Summary
A complex case of infective endocarditis required aortic root replacement and coronary artery bypass grafting. Subsequent graft stenosis and pseudoaneurysm were successfully treated with urgent surgery and homograft redo replacement.
Area of Science:
- Cardiovascular Surgery
- Infective Endocarditis Management
- Complex Coronary Artery Bypass Grafting
Background:
- Severe infective endocarditis necessitated aortic root replacement with a homograft.
- Concomitant saphenous vein grafting to the left anterior descending artery was performed.
Observation:
- The patient developed angina due to proximal vein graft anastomosis stenosis.
- A significant 2-cm pseudoaneurysm was identified at the anastomosis site.
Findings:
- Urgent coronary artery bypass surgery via left thoracotomy successfully managed the complex lesion.
- Redo replacement of the aortic homograft was performed following the bypass surgery.
Implications:
- This case highlights a successful management strategy for complex post-endocarditis surgical complications.
- Understanding the mechanism and treatment basis is crucial for similar challenging cardiovascular cases.
