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 45-year-old man was admitted with a fever that lasted for 2 weeks, dyspnea, and pleuritic chest pain continued for 1 week. Vital signs were as follows: body temperature = 38.5°C, systolic blood pressure = 100/70 mmHg, heart rate = 90/min and, O2 saturation = 85% without oxygenation (90% with nasal oxygen therapy). The ECG showed sinus tachycardia, no significant changes in the ST-segment, low-voltage waves in the limb leads, and QRS alternans. The TTE revealed LVEF of 45%, normal LV size and function without regional wall motion abnormalities, and circumferential pericardial effusion without significant respiratory changes in the mitral and tricuspid valves (Figure ). Lung CT scan showed bilateral GGO suggestive of viral pneumonia (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]), corticosteroid (methylprednisolone 1 mg/kg/day), and remdesivir for COVID-19. However, the pericardial effusion was resolved by the third day after admission. Oxygen saturation increased to 95% after 5 days (without supplemental oxygen) and he was discharged in a satisfying condition. Follow-up of the patient for 3 months showed an LVEF of 45%, mild pericardial effusion, and normal right ventricular size and function.
