Asymptomatic Severe Aortic Stenosis: Contemporary Evaluation and Management

Area of Science:

• Cardiology
• Cardiac Surgery
• Valvular Heart Disease

Background:

• Aortic stenosis (AS) is the most common valvular heart disease, particularly in the elderly.
• Current guidelines recommend intervention for symptomatic severe AS, but evidence for intervention in asymptomatic patients is limited.
• The optimal timing for aortic valve replacement (AVR) in asymptomatic severe AS (ASAS) remains controversial.

Purpose of the Study:

• To review contemporary evaluation and management strategies for ASAS.
• To summarize scientific evidence on the optimal timing for intervention in ASAS.
• To discuss indications for early AVR in ASAS before irreversible myocardial damage occurs.

Main Methods:

• Literature review of contemporary studies and guidelines.
• Analysis of evidence supporting intervention timing in ASAS.
• Evaluation of advancements in percutaneous and surgical AVR approaches.

Main Results:

• Evidence supporting current indications for AVR in asymptomatic patients is considered weak.
• Advancements in AVR techniques have reduced mortality and complications.
• Some evidence suggests earlier AVR may prevent subclinical myocardial damage.

Conclusions:

• The optimal timing for intervention in ASAS requires further investigation.
• Early AVR may be beneficial in specific ASAS scenarios to prevent irreversible myocardial damage.
• Improved AVR techniques support considering earlier intervention in select ASAS patients.
