Summary

Anatomic biventricular correction is feasible in patients with congenital heart disease if their right ventricular end-diastolic volume (RVEDV) increases after initial surgical procedures. This finding offers new possibilities for complex cardiac repair.

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Disease
  • Cardiac Surgery

Background:

  • Initial surgical management for complex congenital heart defects often involves palliative procedures like the bicaval Glenn shunt.
  • These shunts are used to manage reduced right ventricular end-diastolic volume (RVEDV) in young patients.
  • Long-term outcomes require strategies for potential later conversion to a more complete repair.

Observation:

  • A 7-year-old boy with ventricular and atrial septal defects underwent initial repair including a bicaval Glenn shunt due to low RVEDV.
  • At age 15, the patient's RVEDV had increased significantly.
  • This increase in RVEDV enabled a subsequent anatomic biventricular correction by removing the shunt.

Findings:

  • Anatomic biventricular correction was successfully performed after the increase in RVEDV.

  • The feasibility of biventricular repair is directly linked to the postoperative increase in RVEDV.
  • This suggests a potential pathway for achieving complete biventricular physiology in select cases.

    • Implications:

    • This case demonstrates that initial palliative shunts may not preclude later complete biventricular repair.
    • Monitoring RVEDV is crucial for determining the optimal timing and possibility of anatomic biventricular correction.
    • These findings could influence surgical decision-making and long-term management strategies for complex pediatric heart conditions.
