Summary
This case report details successful surgical repair of supravalvular aortic stenosis and pulmonary artery branch stenosis in a Williams syndrome patient. The intervention resolved all symptoms, demonstrating effective treatment for complex cardiovascular issues in this genetic disorder.
Area of Science:
- Cardiovascular Surgery
- Medical Genetics
- Pediatric Cardiology
Background:
- Williams syndrome is a genetic disorder associated with supravalvular aortic stenosis.
- Cardiovascular abnormalities are common in Williams syndrome, necessitating specialized surgical interventions.
- This case highlights a complex presentation involving both aortic and pulmonary artery stenosis.
Observation:
- A 45-year-old woman with Williams syndrome presented with progressive symptoms due to supravalvular stenosis of the ascending aorta.
- Further examination revealed multiple stenoses in the branches of the pulmonary artery.
- Notably, the patient lacked typical facial features and cognitive impairment associated with Williams syndrome.
Findings:
- Surgical intervention involved extracorporeal circulation for aortic repair using a Dacron flap.
- Reimplantation and reconstruction of stenosed aortic arch branches were performed.
- The surgical procedure was uneventful, with complete symptom resolution at four months post-operation.
Implications:
- This case demonstrates the feasibility and efficacy of surgical correction for complex supravalvular aortic stenosis and pulmonary artery branch stenosis in Williams syndrome.
- It underscores the importance of comprehensive cardiovascular evaluation in Williams syndrome patients, even in the absence of typical phenotypic features.
- Successful surgical outcomes can significantly improve quality of life for individuals with complex cardiovascular manifestations of Williams syndrome.
