Official Title
A Study to Evaluate the Corvia Medical, Inc. IASDĀ® System II to Reduce Elevated Left Atrial Pressure in Patients With Heart Failure
Region Sponsors
California - Northern
Corvia Medical
Acronym KP IRB No.
REDUCE CN-17-2931
Study Type Phase
Clinical Trial n/a
Study Population Description
(Adult, Older Adult) Male and Female who have documented chronic symptomatic heart failure (HF)
Multicenter, Prospective, Randomized Controlled, Blinded Trial, with a Non-implant Control group; 1:1 randomization.
Detailed Description
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.
Gender Age Limit
Male & Female 40 years & older
Inclusion Criteria
  • Chronic symptomatic Heart Failure (HF) documented by one or more of the following: * (1) Symptoms of HF requiring current treatment with diuretics for > 30 days, * (2) NYHA class II with a history of > NYHA class II, NYHA class III or ambulatory NYHA class IV symptoms at screening, or signs within past 12 months, (AND) * 1 hospital admission with HF as primary or secondary diagnosis, or treatment with intravenous or intensification of oral diuresis for HF in a healthcare facility (emergency department/acute care facility), within the 12 months prior to study entry, (OR) an NT-pro BNP value > 150 pg./ml in normal sinus rhythm, > 450 pg./ml in atrial fibrillation, or a BNP value > 50 pg./ml in normal sinus rhythm, > 150 pg./ml in atrial fibrillation within the past 6 months
