Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are significant public health concerns around the world. Despite decreasing incidence, there is still a significant disease burden, especially in developing nations. This review provides background on the history of ARF, its pathology and treatment, and the current reported worldwide incidence of ARF and prevalence of RHD.

This study demonstrated a measurable gain in knowledge about vascular rings and pulmonary artery slings with the addition of 3D printed models of the defects. Future applications of this teaching modality could extend to other congenital cardiac lesions and different learners.

Incorporation of 3D printed models into lectures about CHD imparts a greater acute level of understanding, both subjective and objective, for pediatric and combined pediatric/emergency medicine residents. There does not seem to be an added benefit for understanding ventricular septal defects, but there is for tetralogy of Fallot, likely due to increased complexity of the lesion and difficulty visualizing spatial relationships in CHD with multiple components.

The aim of the current study is to investigate hospitalization outcomes of COVID-19 positive children and adults with moderate or severe congenital heart disease to children and adults without congenital heart disease. Retrospective review using the Vizient Clinical Data Base for admissions of patients with an ICD-10 code for COVID-19 from April 2020 to March 2021. Admissions with COVID-19 and with and without moderate or severe congenital heart disease (CHD) were stratified into pediatric (< 18 years) and adult (≥ 18 years) and hospital outcomes were compared. There were 9478 pediatric COVID-19 admissions, 160 (1.7%) with CHD, and 658,230 adult COVID-19 admissions, 389 (0.06%) with CHD. Pediatric admissions with COVID-19 and CHD were younger (1 vs 11 years), had longer length of stay (22 vs 6 days), higher complication rates (6.9 vs 1.1%), higher mortality rates (3.8, 0.8%), and higher costs ($54,619 vs 10,731; p < 0.001 for all). Adult admissions with COVID-19 and CHD were younger (53 vs 64 years, p < 0.001), had longer length of stay (12 vs 9 days, p < 0.001), higher complication rates (8 vs 4.8%, p = 0.003), and higher costs ($23,551 vs 13,311, p < 0.001). This appears to be the first study to report the increased hospital morbidities and costs for patients with CHD affected by COVID-19. Our hope is that these findings will help counsel patients moving forward during the pandemic.

Ventricular stress testing by RVE is feasible, safe and identifies a subgroup of Fontan patients with occult DD. Higher baseline EDP and longer duration of Fontan circulation are associated with worse diastolic function. Future work is necessary to better understand the aetiology, associations and clinical implications of occult DD in Fontan survivors.
