Summary
Coronary ostial stenosis, a serious complication after aortic valve replacement, was successfully treated with urgent revascularization. This case highlights effective management for this rare but life-threatening condition.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Complications
- Interventional Cardiology
Background:
- Aortic valve replacement (AVR) is a common procedure.
- Coronary ostial stenosis (COS) is a rare but severe complication post-AVR.
- COS can lead to myocardial ischemia and infarction.
Observation:
- A patient presented with symptoms of coronary insufficiency 4 months post-AVR.
- Coronary angiography revealed 99% stenosis of the left main stem.
- Intraoperative findings showed a dense fibrous reaction in the aortic root affecting the left coronary ostium.
Findings:
- Urgent revascularization was performed for the critical left main stem stenosis.
- The fibrous reaction compressing the left coronary ostium was identified as the cause.
- The patient experienced an uneventful recovery and remained asymptomatic post-procedure.
Implications:
- This case underscores the importance of considering COS in patients with ischemic symptoms after AVR.
- Prompt diagnosis and surgical intervention are crucial for favorable outcomes.
- Understanding the pathogenetic mechanisms of COS post-AVR can guide preventative strategies.
