A rare aortico-right ventricular tunnel in an infant was successfully repaired. This complex congenital heart defect was diagnosed using echocardiography and confirmed with cardiac catheterization, with a positive 5-year follow-up.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Aortico-right ventricular tunnel is a rare congenital heart anomaly.
  • This condition involves abnormal communication between the aorta and the right ventricle.
  • Accurate preoperative diagnosis is crucial for successful surgical planning.

Observation:

  • A case of an infant diagnosed with an aortico-right ventricular tunnel is presented.
  • The tunnel originated independently from the left coronary ostium, above the sinus of Valsalva.
  • Two-dimensional Doppler color echocardiography and cardiac catheterization were used for diagnosis.

Findings:

  • Surgical repair was performed using patch closure from within the tunnel.
  • The procedure was conducted under deep hypothermia.

  • The operation was successful, with no immediate complications.

    • Implications:

    • This case demonstrates the feasibility of surgical correction for this rare anomaly.
    • Successful repair ensures improved long-term outcomes for affected infants.
    • The findings highlight the importance of advanced imaging and catheterization in diagnosing complex congenital heart defects.
