Area of Science:

  • Cardiology
  • Medical Imaging
  • Diagnostic Techniques

Background:

  • Contrast echocardiography (CE) is underutilized despite advancements in imaging techniques.
  • Reevaluation of CE's utility and indications is necessary in modern cardiology.
  • Color flow Doppler has become a standard, potentially overshadowing CE.

Purpose of the Study:

  • To reassess the clinical usefulness and indications for contrast echocardiography (CE).
  • To determine the role of CE in diagnosing specific cardiac conditions.
  • To evaluate CE's effectiveness in the era of advanced Doppler imaging.

Main Methods:

  • Analysis of 7823 consecutive echocardiographic studies.
  • Identification of studies where contrast echocardiography (CE) was applied (638 cases).

  • Review of indications including right ventricular overload, pulmonary hypertension, and patent foramen ovale (PFO) screening.

    • Main Results:

    • CE was used in 8% of studies.
    • CE aided in diagnosing right ventricular overload (379 patients) and pulmonary hypertension (321 patients).
    • CE improved Doppler signals for tricuspid regurgitation and right heart dimension quantification, and was crucial for PFO detection (259 patients screened).

    Conclusions:

    • Contrast echocardiography (CE) remains a valuable diagnostic tool.
    • CE is indicated for evaluating right ventricular overload and pulmonary hypertension.
    • CE is particularly essential for the detection of patent foramen ovale (PFO).
