Current role of echocardiography in patients with pulmonary embolism

Pulmonary embolism is a major health problem. Clinical presentation may vary from cardiovascular emergency with high mortality risk to mild or atypical illness, and the diagnosis is not always easy. However, the timeliness of diagnosis and prognostic stratification are crucial because immediate treatment and thromboembolic prophylaxis are highly effective. Echocardiography can play a key role in pulmonary embolism regarding different aspects: diagnosis, risk stratification, and follow-up but sometimes it is not properly used. Therefore, it is important for a physician to know exactly how to utilize echocardiography in pulmonary embolism. The purpose of this paper is to review the role of echocardiography as part of the diagnosis, management and follow-up of acute pulmonary embolism in the light of current literature.
