Management of an infected pseudoaneurysm following an aortoventriculoplasty
1Department of Cardiac Surgery, Royal Hospital for Sick Children, Glasgow, Scotland, UK.
Insights
A child developed prosthetic valve endocarditis and a false aneurysm after aortoventriculoplasty. Surgical management of this complex cardiac infection and vascular complication is discussed.
Area of Science:
- Cardiology
- Cardiac Surgery
- Infectious Diseases
Background:
- Prosthetic valve endocarditis (PVE) is a serious complication following cardiac valve replacement.
- Aortoventriculoplasty is a surgical procedure to treat certain congenital heart defects.
- False aneurysms can arise as a complication of cardiac surgery and infection.
Observation:
- An 11-year-old patient presented with PVE and infected prosthetic/pericardial patches 6 months post-aortoventriculoplasty.
- Diagnostic angiography identified a false aneurysm connecting the ascending aorta and right ventricular outflow tract.
Findings:
- The patient exhibited a complex presentation of prosthetic valve endocarditis with contiguous patch infection.
- A significant false aneurysm was identified, posing a risk of rupture and hemodynamic compromise.
- The anatomical communication of the false aneurysm with major cardiac structures highlighted the surgical challenge.
Implications:
- This case underscores the importance of vigilant monitoring for PVE and its complications after complex cardiac procedures.
- Successful surgical management requires a thorough understanding of the infectious and structural abnormalities.
- The report contributes to the literature on managing rare but life-threatening complications in pediatric cardiac surgery.
Abstract:
An 11-year-old child developed prosthetic valve endocarditis with associated infection of the prosthetic and pericardial patches 6 months following an aortoventriculoplasty. Angiography revealed an associated false aneurysm which communicated with both the ascending aorta and the right ventricular outflow tract. This report discusses the surgical management of this patient.
