Aortic valve stenosis, a common condition in adults, often requires valve replacement due to age and risk factors. Surgical intervention is recommended for symptomatic severe cases or impaired heart function.

Area of Science:

  • Cardiology
  • Valvular Heart Disease

Background:

  • Aortic valve stenosis (AVS) is the leading indication for prosthetic valve replacement in adults.
  • Its prevalence escalates with age, and the degenerative-calcific form is linked to atherosclerotic risk factors.
  • AVS causes pressure overload, leading to left ventricular hypertrophy and potential heart failure.

Purpose of the Study:

  • To summarize the pathophysiology, clinical presentation, diagnosis, and management of aortic valve stenosis.
  • To highlight the diagnostic role of echocardiography in assessing stenosis severity.
  • To delineate treatment strategies based on symptom status and left ventricular function.

Main Methods:

  • Review of clinical presentation, including dyspnea, angina, and syncope.
  • Physical examination findings such as systolic murmurs.

  • Diagnostic evaluation using electrocardiography (ECG) and echocardiography to measure gradients and orifice area.

    • Main Results:

    • Echocardiography is crucial for quantifying AVS severity by measuring pressure gradients and valve area.
    • Severe AVS manifests with symptoms like dyspnea and angina, or impaired left ventricular function.
    • ECG typically reveals left ventricular hypertrophy.

    Conclusions:

    • Surgical valve replacement is indicated for symptomatic severe aortic valve stenosis or when left ventricular function is compromised.
    • Asymptomatic patients with preserved left ventricular function require conservative management and monitoring.
    • Early diagnosis and appropriate management are key to improving outcomes in aortic valve stenosis.
