Summary

Biplane transesophageal echocardiography (bi-TEE) offers superior cardiac imaging compared to monoplane TEE. This advanced technique improves visualization of the left ventricle, right heart structures, atria, and aorta, enhancing diagnostic accuracy.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Echocardiography

Background:

  • Two-dimensional echocardiography (echo 2D) with Doppler assesses heart function.
  • Transthoracic echocardiography (TEE) is limited in 10-15% of patients due to body habitus or thoracic abnormalities.
  • Monoplane TEE (m-TEE) provided single-plane imaging, overcoming some TEE limitations.

Purpose of the Study:

  • To evaluate the diagnostic value of biplane transesophageal echocardiography (bi-TEE).
  • To compare bi-TEE with the existing monoplane TEE (m-TEE) technique.

Main Methods:

  • Sixty patients (19-78 years) with heart and aorta conditions underwent bi-TEE.
  • Examinations utilized an Aloka SSD-870 with a biplane probe (45 patients) or a matrix probe (15 patients).

  • Standard projections were used for cardiac and aortic assessment.

    • Main Results:

    • Bi-TEE offers improved left ventricular and apex visualization.
    • It enables comprehensive assessment of the right heart, including valves and great vessels.
    • Bi-TEE provides detailed imaging of atrial structures and the thoracic aorta, particularly the ascending aorta.

    Conclusions:

    • Biplane transesophageal echocardiography significantly enhances cardiac and aortic visualization compared to monoplane TEE.
    • The technique offers a more complete evaluation of cardiac structures, including the right heart and atria.
    • Bi-TEE is a valuable diagnostic tool for complex cardiovascular assessments.
