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.

In Utero Presentation of Left Ventricular Aneurysm.

Congenital left ventricular aneurysm, pseudoaneurysm, and diverticulum are rare entities. These diagnoses can be made pre- and/or postnatally. Although these entities overlap clinically and morphologically, important distinctions can allow for accurate diagnoses. Appropriate diagnosis can be imperative for risk stratification and guidance of prenatal and postnatal management. The case described in the present report highlights a challenging case of a fetal left ventricular aneurysm, management during the prenatal and postnatal periods, and important differentiating features from a ventricular diverticulum and pseudoaneurysm.

A Prospective Study Evaluating the Effects of SSRI Exposure on Cardiac Size and Function in Newborns.

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are antidepressants prescribed in 10% of pregnancies in the USA. We have previously shown in preclinical studies that sertraline exposure impacts cardiomyocyte development, leading to reductions in left ventricular size and cardiac function. OBJECTIVES: We hypothesized that in utero SSRI exposure will lead to reduced left ventricular dimensions and cardiac function on echocardiography immediately after birth. METHODS: Twenty term infants with and 21 term infants without in utero exposure to SSRIs underwent echocardiograms to assess cardiac size and function. The exclusion criteria for infants were prematurity, small or large for gestational age, any respiratory or cardiovascular support needed after birth, and any major congenital malformation. RESULTS: Infants exposed to in utero SSRIs had significantly reduced right ventricular dimensions in the diastole (controls 1.0 cm [0.86, 1.20], SSRI 0.89 cm [0.730, 1.05], p = 0.03), and left ventricular lengths in the diastole and systole (diastole: controls 3.4 cm [3.25, 3.65], SSRI 3.25 cm [3.10, 3.45], p = 0.03; systole: controls 2.9 cm [2.65, 3.05], SSRI 2.6 cm [2.50, 2.85], p = 0.01). No differences were observed in cardiac function. Importantly, there were no differences in maternal conditions or infant birth weight, body surface area, or gestational age. CONCLUSIONS: Our findings suggest an association between in utero exposure to SSRIs and ventricular size in infants. Given the increasing use of SSRIs during pregnancy and the importance of early life programming on future cardiovascular health, larger studies need to be completed to determine if in utero SSRI exposure impacts ventricular size.

Tissue Plasminogen Activator Use in Children: Bleeding Complications and Thrombus Resolution.

OBJECTIVE: To review our institutional experience with tissue plasminogen activator (tPA) to determine outcomes related to bleeding complications and thrombus resolution. STUDY DESIGN: We performed a retrospective review of all patients who received systemic tPA for thrombolysis. Data points included location of thrombus, initial and maximum tPA dose, and duration of tPA. The primary endpoint was bleeding complication. RESULTS: Between 2005 and 2014, 46 patients received systemic tPA for thrombolysis: 17 (37%) were patients with a primary cardiac diagnosis, there were 17 (37%) hematology/oncology patients, and 12 (26%) patients with noncardiac, nonhematology/oncology diagnoses. The indication for tPA was central venous thrombus (n = 23), pulmonary artery thrombus (n = 9), and cardiac or aortic thrombus (n = 14). Bleeding complications occurred in 15 patients (33%). Median initial tPA dose in the bleeding complication group was 0.10 mg/kg/h vs 0.03 mg/kg/h in the group without bleeding complication group (P = .01). Cardiac patients experienced more bleeding complications (P = .01). Multivariate analysis indicated that dose of tPA (P = .01) and diagnostic category (P < .01) were associated with bleeding complication. Complete thrombus resolution occurred in 21 patients, partial in 10 patients, and no resolution in 15 patients. Complete resolution of thrombus was not associated with diagnosis, thrombus location, tPA dose, or duration. CONCLUSIONS: Cardiac patients appear to be at highest risk of bleeding complication; bleeding complications were associated with higher doses of tPA, and cardiac patients were the cohort who received the highest doses of tPA. Higher tPA doses are associated with increased risk of bleeding complication but are not associated with successful thrombus resolution.
