Cardiovascular disease in Williams syndrome

Area of Science:

• Cardiology
• Genetics
• Pediatrics

Background:

• Williams syndrome is a genetic disorder affecting multiple body systems.
• Cardiovascular abnormalities are a primary cause of illness and death in Williams syndrome patients.
• Elastin deficiency underlies the cardiovascular complications observed in Williams syndrome.

Purpose of the Study:

• To review recent advancements in managing cardiovascular issues in Williams syndrome.
• To highlight current understanding of the etiology of cardiovascular problems in Williams syndrome.
• To discuss the effectiveness of various treatment modalities for cardiovascular manifestations.

Main Methods:

• Review of recent literature on cardiovascular manifestations in Williams syndrome.
• Analysis of current therapeutic strategies, including pharmacological, surgical, and transcatheter interventions.
• Evaluation of outcomes for different cardiovascular conditions, such as supravalvar aortic stenosis and peripheral pulmonary artery stenosis.

Main Results:

• Cardiovascular abnormalities affect 80% of Williams syndrome patients, predominantly arterial stenoses.
• Stenoses in Williams syndrome appear linked to deficient circumferential arterial growth.
• Surgical interventions for supravalvar aortic stenosis and multilevel pulmonary artery reconstruction show good to excellent results.
• Pharmacological therapies show promise in animal models but are less established in humans.
• Transcatheter interventions are generally ineffective for Williams syndrome-related cardiovascular issues.

Conclusions:

• Cardiovascular abnormalities significantly impact the clinical course of Williams syndrome.
• Advances in surgical techniques, medical therapies, and periprocedural management are crucial for improving cardiovascular outcomes.
• Personalized risk stratification and management algorithms can mitigate cardiovascular complications.
