This case study details a successful surgical repair of a chronic left ventricular false aneurysm in a 47-year-old woman, 8 years after initial Staphylococcus aureus infection. The patient recovered well despite a temporary postoperative neurological complication.
Area of Science:
- Cardiology
- Cardiac Surgery
- Infectious Diseases
Background:
- A 47-year-old woman presented with a chronic left ventricular false aneurysm.
- The aneurysm stemmed from Staphylococcus aureus septicemia and endocarditis 8 years prior.
- Delayed surgical intervention was necessitated by the development of heart failure (NYHA III).
Observation:
- The patient underwent surgery via median sternotomy with cardiopulmonary bypass.
- A large, calcified left ventricular false aneurysm was identified and dissected free from adhesions.
- Complete excision of the aneurysm and closure of the defect with non-absorbable sutures were performed.
Findings:
- The surgical procedure for left ventricular false aneurysm excision was technically successful.
- Postoperatively, the patient experienced an epileptic attack with transient left hemiplegia.
- Neurological symptoms resolved within 48 hours, and the patient was discharged in good condition.
Implications:
- This case highlights the successful management of a rare complication of infective endocarditis.
- It underscores the importance of timely surgical intervention for left ventricular aneurysms, even after a significant delay.
- The case demonstrates the feasibility of complete aneurysmectomy and repair in complex scenarios.
