Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Medical Device Innovation

Background:

  • Accurate hemodynamic monitoring is crucial during pediatric open-heart surgery.
  • Left atrial pressure (LAP) measurement can be challenging in pediatric patients undergoing complex procedures.
  • Existing monitoring techniques may have limitations in pediatric cardiac surgery.

Purpose of the Study:

  • To evaluate the feasibility and safety of a newly designed 4 French gauge (FG) double-lumen catheter for simultaneous left atrial and central venous pressure monitoring.
  • To assess the catheter's performance during pediatric open-heart surgery, including insertion, positioning, and removal.

Main Methods:

  • A novel 4 FG double-lumen catheter with a unique port design was tested in five pediatric patients.
  • The catheter was inserted percutaneously and advanced into the left atrium across the interatrial septum during cardiopulmonary bypass.
  • Simultaneous monitoring of left atrial pressure and central venous pressure was performed.

Main Results:

  • The novel catheter allowed successful and continuous monitoring of left atrial pressure in all pediatric patients.
  • Central venous pressure was effectively monitored using the second port when positioned in the superior vena cava.
  • Catheter removal was straightforward and uneventful, with no reported complications.

Conclusions:

  • The newly designed 4 FG double-lumen catheter is a safe and effective tool for monitoring left atrial pressure in pediatric patients during open-heart surgery.
  • This device offers a viable solution for improved hemodynamic assessment in complex pediatric cardiac procedures.
  • Further studies may explore its utility in a broader range of pediatric cardiac interventions.
