Summary
This case study details a male patient with Williams syndrome and supravalvular aortic stenosis. Surgical intervention successfully corrected the aortic stenosis, improving the patient's cardiac function.
Area of Science:
- Cardiology
- Genetics
- Pediatric Surgery
Background:
- Williams syndrome is a genetic disorder associated with cardiovascular abnormalities, including supravalvular aortic stenosis.
- Supravalvular aortic stenosis presents as a narrowing of the aorta just above the aortic valve.
- Early diagnosis and monitoring are crucial for managing associated cardiac complications.
Observation:
- A male patient with Williams syndrome presented with a harsh systolic heart murmur at age 5.
- Diagnosis revealed supravalvular aortic stenosis with a pressure gradient of 35 mmHg.
- Progressive stenosis led to an 80 mmHg gradient by age 11.
Findings:
- Surgical intervention involved extended aortoplasty using a Hemashield graft prosthesis.
- Postoperative cardiac catheterization demonstrated complete resolution of the pressure gradient.
- The successful surgical outcome highlights the efficacy of intervention for this condition.
Implications:
- This case underscores the importance of cardiac surveillance in patients with Williams syndrome.
- Surgical repair of supravalvular aortic stenosis can effectively restore normal aortic blood flow.
- Timely surgical management can prevent long-term cardiovascular complications in affected children.
