Anomalous aortic origin of the right coronary artery. Central Message We sought to establish evidence-based guidelines for the management anomalous aortic origin of a coronary artery. Perspective Anomalous aortic origin of a coronary artery is associated with sudden cardiac death. Although the risk for any single affected individual is small, the loss of an otherwise healthy person is particularly devastating. Surgical and interventional therapies have been developed that appear to be protective but these therapies carry risks. The challenge is identifying those individuals at such risk.

By use of cardiac MRI and CT, the anomalous course of round coronary ostia was confirmed and visualized in a pediatric cohort with intraseptal anomalous left coronary artery. The data provide the basis for understanding the benign clinical course and showing that surgery is unnecessary for this coronary anomaly.

In the medium-term after AAOCA repair, cardiac-type symptoms frequently persist and morbidity is common, but these do not impair QOL. The significance of these findings in the long-term is unknown and warrants continued follow-up.

Cardiac MRI with virtual angioscopy is an important tool for evaluating anomalous coronary anatomy, myocardial function, and ischemia and should be considered for initial and postoperative assessment of children with anomalous coronary arteries.

Anomalous aortic origin of a coronary artery (AAOCA) occurs when both coronary arteries arise from the same aortic sinus from a single ostium or two separate ostia. While most coronary anomalies are benign, the two most common subtypes that predispose to sudden cardiac death in the young are interarterial anomalous right coronary artery and interarterial anomalous left coronary artery. Practitioners face many challenges with AAOCA. Diagnosing patients may be difficult because children and adolescents are often asymptomatic and first presentation may be sudden death or sudden cardiac arrest. Risk stratification is also challenging as determining which unique characteristics place the child at highest risk of sudden death has not been adequately delineated and ischemic testing may give false negative results. Last, there is significant variability in decision making regarding management of youth with AAOCA. Future research is needed to help determine the best way to identify at-risk children and which treatment is the safest and most efficacious.

Treatment strategies may include exercise restriction or surgical repair. Management decisions should be based on a complete understanding of the risk for SCD because of anomalous coronary arteries. Future directions should focus on better methods to risk stratify these pediatric patients.

Physical activity (PA) decreased and sedentary behavior (SB) increased in the pediatric population during the Coronavirus Disease 2019 (COVID-19) pandemic. We examined the effects of PA and SB on cardiopulmonary exercise performance in children, adolescents and young adults both with and without underling cardiac disease, and hypothesized that there will be a change in aerobic and physical working capacity during the pandemic. This was a single-center retrospective longitudinal cohort study in patients age 6–22 years who underwent serial maximal cardiopulmonary exercise stress testing before and during the COVID-19 pandemic. Metabolic variables were obtained; PA and SB data were extracted from clinic notes. A total of 122 patients (60% male) underwent serial exercise testing with a median age of 14 years at the first CPET. Predicted peak aerobic capacity significantly decreased among both females and males during the pandemic, even after adjusting for changes in somatic growth. There was no significant change in physical working capacity during the pandemic. Patients who were more aerobically fit experienced a greater decrease in aerobic capacity during the pandemic compared to those less fit. In conclusion, cardiopulmonary exercise performance, notably aerobic activity, decreased during the COVID-19 pandemic in children, adolescents and young adults compared to pre-pandemic values. This decline was most notable in those with the highest pre-pandemic aerobic capacity values and was independent of somatic growth or changes in BMI. This study has public health implications and demonstrates the importance of PA on overall cardiovascular health.
