The purpose of the EXPAND TAVR II Pivotal Trial is to explore the treatment of moderate aortic stenosis (AS) with early transcatheter aortic valve replacement (TAVR) before AS becomes severe. Early treatment of AS may help preserve cardiac function, prevent, or slow further deterioration in cardiac function, and prevent death in some patients.
CAUTION: Investigational use. Device is being investigated for the treatment of moderate aortic stenosis. Not approved for this use by the FDA.
~650 randomized subjects
~100 centers
Australia, Canada, Europe, Israel, Japan, New Zealand, and United States
10 years of follow-up
Multicenter, international, prospective, randomized

Use identifier number NCT05149755 to see details on the EXPAND TAVR II Pivotal Trial.
Patients presenting with LVEF < 50%, SVI ≤ 35 ml/m2, AVA of ≤ 1.0 cm2, and Max aortic velocity ≥ 3.0 m/sec and < 4.0 m/sec, or mean gradient ≥ 20 mmHg and < 40 mmHg at rest may undergo low-dose DSE to assess if subject has moderate AS versus low-flow, low-gradient severe AS.
In absence of non-cardiopulmonary factors (e.g., orthopedic or neurologic problems).
For patients with concordant AS severity parameters only.
