Summary

Real-time three-dimensional transthoracic echocardiography (3D-TTE) offers valuable insights into cardiac anatomy and function, especially for complex structural heart disease. This advanced imaging technique provides additive information beyond conventional 2D-TTE for improved diagnosis and assessment.

Area of Science:

  • Cardiovascular Imaging
  • Echocardiography
  • Medical Technology

Background:

  • Complex cardiac anatomy necessitates advanced imaging for accurate interpretation.
  • Real-time three-dimensional transthoracic echocardiography (3D-TTE) is an emerging technique for cardiac assessment.
  • Evaluating 3D-TTE's feasibility and efficacy in structural heart disease is crucial.

Purpose of the Study:

  • To assess the feasibility and efficacy of real-time 3D-TTE.
  • To comprehensively evaluate cardiac anatomy, physiology, pathomorphology, and pathophysiology.
  • To compare 3D-TTE with conventional 2D-TTE in patients with structural heart disease.

Main Methods:

  • 152 patients with structural heart disease underwent both 2D-TTE and real-time 3D-TTE.

  • Evaluated rheumatic and non-rheumatic valvular heart disease, and congenital heart defects.
  • Assessed left and right ventricular function using dedicated software.

    • Main Results:

    • 3D-TTE mitral valve area assessment is comparable to 2D-TTE, with added detail on leaflet anatomy.
    • 3D-TTE provides additive value for enface views of atrial septal defects and tricuspid valve assessment.
    • Objective assessment of ventricular volumes and regurgitation vena contracta area is enhanced by 3D-TTE.

    Conclusions:

    • Real-time 3D-TTE is clinically feasible for evaluating structural heart disease.
    • 3D-TTE offers significant additive value over 2D-TTE for specific cardiac structures.
    • Further validation of quantitative measurements from 3D-TTE is warranted.
