[Role of transesophageal echocardiography in the diagnosis of pulmonary embolism].

The authors report a 72 year-old woman presenting with severe shock after ilio-femoral artery bypass surgery. The transesophageal echocardiography allowed the diagnosis of an unsuspected massive right pulmonary artery embolism. This case emphasizes the role of this procedure for the early bedside diagnosis of massive pulmonary embolism, especially in critically ill patients who require urgent therapeutic interventions.
