Several techniques for the surgical correction of congenital supravalvular aortic stenosis have been devised. We describe the step-by-step surgical approach of a slide aortoplasty to correct localized supravalvular aortic stenosis in a 3-year-old child with Williams syndrome.

An increasing number of procedures over the past two decades for aortic stenosis (AS) reflects the combination of an aging population and less invasive transcatheter options. As a result, the hemodynamics of the aortic valve (AV) have gained renewed interest to understand its behavior and to optimize patient selection. We studied the hemodynamic relationship between pressure loss (ΔP) and transvalvular flow (Q) of the normal AV as well as the impact of a variable supravalvular stenosis.

Background: An effective prognostic nomogram to predict the prognosis for supravalvular aortic stenosis (SVAS) patients is lacking.
Methods: A multi-center retrospective study of consecutive SVAS patients with surgery between 2002 and 2020 was conducted. Patients underwent McGoon repairs, Doty repairs, and other repairs.

Article Synopsis
- Shone complex (SC) is a rare congenital heart disease involving four obstructive lesions in the left side of the heart, making up 0.6-0.7% of CHD cases.
- A 4-week-old male neonate with SC presented severe respiratory distress and related symptoms, leading to a diagnosis that included multiple heart issues and a successful surgical intervention at five months.
- Early detection through echocardiography and multidisciplinary care is crucial for effective management and improved patient outcomes in SC cases.
Prenatal diagnosis, ultrasound findings and pregnancy outcome of 7q11.23 deletion and duplication syndromes: what are the fetal features?

The Genetics Laboratory, Longgang District maternity & Child Healthcare Hospital of Shenzhen City (Longgang Maternity and Child Institute of Shantou University Medical College), Shenzhen, Guangdong, China.
Article Synopsis
- The study aimed to analyze ultrasound findings, SNP-array results, and pregnancy outcomes in fetuses with 7q11.23 deletions and duplications during the second and third trimesters, gathering comprehensive data from a Chinese medical center over several years.
- Seven fetuses with 7q11.23 deletions and six with duplications were diagnosed, revealing significant clinical abnormalities such as intrauterine growth restriction and various cardiovascular issues; the deletions were associated with more serious ultrasound findings.
- Most pregnancies (seven deletions and three duplications) were terminated due to the severe abnormalities discovered, indicating a high risk linked to these genetic conditions.
