Area of Science:

  • Medical Imaging
  • Interventional Cardiology
  • Pediatric Cardiology

Background:

  • Transhepatic access is an alternative for cardiac catheterization when conventional routes fail.
  • Ultrasound guidance for transhepatic access has not been previously reported.
  • Establishing safe and effective venous access is crucial for cardiac procedures.

Purpose of the Study:

  • To investigate the efficacy and safety of ultrasound guidance for transhepatic access in cardiac catheterization.
  • To evaluate the feasibility of this technique in a pediatric population.
  • To assess complication rates associated with ultrasound-guided transhepatic access.

Main Methods:

  • Retrospective chart review of patients undergoing transhepatic cardiac catheterization at Duke University Medical Center.

  • Inclusion criteria: all patients who underwent transhepatic cardiac catheterization.
  • Data collected: patient demographics, procedure indications, catheterization type, and complications.

    • Main Results:

    • Eight pediatric patients underwent 12 transhepatic cardiac catheterizations.
    • Median age was 5.3 years; median weight was 18.7 kg.
    • Seven diagnostic and five interventional procedures were performed with no reported complications.

    Conclusions:

    • Ultrasound guidance is a safe and effective method for transhepatic venous access during cardiac catheterization.
    • This technique provides a reliable option for complex pediatric cardiac interventions.
    • Further research can explore broader applications and long-term outcomes.
