Echocardiography is not recommended as a routine imaging test to diagnose suspected pulmonary embolism. However, it is useful for identifying patients with pulmonary embolism who may have a poor prognosis. It can be used for rapid and accurate risk assessment. Moderate or severe right ventricular hypokinesis, persistent pulmonary hypertension, a patent foramen ovale, and free-floating right-heart thrombus are echocardiographic markers that identify patients at risk for death or recurrent thromboembolism. Such patients warrant consideration for thrombolysis or embolectomy. Serial imaging of right ventricular function can help physicians monitor the effect of treatment and judge whether the selected management strategy is successful. Further research will clarify and define more precisely the utility and limitations of echocardiography in the management of pulmonary embolism.

Left ventricular hypertrophy is associated with significant excess mortality and morbidity. The study and treatment of this condition, in particular the prognostic implications of changes in left ventricular mass, require an accurate, safe, and reproducible method of measurement. Cardiovascular magnetic resonance is a suitable tool for this purpose, and this review assesses the technique in comparison with others and examines the clinical and research implications of the improved reproducibility.
