Practicability of Transesophageal Echocardiography in Conscious Patients
Since the initial description by Frazin et al. in 1976 , and in particular since the incorporation of phased array technology into transducers mounted at the tip of a modified gastroscope , transesophageal echocardiography (TEE) has been increasingly used in clinical cardiology — at least in Europe and Japan. In the United States and elsewhere, however, this technique became accepted only slowly over the years; this was due not only to the slight discomfort for the patient associated with a TEE examination but predominantly to safety considerations concerning the introduction and manipulation of the esophageal transducer under optically not controlled conditions in patients with more or less severe heart diseases.
