[Pseudomonas cepacia endocarditis successfully treated by surgery]
Insights
A pediatric patient with complex congenital heart defects, including coarctation of the aorta, underwent successful surgical repair. Despite developing infective endocarditis, a second surgery resolved the infection and repaired the heart defects, leading to a healthy outcome.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Infectious Diseases
Background:
- Complex congenital heart disease in pediatric patients often requires multi-stage surgical interventions.
- Coarctation of the aorta, ventricular septal defect, and mitral regurgitation present significant surgical challenges.
- Post-operative infective endocarditis is a serious complication in pediatric cardiac surgery.
Observation:
- A 3-year-old female with coarctation of the aorta, ventricular septal defect, and mitral regurgitation underwent initial surgical repair at 7 months.
- Infective endocarditis caused by Pseudomonas cepacia developed 3 months post-surgery, with vegetations noted on the ventricular septum and mitral valve.
- Echocardiography confirmed the presence of vegetations, necessitating further intervention.
Findings:
- Successful management of infective endocarditis with antibiotics followed by a second open-heart surgery.
- The second surgery involved removal of a pledget, reclosure of the ventricular septal defect, and mitral valve replacement.
- The patient achieved a favorable outcome, remaining healthy with no recurrence of endocarditis 2 years post-surgery.
Implications:
- This case highlights the successful management of complex pediatric cardiac defects complicated by infective endocarditis.
- It underscores the importance of timely and aggressive surgical and medical interventions in managing post-operative complications.
- The successful outcome demonstrates the feasibility of re-operative cardiac surgery in pediatric patients with severe infections and structural defects.
Abstract:
The patient was a 3-year-old female with coarctation of the aorta complicated by ventricular septal defect and mitral regurgitation. She underwent surgery for coarctation of the aorta at 7 months of age. We performed direct closure using a pledget for ventricular septal defect and valvoplasty with annuloplasty for mitral regurgitation. Infective endocarditis due to pseudomonas cepacia developed 3 months after the surgery, and echocardiography revealed vegetation in the ventricular septum and anterior leaflet of the mitral valve. After treatment with antibiotics, the second open heart surgery involving removal of the pledget used in the previous operation, reclosure of the ventricular septal defect, and mitral valve replacement was performed. The patient is healthy without recurrence of infective endocarditis 2 years and 2 months after the surgery.
