Summary

Congenital absence of the left pericardium, often found during cardiac surgery, necessitates careful attention to the left phrenic nerve and diaphragm due to associated defects. Early recognition prevents surgical complications.

Area of Science:

  • Cardiovascular Surgery
  • Anatomical Variations
  • Congenital Abnormalities

Background:

  • The pericardium, a protective sac around the heart, can rarely be congenitally absent on the left side.
  • This rare anomaly may be discovered incidentally during cardiovascular procedures.
  • Associated anatomical variations can pose surgical risks.

Observation:

  • A case of coronary artery bypass grafting revealed an incidental finding of congenitally absent left pericardium.
  • Associated anatomical anomalies included a defect in the left hemidiaphragm and an aberrant course of the left phrenic nerve.
  • These findings were noted during the surgical procedure, highlighting a potential for intraoperative complications.

Findings:

  • Congenital absence of the left pericardium can present with associated defects, notably in the left hemidiaphragm.

  • The left phrenic nerve may follow an abnormal anatomical path in individuals with this condition.
  • Surgical dissection requires meticulous attention to the phrenic nerve's proximity to the heart and diaphragm.

    • Implications:

    • Recognition of absent left pericardium during cardiac surgery is crucial for patient safety.
    • Careful identification and management of the left phrenic nerve are essential to prevent iatrogenic injury.
    • Closure of associated diaphragmatic defects is necessary to prevent potential herniation and associated complications.
