Summary

Automated border detection (ABD) offers new insights into right ventricular function. While validated for global assessment, its clinical value in diagnosing and managing right ventricular dysfunction requires further determination.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Echocardiography

Background:

  • Quantitative evaluation of right ventricular (RV) function is complex due to its intricate geometry.
  • Traditional methods struggle with simple geometric assumptions for RV assessment.
  • Automated border detection (ABD) is established for left ventricular function but less so for RV.

Purpose of the Study:

  • To review studies validating ABD for objective global RV function assessment.
  • To detail current clinical uses and limitations of ABD techniques for RV.
  • To explore potential applications of color kinesis for regional RV function.

Main Methods:

  • Review of studies validating Automated Border Detection (ABD) for RV function.
  • Analysis of acoustic quantification and color kinesis for RV assessment.

  • Examination of technical guidelines and limitations of ABD.

    • Main Results:

    • ABD techniques provide novel insights into right atrial and RV systolic/diastolic properties.
    • Acoustic quantification is validated for global RV function.
    • Color kinesis shows potential for objective regional RV function assessment.

    Conclusions:

    • ABD offers objective assessment of global RV function, complementing existing methods.
    • Further research is needed to establish the clinical utility of ABD and color kinesis in RV dysfunction diagnosis and management.
    • The full clinical value of these advanced imaging techniques for RV disease requires determination.
