Dwyer KH, et al. - Researchers here evaluated the combined accuracy of right heart strain on focused cardiac ultrasound (FOCUS) and deep vein thrombosis (DVT) on compression ultrasound (CUS) for identification of centrally located pulmonary embolism (PE) diagnosed on computed tomography pulmonary angiography (CTPA). In this study, emergency physician-performed bedside ultrasound, with the sensitivity of 100%, seemed sufficient to exclude the presence of centrally located PE. Furthermore, when DVT was identified, several patients with PE qualified for early anticoagulation. They recommended further research to determine whether these patients ultimately require CTPA given identical treatment algorithms in the absence of RV strain or biomarker elevation.
