The PARTNER trial

The PARTNER trial cohort B1

PARTNER Trial Flowchart

The PARTNER (Placement of AoRtic TraNscathetER Valves) Trial represents a paradigm shift in clinical investigation and interpretability. As the world’s first prospective, randomized, and controlled trial for transcatheter heart valves, the PARTNER Trial sets new standards in site selection, case screening, study management, multidisciplinary teamwork, and patient follow-up.1

The PARTNER Trial consists of two individually powered patient cohorts.

  • In Cohort A, the safety and effectiveness of the Edwards SAPIEN transcatheter heart valve (THV) was compared to surgical aortic valve replacement (sAVR) in high-risk patients with severe aortic stenosis. The results of Cohort A were published in 2011.2
  • In Cohort B, the safety and effectiveness of the Edwards SAPIEN THV was compared to best medical management (standard therapy) in inoperable patients with severe aortic stenosis. Patient selection required at least two cardiothoracic surgeons and an interventional cardiologist to agree that patients were not suitable candidates for surgery.1
