A 34-year-old woman was admitted with complaint of losing consciousness and she had also been suffering from fever and headache for six consecutive days. Vital signs were as follows: body temperature = 36.7°C, systolic blood pressure = 80/60 mmHg, heart rate = 114/min, and O2 saturation = 82% without oxygenation. Also, the GCS score equaled 8. The ECG monitoring revealed ventricular tachycardia (Figure ); so, the direct current (DC) shock was administered and the patient was intubated. Echocardiography showed normal LV and RV size, moderate tricuspid and mitral regurgitation, systolic pulmonary artery pressure of 30 mmHg, and LVEF of 30%. The chest CT scan illustrated bilateral GGO and basal consolidations (Figure ) as well as the patient had a positive nasal and oropharyngeal PCR test for COVID-19. The patient received broad-spectrum antibiotics (meropenem [500 mg q8 h for 5 days] and doxycycline [200 mg/day]), high-dose corticosteroid (methylprednisolone 1 g/day), and remdesivir for COVID-19. The patient was discharged after 3 weeks with LVEF of 40%–45% and normal cardiac biomarkers. Follow-up of the patient for 3 months showed an LVEF of 45%–50%.
A 16-year-old boy was admitted with fever, diarrhea, and dry cough that had occurred for 1 week before admission. The first evaluation of the patient at the time of admission was as follows: low blood pressure (80/60 mmHg), non-palpable pulse, and cyanosis, oxygen saturation was 85% without oxygenation, and the body temperature was 38°C. The ECG showed normal sinus rhythm with diffuse anterior ST-segment elevations in precordial leads (Figure ). Rapid improvement of the ECG abnormality resulted from carrying out vasopressors and intubation. Echocardiography represented left ventricular wall thickness, LVEF of 20%–25% with generalized hypokinesis, normal RV size (and function), and dilated inferior vena cava. Moreover, valvular structure and function were normal. The patient had a positive nasal and oropharyngeal PCR test for COVID-19, and the lung CT scan disclosed GGO (Figure ).\nThe patient received IVIG (1 g/kg), broad-spectrum antibiotics (meropenem [500 mg] and doxycycline [200 mg/day]), high-dose corticosteroid (methylprednisolone 1 g/day), and remdesivir for COVID-19. Nonetheless, the patient died the next day after admission due to sudden bradycardia, hypotension, and cardiac arrest.
