BackgroundAmong patients who die from pulmonary embolus (PE), approximately two-thirds succumb within an hour of presentation. Computed tomography can provide a definitive diagnosis but is associated with practical limitations. Echocardiography can increase diagnostic certainty of PE by visualizing signs of acute right ventricular (RV) strain. This case highlights a potentially lethal finding associated with PE and the role of clinician-performed bedside echocardiography in the timely management of this disease.ObjectiveTo describe a case of PE-in-transit diagnosed by clinician-performed focused echocardiography.Case ReportA 78-year-old man with lymphoma presented to the Emergency Department with shortness of breath. His blood pressure was 95/53 mm Hg; his oxygen saturation was 84% on room air. A focused echocardiogram showed a highly mobile elongated mass traversing the right atrium and right ventricle, consistent with a PE-in-transit. Anticoagulation was initiated and Cardiovascular Surgery was consulted for emergent thrombectomy. Minutes after reviewing the ultrasound with the surgeons, the patient was transported to the operating room. Just before surgery, the patient had a cardiac arrest. Exploration of his heart failed to reveal thrombus; however, extensive clot burden was removed from the pulmonary arteries, with subsequent return of spontaneous circulation.ConclusionThe clinician performed a focused echocardiogram to evaluate the cause of the patient's critical state. PE-in-transit, a rare entity associated with large PEs, was identified, which obviated the need for further diagnostic evaluation and led to immediate aggressive therapy. Increased familiarity with the uses of bedside sonography in the evaluation of shock and respiratory distress may allow clinicians to become more proficient in managing these patients.Copyright © 2013 Elsevier Inc.
