Background. SARS-CoV-2 is a new strain of the coronavirus family that emerged by the end of 2019 and led to the unpreceded COVID-19 pandemic. The virus affects multiple organs simultaneously and leads to a high rate of morbidity and mortality in all age groups. The cardiovascular system is one of the major affected organ systems. Various mechanisms including direct myocardial injury contribute to the cardiac manifestations of COVID-19 patients. Methods. We performed a comprehensive and updated search on the cardiac manifestations of COVID-19. Our search included laboratory and imaging evaluations. In addition, we added a unique section on the effect of SARS-CoV-2 on the cardiovascular system in the pediatric population. Results. COVID-19 might have an effect on the cardiovascular system at various levels leading to myocardial ischemia, arrhythmia, heart failure, myocarditis, and multisystem inflammatory syndrome in children. The incidence of cardiovascular complications varies among patients. This paper also provides a comprehensive summary of all the reported pediatric cases with cardiac manifestations. Conclusion. Multidisciplinary teams are crucial for adequate management of patients with COVID-19 regardless of age. Timely diagnosis is critical in reducing mortality.

COVID-19 患者的心脏表现：关注儿科人群

背景。SARS-CoV-2 是冠状病毒家族的一种新毒株，于 2019 年底出现并导致了史无前例的 COVID-19 大流行。该病毒同时影响多个器官，并导致所有年龄组的高发病率和死亡率。心血管系统是主要受影响的器官系统之一。包括直接心肌损伤在内的各种机制促成了 COVID-19 患者的心脏表现。方法。我们对 COVID-19 的心脏表现进行了全面更新的搜索。我们的搜索包括实验室和成像评估。此外，我们增加了一个关于 SARS-CoV-2 对儿科人群心血管系统影响的独特部分。结果. COVID-19 可能对心血管系统产生不同程度的影响，导致儿童出现心肌缺血、心律失常、心力衰竭、心肌炎和多系统炎症综合征。心血管并发症的发生率因患者而异。本文还对所有报告的有心脏表现的儿科病例进行了全面总结。结论。无论年龄大小，多学科团队对于充分管理 COVID-19 患者至关重要。及时诊断对于降低死亡率至关重要。
