Focus on a rare clinical entity: unicuspid aortic valve disease

Area of Science:

• Cardiology
• Congenital Heart Disease
• Aortic Valve Disease

Background:

• The natural history and clinical implications of unicuspid aortic valve (UAV) are poorly understood, unlike bicuspid aortic valves.
• A universally accepted diagnostic work-up and treatment recommendations for UAV are yet to be established.

Purpose of the Study:

• To provide an overview of recent literature on the pathophysiology, diagnostic tools, and surgical therapy options for UAV.
• To highlight surgical treatment options, including pros and cons, particularly for young adult populations with UAV.

Main Methods:

• Literature review of recent studies on unicuspid aortic valve.
• Analysis of diagnostic tools and surgical interventions.
• Focus on early-onset symptomatic aortic valve disease in UAV patients.

Main Results:

• Pathophysiology of UAV is not well understood due to its rare prevalence.
• Symptomatic aortic valve disease in UAV patients often presents at an earlier life stage.
• Various surgical treatment options exist, with specific considerations for young adults.

Conclusions:

• Large-scale prospective observational studies with standardized diagnostic criteria are essential to elucidate the clinical course of UAV.
• Development of appropriate and evidence-based treatment strategies for UAV patients is urgently required.
