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 dysfunction may be present and echocardiography is warranted.[2] Echocardiography is valuable for the risk stratification of PE among hemodynamically unstable patients.[1] The presence of right ventricular dysfunction is a predictor of early death among patients with PE.[3]

Echocardiography

  • Echocardiography may 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}}

  • In another study, a value of less than 1.0 for right-to-left ventricular diameter was shown to have a 100% negative predictive value for an uneventful outcome (95% CI: 94.3%, 100%).[7]
  • In addition to the above, echocardiography can also be useful in patients with right heart thromboemboli or with a patent foramen ovale. These patients have a higher rate of complications and a higher mortality rate.[8][9]
