Summary
Severe aortic regurgitation due to a quadricuspid aortic valve was successfully treated by suturing a separated accessory cusp to the non-coronary cusp, achieving a competent valve. Postoperative assessment showed only trivial aortic regurgitation.
Area of Science:
- Cardiology
- Cardiac Surgery
- Valvular Heart Disease
Background:
- Quadricuspid aortic valve is a rare congenital anomaly.
- Severe aortic regurgitation necessitates timely intervention.
- Accurate surgical technique is crucial for valve repair.
Observation:
- A 58-year-old male presented with severe aortic regurgitation.
- Intraoperative findings revealed a quadricuspid aortic valve with a separated small accessory cusp from the non-coronary cusp.
Findings:
- The non-coronary cusp and accessory cusp were surgically sutured together.
- This procedure aimed to create a single, competent cusp with an effective height of 8 mm.
- Postoperative day 7 assessment demonstrated trivial aortic regurgitation.
Implications:
- This case highlights a successful valve repair technique for complex quadricuspid aortic valve anomalies.
- Surgical repair can effectively restore aortic valve competence and improve patient outcomes.
- Further research into standardized repair techniques for quadricuspid valves is warranted.
