Color Doppler transesophageal echocardiography in detection of massive pulmonary embolism: Is pulmonary angiography always the gold standard?

Abstract

In this article, the potential value of color Doppler in improving diagnostic accuracy of transesophageal echocardiography (TEE) in patients with incomplete obstruction of large pulmonary vessels is illustrated. We present an unusual case of massive pulmonary embolism that was unequivocally detected by color Doppler TEE both before and after pulmonary angiography, which failed to demonstrate filling defects in the pulmonary artery.
