On what does treatment depend?
AS is a progressive condition that is definitively treated with aortic valve replacement or repair, the urgency of which depends on disease severity.
Describe the overall approach.
Symptomatic and/or severe AS: Aortic valve replacement or repair is usually indicated.
Asymptomatic or mild-to-moderate AS: usually treated conservatively; consider early aortic valve replacement in select patients.
All patients
Provide supportive care: e.g., manage comorbidities (e.g., hypertension, diabetes), monitor progression with serial echocardiograpy, provide IE prophylaxis for at-risk patients.
Manage critical complications of AS (e.g., acute heart failure) with individualized critical care focusing on acute stabilization and expedited surgical trreatment.
List indications for aortic valve replacement and repair.
Symptomatic patients with severe, high-gradient AS
Asymptomatic patients with severe AS and:
Significantly ↓ LVEF
Undergoing cardiac surgery for other indications
Describe the procedure of aortiv valve replacement/repair.
Surgical AVR (SAVR) is recommended for patients with:
Age < 65 years
Life expectancy > 20 years
Low to moderate surgical risk
Transcatheter AVR (TAVR)
Recommended for patients with:
Age > 80 years
Life expectancy < 10 years
High or prohibitive surgical risk and predicted survival of > 12 months [9]
Percutaneous balloon valvuloplasty [9]
May be used in children, adolescents, and young adults
Limited role in older patients
What are complications?
The following can rapidly lead to decompensation and circulatory collapse in patients with severe AS:
Cardiogenic shock
Acute heart failure (AHF)
Atrial fibrillation with RVR
Prognosis?
Asymptomatic patients: Mortality rate is < 1% in a given year. [24]
Symptomatic patients: Mortality rate in the first 2 years is > 50% if left untreated.
