Anterior vs Lateral Lung Fields in Heart Failure

Do we need both?

Suspected acute heart failure is a great reason to use point-of-care ultrasound. It can tell you in seconds if this patient is up to their neck in pulmonary edema. Knowing that interstitial edema is more common in dependent areas of the lung, one would think that the lateral areas of the lung fields would be most sensitive for the diagnosis. Likewise, if there is enough pulmonary edema to fill up the anterior lung fields, this theoretically should be pretty specific. But is this actually true?! These authors investigate the issue. https://www.ncbi.nlm.nih.gov/pubmed/30665807
