA class ≥3. In 189 rTOF subjects, the mean age at PVR was 23.5 ± 11.7 years, median follow-up was 6.0 years (IQR 3.4 to 8.7), and the primary outcome occurred in 14 subjects (7%). The 5- and 10-year event-free rates were 97% and 91%, respectively. Post-PVR RVEDVi was not associated with the composite outcome (p = 0.59). Independent predictors of the outcome were older age at PVR (hazard ratios [HR] 1.06; 95% confidence interval [CI] 1.02 to 1.11; p = 0.004), post-PVR lower RV ejection fraction (HR 0.91; 95% CI 0.86 to 0.97; p = 0.002), and post-PVR atrial tachyarrhythmia (HR 7.60, 95% CI 1.65 to 35.05, p = 0.009). Our study shows that post-PVR RV dilation as measured by CMR-derived RVEDVi was not associated with the composite adverse clinical outcome in this cohort. These findings challenge the validity of current guidelines for PVR, which are based on pre-procedural threshold values of RVEDVi aimed at achieving normal post-procedural RV volumes.

Disseminated histoplasmosis mimicking secondary syphilis.

A 34-year-old, HIV-positive man living in Texas presented with a 2-week history of fever, malaise, myalgias, oral ulcers, and papules on his chest, back, face, and extremities, including the palms. Initially secondary syphilis was suspected. However, RPR was negative. Histopathologic examination revealed a lymphocytic infiltrate with numerous intra-histiocytic fungal organisms. GMS and PAS stains were positive, consistent with the diagnosis of histoplasmosis. We report a case of disseminated histoplasmosis clinically mimicking secondary syphilis.
