Overview

Routine echocardiography in patients with suspected pulmonary embolism (PE) is not required.[1] In fact, the majority of patients with PE have a normal echocardiography.[1] However if elevations in the cardiac troponins or brain natriuretic peptide are present, then acute right ventricular (RV) dysfunction may be present and echocardiography is warranted.[2] Echocardiography is also valuable for the evaluation of hemodynamically unstable patients with acute dyspnea, right heart failure, or syncope who are suspected to have PE.[1] The presence of right ventricular dysfunction is a predictor of early death among patients with PE.[3] When evidence of RV dysfunction is present, PE is risk stratified into submassive PE or massive PE depending on the absence or presence of hypotension respectively.[4][5]

Echocardiography

  • Echocardiography may also show akinesia of the mid-free wall but normal apical motion of the right ventricle. This is referred to as the McConnell sign. The sensitivity and specificity of the McConnell sign for the diagnosis of acute PE are 77% and 94% respectively.[6]

Shown below is an echocardiogram that demonstrates McConnell sign: {{#ev:youtube|Tklaxe-kPrk}}
