A new ultra-miniaturized pocket ultrasound device (PUD) may be suited to this specific setting. Therefore, we aimed to compare the diagnostic ability of an ultra-miniaturized ultrasound device (Vscan\u2122, GE Healthcare, Wauwatosa, WI) and of a conventional high-quality echocardiography system (Vivid S5\u2122, GE Healthcare) for a cardiac focused ultrasonography in patients admitted to the emergency department.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Methods<\/jats:title>\n                        <jats:p>During 4 months, patients admitted to our emergency department and requiring transthoracic echocardiography (TTE) were included in this single-center, prospective and observational study. Patients underwent TTE using a PUD and a conventional echocardiography system. Each examination was performed independently by a physician experienced in echocardiography, unaware of the results found by the alternative device. During the focused cardiac echocardiography, the following parameters were assessed: global cardiac systolic function, identification of ventricular enlargement or hypertrophy, assessment for pericardial effusion and estimation of the size and the respiratory changes of the inferior vena cava (IVC) diameter.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Results<\/jats:title>\n                        <jats:p>One hundred fifty-one (151) patients were analyzed. With the tested PUD, the image quality was sufficient to perform focused cardiac ultrasonography in all patients. Examination using PUD adequately qualified with a very good agreement global left ventricular systolic dysfunction (\u03ba = 0.87; 95%CI: 0.76-0.97), severe right ventricular dilation (\u03ba = 0.87; 95%CI: 0.71-1.00), inferior vena cava dilation (\u03ba = 0.90; 95%CI: 0.80-1.00), respiratory-induced variations in inferior vena cava size in spontaneous breathing (\u03ba = 0.84; 95%CI: 0.71-0.98), pericardial effusion (\u03ba = 0.75; 95%CI: 0.55-0.95) and compressive pericardial effusion (\u03ba = 1.00; 95%CI: 1.00-1.00).<\/jats:p>\n                     <\/jats:sec><jats:sec>\n
