Background: Lung ultrasound (LUS) is emerging as a useful diagnostic tool for several lung pathologies. Some studies have found its accuracy in diagnosing pulmonary edema surpasses that of chest x-ray (CXR) but the available evidence is conflicting. CXR currently receives a Class I recommendation by the AHA in the evaluation of decompensated heart failure. Given [...]

Background: Lung ultrasound (LUS) is emerging as a useful diagnostic tool for several lung pathologies including pulmonary edema. The number of sonographic B-lines on LUS has been used as a test to detect pulmonary congestion in patients with chronic heart failure. However, its ability to detect elevated left-sided filling pressures relative to accepted noninvasive measure [...]
