Observational Study
Impact of device selection and clip duration on lung ultrasound assessment in patients with heart failure.
Pulmonary edema is a common sign of heart failure and can be quantified by counting vertical artifacts (B-lines) on lung ultrasound (LUS). The primary aim of this study was to compare a pocket size ultrasound device to high-end ultrasound systems on the measured number of B-lines. We also compared the impact of different-length ultrasound clips on the measured number of B-lines. ⋯ Our findings suggest significant differences based on LUS clip duration rather than the type of ultrasound device used, with respect to the number of B-lines detectable in patients with heart failure. These factors should be considered in the design and reporting of LUS studies and in longitudinal assessments of heart failure patients.

The aim of this study was to assess the outcomes, incidental findings, recommendations, and adherence to recommendations on computed tomography angiography (CTA) studies obtained in the emergency department (ED) to evaluate for aortic dissection. ⋯ Computed tomography angiography is useful in detecting aortic pathology. However, emergency physicians should be aware of the potential for clinically significant incidental findings and recommendations. Adherence to recommendations was limited, and future research could investigate mechanisms to improve compliance.
