Transesophageal two-dimensional echocardiography: comparison of ultrasonic and anatomic sections.

Conventional 2-dimensional echocardiography has become a well-established tool for evaluating cardiovascular diseases. Recent introduction of 2-dimensional transesophageal echocardiography has widened the ultrasonic examination possibilities of the heart and great arteries. The 6 standard transesophageal transducer positions that have proved representative and of diagnostic value are described. To facilitate structure identification and interpretation of anatomic relations, transesophageal recordings were compared with corresponding anatomic sections.
