A rare right ventricular outflow tract pseudoaneurysm developed early after surgery for a complex heart defect. Emergency repair was required due to critical symptoms like low cardiac output and syncope.

Area of Science:

  • Cardiovascular Surgery
  • Congenital Heart Disease
  • Surgical Complications

Background:

  • Right ventricular outflow tract (RVOT) pseudoaneurysms are rare, potentially life-threatening lesions.
  • They often arise as a complication of cardiac surgery involving right ventriculotomy.
  • These pseudoaneurysms can lead to serious issues including airway compression and rupture.

Observation:

  • A patient developed an RVOT pseudoaneurysm shortly after surgical repair of atrio-ventricular septal defect with tetralogy of Fallot.
  • The pseudoaneurysm progressively enlarged, causing significant clinical deterioration.
  • The patient presented with low cardiac output and recurrent syncopal attacks.

Findings:

  • Early diagnosis and prompt surgical intervention are crucial for managing RVOT pseudoaneurysms.

  • Successful emergency surgical repair was performed in this complex case.
  • This case highlights the importance of vigilance for rare complications post-cardiac surgery.

    • Implications:

    • This case underscores the need for heightened awareness of RVOT pseudoaneurysms in post-cardiac surgery patients.
    • Early recognition and management can prevent catastrophic outcomes such as rupture.
    • Further research into preventative strategies and optimal surgical timing may be warranted.
