RESUMO
Objectives: The heart is one of the organs frequently affected by the multisystem inflammatory syndrome in children (MIS-C), associated with severe acute respiratory syndrome coronavirus 2 infection. Cardiac involvement in patients with MIS-C was evaluated with physical examination findings, biochemical test, and cardiological imaging tests. We reported the degree of cardiac involvement in patients with MIS-C. Methods: In this retrospective study, the complaints, physical examination, and cardiac findings of patients with MIS-C were evaluated. Results: Sixteen patients (four males and 12 females) with MIS-C were included in the study. The median age was 6 (5-17) years. In patients, palpitations (6%), chest pain (12%), ECG changes (50%), valve insufficiency (50%), low ejection fraction (6%), coronary dilatation (6%), troponin (38%), and d-dimer (88%) elevation were detected. One patient died. Valve insufficiency persisted in 5 (31%) patients. Conclusion: Severe cardiac involvement can be seen in MIS-C patients. Due to its serious effects on mortality and morbidity, cardiac involvement should be evaluated with cardiac imaging tools such as echocardiography and ECG in all MIS-C patients.
