REDUCE LAP-HF TRIAL II
A Study to Evaluate the Corvia Medical, Inc. IASD® System II to Reduce Elevated Left Atrial Pressure in Patients With Heart Failure
Multicenter, Prospective, Randomized Controlled, Blinded Trial, with a Non-implant Control group; 1:1 randomization.

Following supine bicycle exercise testing to assess eligibility, the eligible patients are randomized to the treatment or control group.

All patients will be sedated, and both treatment and control arm patients will undergo placement of a femoral venous access sheath after randomization.

Patients randomized to the treatment arm will undergo a fluoroscopically and intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE) guided trans-septal puncture and IASD System II implant procedure. Patients randomized to the control arm will undergo ICE from the femoral vein or TEE for examination of the atrial septum and left atrium.

Patients will be evaluated at pre-specified time intervals and followed for 5 years.

All patients will be unblinded after the 24 month follow up visit. Patients randomized to the control arm will be allowed to cross-over to the treatment arm at ≥ 24 months post-control procedure provided patient selection criteria are met at that time. Cross-over patients will then be followed for 5 years after cross-over.

Interventional
Not Applicable
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Treatment
Heart Failure
  • Device: IASD System II implant
    The primary component of the system is an implant placed in the atrial septum designed to allow left to right flow between the left atrium and right atrium to reduce the elevated left atrial pressure.
  • Other: intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE)
    intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE) for examination of the atrial septum and left atrium.
  • Experimental: Treatment
    Patients randomized to the treatment arm will undergo a fluoroscopically and intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE) guided trans-septal puncture and IASD System II implant procedure.
    Intervention: Device: IASD System II implant
  • Sham Comparator: Control
    Patients randomized to the control arm will undergo ICE from the femoral vein or TEE for examination of the atrial septum and left atrium.
    Intervention: Other: intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE)
