This study evaluated an off-pump total cavopulmonary connection technique. The off-pump method showed shorter intensive care unit stays and extubation times, proving beneficial for functional univentricular hearts.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Surgical Innovation

Background:

  • Total cavopulmonary connection (TCPC) is a palliative surgical procedure for complex congenital heart disease.
  • Traditional TCPC often requires cardiopulmonary bypass, carrying associated risks.
  • Evaluating alternative surgical techniques is crucial for improving patient outcomes.

Purpose of the Study:

  • To assess the feasibility and early outcomes of an off-pump technique for total cavopulmonary connection.
  • To compare the results of off-pump TCPC with conventional cardiopulmonary bypass techniques.

Main Methods:

  • Retrospective analysis of 16 patients undergoing off-pump TCPC between May 2000 and June 2004.
  • Comparison with a control group of 17 patients who had TCPC with cardiopulmonary bypass.

  • Evaluation of preoperative and postoperative oxygen saturation, pulmonary arterial pressure, and clinical outcomes.

    • Main Results:

    • Two early postoperative deaths occurred in the off-pump group.
    • Chylothorax and reoperations for fenestration were observed in a subset of off-pump patients.
    • Survivors in the off-pump group achieved significantly improved oxygen saturation (95% +/- 3%) and shorter extubation and ICU stays compared to the bypass group.

    Conclusions:

    • The off-pump total cavopulmonary connection is technically feasible and associated with improved early recovery metrics.
    • This technique may offer advantages in managing patients with functional univentricular hearts.
    • Further research is needed to fully understand the long-term implications of this surgical approach.
