When should intervention be considered for a patient with aortic stenosis?

Intervention should be performed for patients with:
- - Symptomatic severe aortic stenosis
  - Asymptomatic severe aortic stenosis with any of:
    - Systolic LV dysfunction (LVEF <50%) not due to another cause
    - Abnormal exercise testing
    - Markedly elevated BNP
    - Severe pulmonary hypertension without other explanation
  - Intervention should not be performed in patients:
    - With severe comorbidities (e.g. associated with survival <1 year)
    - When the intervention is unlikely to improve quality of life or survival
