Once symptoms are present, outcomes are extremely poor unless an intervention to relieve obstruction occurs. Accordingly, the 2014 American Heart Association (AHA)/American College of Cardiology (ACC) guideline for the management of patients with valvular heart disease made the following recommendations [8] :

  • Aortic valve replacement (AVR) is recommended in patients with symptomatic severe AS (stage D) promptly after the onset of symptoms unless significant comorbid conditions exist that would prevent intervention (class I recommendation; level of evidence, B)
  • AVR is also recommended for asymptomatic patients with severe AS and an LVEF of less than 50% (stage C2); in these patients, survival is better for those who undergo AVR than for those treated medically (class I recommendation; level of evidence, B)
