RESUMO
Coronavirus disease 2019 (COVID-19) vaccine-induced cardiac injury has recently emerged as a major public health concern around the globe. There are reported cases of COVID-19 vaccine-induced myocarditis, but they are generally extremely rare and mild. In contrast, COVID-19 infection can cause acute cardiac injury with poor prognosis and high mortality rates. Herein, we describe the difference in patients' presentation by comparing two cases of myocarditis. One after contracting COVID-19 virus infection with a severe clinical course, and the other patient developed myocarditis post-COVID-19 vaccine.
RESUMO
Intracavitary right coronary arteries (RCAs) are uncommon (incidence of 0.09%-0.1%), having previously been reported nearly exclusively in autopsy series. However, more recently this entity has been detected prospectively by noninvasive cardiac computed tomography. Because many interventional procedures, including pacemaker placement and atrial flutter ablation, may be influenced by the presence of an intracavitary RCA, this entity is important to recognize. We report two cases of intracavitary right coronary artery discovered prospectively by cardiac computed tomography. In one of these cases, interventional management was altered based on our findings.
