Area of Science:

  • Cardiology
  • Medical Imaging
  • Interventional Procedures

Background:

  • Pericardiocentesis is a procedure to drain fluid from the pericardial sac.
  • Accurate needle placement is crucial for successful and safe pericardiocentesis.
  • Limitations in visualizing needle tip during the procedure can lead to complications.

Purpose of the Study:

  • To evaluate the clinical utility of two-dimensional contrast echocardiography in guiding pericardiocentesis.
  • To assess the safety and efficacy of using contrast echocardiography for needle localization.

Main Methods:

  • Investigated 20 patients undergoing pericardiocentesis for pericardial effusion.
  • Utilized agitated saline injection via the exploring needle to generate contrast echoes.

Related Experiment Videos

  • Observed echo patterns to confirm needle position within the pericardium.

    • Main Results:

    • Contrast echocardiography successfully visualized needle position in all 20 patients.
    • 18 out of 20 patients (90%) had pericardiocentesis performed smoothly.
    • Two patients experienced needle misplacement (right atrium, right ventricle), managed with surgery or repeat echo-guided procedure.

    Conclusions:

    • Two-dimensional contrast echocardiography is a valuable tool for pericardiocentesis.
    • It enhances needle localization, contributing to safer and more successful fluid aspiration.
    • This technique can improve outcomes in managing pericardial effusion.
