    A 79-year-old female patient presented to the emergency unit with cough and severe shortness of breath. Due to a bilateral multilobular ground glass density result from thoracic tomography, the patient was admitted to intensive care with the preliminary diagnosis of corona virus-2019 (COVID-19), and a continuous positive airway pressure was applied. A polymerase chain reaction (PCR) test was performed, and treatment with hydroxychloroquine and azithromycin was initiated. At the same time, the patient with an arterial blood pressure of 190/100 mm/hg was administered with diuretic treatment to reduce lung congestion. The follow-up computed tomography of the patient showed rapid recovery, and ground glass appearances had completely resolved. The PCR was negative and the patient was diagnosed with acute lung edema. The treatment was prescribed, and the patient was discharged from the hospital. Thoracic tomography findings are useful in early period for COVID-19 diagnosis; however, it may show similar results as other diseases that cause respiratory failure and lead to misleading interpretations.

    Role ofPoint-of-CareLung and Inferior Vena Cava Ultrasound in Clinical Decisions for Patients Presenting to the Emergency Department With Symptoms of Acute Decompensated Heart Failure
    (2020) Hacialiogullari, Fakiye; Yilmaz, Fevzi; Yilmaz, Aykut; Sonmez, Bedriye Muge; Demir, Tayfun Anil; Karadas, Mehmet Akif; Duyan, Murat; Ayaz, Gizem; Ozdemir, Metin; 0000-0001-5841-2591; 0000-0002-4719-2535; 32865243; AAJ-3607-2021; AAJ-1600-2021
    Objectives This prospective study was performed to evaluate the diagnostic role of point-of-care lung ultrasound (LUS) and inferior vena cava (IVC) ultrasound in patients with acute decompensated heart failure (ADHF). Methods A prospective cohort study was conducted between January 2018 and November 2018 on patients with a diagnosis of ADHF in the emergency department (ED). On admission, LUS findings, inspiratory and expiratory IVC diameters, and the inferior vena cava collapsibility index (IVCCI) were obtained. After therapeutic interventions, third-hour changes in LUS and the IVC index and the treatment response were assessed. Results Eighty patients were enrolled. Forty-six (58%) patients had an ejection fraction (EF) greater than 40%, and 34 (42%) had an EF of less than 40%. Significant differences were detected between the admission and third-hour inspiratory IVC diameter, expiratory IVC diameter, and IVCCI (P= .001). There was no correlation between the EF and inspiratory IVC diameter (r= -0.03;P= .976), expiratory IVC diameter (r= -109;P= .336), or IVCCI (r= -0.72;P= .523) and between the B-type natriuretic peptide level and inspiratory IVC diameter (r= -0.58;P= .610), expiratory IVC diameter (r= -0.33;P= .774), or IVCCI (r= -0.78;P= .493) either. A comparison of admission and third-hour numbers of B-lines on LUS imaging showed a significant decrease in the number of B-lines in all zones at the end of 3 hours (P= .001). A significant difference existed between the hospitalized and discharged patients with respect to IVC diameters and number of B-lines. Conclusions In the ED setting, an assessment of B-lines and measurement of IVC diameters are better markers than the B-type natriuretic peptide level, EF, or chest x-ray for diagnosis of ADHF and can be used to make decisions for hospitalization or discharge from the ED.
