Valve Calcification in Aortic Stenosis: Etiology and Diagnostic Imaging Techniques

Area of Science:

• Cardiology
• Pathophysiology
• Medical Imaging

Background:

• Aortic stenosis is the most prevalent valvulopathy in Western countries, with increasing incidence due to population aging.
• Severe aortic stenosis affects up to 8% of individuals over 84 years old, leading to significant morbidity and mortality.
• Previously viewed as a degenerative process, it is now recognized as a complex condition sharing mechanisms with atherosclerosis.

Purpose of the Study:

• To review the pathophysiological mechanisms of aortic stenosis onset and progression.
• To analyze the current utility of cardiac imaging techniques in diagnosing aortic stenosis.
• To provide a comprehensive overview for effective diagnosis and therapeutic planning.

Main Methods:

• Literature review of pathophysiological mechanisms.
• Analysis of current cardiac imaging modalities for aortic stenosis diagnosis.
• Synthesis of information on disease progression and diagnostic strategies.

Main Results:

• Aortic stenosis pathogenesis involves complex mechanisms akin to atherosclerosis.
• Cardiac imaging plays a crucial role in accurate diagnosis and severity stratification.
• Understanding these factors is vital for optimal therapeutic decision-making.

Conclusions:

• Aortic stenosis is a complex, multifactorial disease requiring accurate diagnosis.
• Cardiac imaging is essential for assessing severity and guiding treatment strategies.
• Further research into pathophysiological mechanisms can improve patient outcomes.
