Aortic Aneurysm: Etiopathogenesis and Clinicopathologic Correlations.

Area of Science:

• Cardiovascular Medicine
• Genetics
• Pathology

Background:

• Aortic aneurysm (AA) is a life-threatening aortic disease with potential for rupture.
• AA diagnosis is variable among patients with dilated aorta identified via imaging.
• The etiopathogenesis of many aortic diseases, including AA, remains largely unclear.

Purpose of the Study:

• To highlight the diagnostic challenges and unclear etiopathogenesis of aortic aneurysms.
• To emphasize the importance of considering genetic factors and clinicopathological characteristics in AA.
• To underscore the need for individualized patient management in aortic diseases.

Main Methods:

• Review of current understanding of aortic aneurysm diagnosis and pathogenesis.
• Discussion of genetic mutations associated with aortic diseases (e.g., ACTA2, MYH11, SMAD3).
• Emphasis on clinicopathological correlation for patient stratification.

Main Results:

• Aortic aneurysm diagnosis relies on imaging but etiopathogenesis is often unclear.
• Genetic mutations in proteins like ACTA2, MYH11, and SMAD3 are identified in some cases.
• Phenotypic variability in patients with identified genetic mutations poses challenges.

Conclusions:

• Individualized consideration of clinicopathological characteristics is essential for managing aortic aneurysm patients.
• Further research is needed to elucidate the complex etiopathogenesis of aortic aneurysms.
• Personalized medicine approaches are critical for improving outcomes in aortic diseases.
