The EARLY TAVR trial

A Clinical Trial for Severe Aortic Stenosis Patients Who Have No Symptoms

Trial Objective

To establish the safety and effectiveness of the Edwards SAPIEN 3/ SAPIEN 3 Ultra transcatheter heart valve (THV) compared with clinical surveillance (CS) in asymptomatic patients with severe, calcific aortic stenosis

Trial Background

Recommended treatment for patients with asymptomatic stenosis (AS) includes following patients clinically until they become symptomatic, left ventricular dysfunction develops, or cardiac surgery is recommended for other reasons.

Practical challenges with clinical surveillance include:

  1. Interpreting symptoms is often difficult
  2. AS progression is variable and rapid deterioration may occur
  3. Late symptom reporting may result in irreversible myocardial damage with worsened prognosis after AVR

Whether early intervention before symptoms develop will improve outcomes remains unknown and has never been studied in a randomized trial.

Trial Design

Patients will undergo a treadmill stress test to determine if they are asymptomatic with severe aortic stenosis.

Asymptomatic

Negative stress test* OR confirmation via medical history

Primary Endpoint

2 year composite of all-cause death, all stroke, and unplanned cardiovascular hospitalization

Symptomatic

Positive stress test*

Registry

Commerical AVR (TAVR or SAVR)

*For patients who can perform treadmill stress test

Key Study Criteria

  • 65 years of age or older
  • Severe aortic stenosis defined as:
    1. Aortic valve area (AVA) ≤ 1.0 cm2 or AVA index ≤ 0.6 cm2/m2
      and
    2. Peak jet velocity ≥ 4.0 m/s or mean gradient ≥ 40 mmHg
  • Patient is asymptomatic defined as:
    1. Negative treadmill stress test
      or
    2. Physician assessment of patient history if unable to perform a stress test
  • LV ejection fraction ≥ 50%
  • Society of Thoracic Surgeons (STS) risk score ≤ 10
