Aortic Valve Replacement (AVR) is reasonable:
Recommendations
|
COR
|
LOE
|
AVR is reasonable for asymptomatic patients with very severe AS (aortic velocity ≥ 5 m/s) (stage C2) and low surgical risk
|
IIa
|
B
|
AVR is reasonable in asymptomatic patients (stage C1) with severe AS and an abnormal exercise test
|
IIa
|
B
|
AVR is reasonable in symptomatic patients with low-flow/low-gradient severe AS with reduced LVEF (stage S1) with a low-dose dobutamine stress study that shows an aortic velocity ≥ 4 m/s (or mean gradient ≥ 40 mm Hg) with a valve area ≤ 1.0 cm 2 at any dobutamine dose
|
IIa
|
B
|
AVR is reasonable for patients with moderate AS (stage B) (velocity 3.0–3.9 m/s) who are undergoing other cardiac surgery

AVR may be considered:
Recommendations
|
COR
|
LOE
|
AVR may be considered for asymptomatic patients with severe AS (stage C1) and rapid disease progression and low surgical risk
|
IIb
|
C
|
AVR may be considered in symptomatic patients who have low-flow/low-gradient severe AS (stage S2) who are normotensive and have an LVEF ≥ 50% if clinical, hemodynamic, and anatomic data support valve obstruction as the most likely cause of symptoms
