[Prevalence and pathogenesis of aortic valve calcifications]

Area of Science:

• Cardiology
• Radiology
• Biochemistry

Background:

• Calcific aortic valve disease impacts over 25% of individuals aged 65+, elevating cardiovascular event risk by 50%.
• The clinical implications of aortic valve calcification, particularly when incidentally found on chest CT scans, remain largely uncharacterized.
• The pathogenesis of calcific aortic valve disease is multifactorial, with calcification regulators playing a crucial role.

Purpose of the Study:

• To provide a comprehensive overview of the prevalence and clinical significance of incidentally detected aortic valve calcifications.
• To explore the involvement of calcification inhibitors in the development of aortic valve calcification.

Main Methods:

• Review of incidental findings of aortic valve calcification on radiologic examinations, primarily chest CT scans.
• Analysis of existing literature on the prevalence and associated cardiovascular risks.
• Discussion of the role of specific calcification inhibitors in the disease process.

Main Results:

• Incidental detection of aortic valve calcification on imaging studies is common in older populations.
• Aortic valve calcification is linked to increased cardiovascular event rates.
• Calcification inhibitors are implicated as key players in the pathogenesis of aortic valve calcification.

Conclusions:

• Incidental aortic valve calcification detected on imaging is clinically significant and associated with adverse cardiovascular outcomes.
• Understanding the role of calcification inhibitors may offer new therapeutic targets for calcific aortic valve disease.
