Although COVID-19 is a disease consisting of mostly upper and lower respiratory symptoms, a subset of patients develop cardiac sequelae including myocarditis and pericarditis. For these patients, a standardized set of diagnostic imaging techniques and treatments has not been established. While there have been numerous case reports on this topic, there are few reviews that evaluate the effectiveness of different treatment modalities with a significant number of cases. We reviewed 146 cases of patients (ages ranging from 2 months old to mid 80 s) obtained from searches on PubMed, Google Scholar, and several case report journals. ECG abnormalities, elevated inflammatory markers, and reduced left ventricular ejection fraction were most associated with COVID-19 myocarditis. While classic symptoms of COVID-19 include upper respiratory symptoms, a subset of patients diagnosed with COVID-19 displayed no signs of respiratory disease at all. In 22% of cases, cardiac sequelae was not present until after the patient recovered from COVID-19. Steroids were given in 57.5% of cases. Cardiac MRI was used in 40.4% of cases for diagnosis of myocarditis. Of all the patients who were treated with ECMO, 82.1% of these patients were able to fully recover. The use of cardiac MRI and transthoracic echocardiogram for diagnosis of COVID-19 myocarditis should be heavily considered in any patient with COVID-19 infection. ECMO, IVIG, steroids, and anticoagulants should also be heavily considered. A randomized controlled trial should be conducted to better associate treatments with outcomes. [ABSTRACT FROM AUTHOR]

Background: Multisystem inflammatory syndrome (MIS), which develops after a past covid-19 infection. MIS can be described in different tissue inflammation, including the heart, lung, kidney, brain, skin, eye, and or gastrointestinal organs at the presence of COVID-19. Initially, MIS was described in Europe in children infected with SARS-CoV-2, then it was recently seen in the USA in 2020. MIS is a rare but serious disease condition associated with COVID-19 that can affect children (MIS-C) and adults (MIS-A). Case presentation: A 44-year-old male who showed MIS-A in 59-day after his first covid-19 contact history. The patient presented to our emergency department with complaints of high fever, nausea, weakness, redness of the eyes, headache, and joint pain. On the second day of his hospitalization, a maculopapular skin lesion was seen in most of the skin. His fever could not be controlled even given paracetamol and broad effective antibiotics. His clinical, radiological, and laboratory findings showed that he had MIS-A. The patient was given intravenous pulse methylprednisolone and intravenous immunoglobulin (IVIG). These treatments, then, resulted in improvement of his clinical conditions, including fever and skin lesions, on the second day of the treatment. The patient was discharged in 14 days after the treatment. Conclusion: This report indicated that diagnosis and treatment of MIS-A could result in reducing patient morbidity and mortality.
