Spontaneous Coronary Artery Dissection Following SARS-CoV-2-Associated Multisystem Inflammatory Syndrome.

Spontaneous coronary artery dissection (SCAD) is an underdiagnosed cause of acute coronary syndrome, myocardial infarction, and sudden cardiac death. During the coronavirus disease 2019 (COVID-19) pandemic, a multisystem inflammatory syndrome (MIS) emerged that is incompletely understood. While the involvement of numerous organ systems has been described, the potential cardiovascular manifestations, such as myocarditis, arterial thrombosis, or SCAD, are particularly worrisome. Here, we present a case of MIS that was preceded by an unremarkable case of COVID-19 and followed by the development of SCAD. This case highlights the importance of furthering our understanding of the potential sequelae of COVID-19 and of the potential relationship between SCAD and MIS.
