Brief Summary:
Multicenter, Prospective, Randomized, Sham Controlled, Double Blinded Clinical Trial, with; 1:1 randomization

Condition or disease Intervention/treatment Phase
Heart Failure Heart Failure, Diastolic Device: Corvia Atrial Shunt System / IASD System II Other: Intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE) Not Applicable

Detailed Description:

Following supine bicycle exercise hemodynamic assessment to verify eligibility, patients are sedated then randomized to the treatment or control group. Patients in both arms will undergo placement of femoral venous access sheath.

Patients randomized to the treatment arm will undergo a fluoroscopically and intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE) guided trans-septal puncture and Corvia Atrial Shunt 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.

Arm Intervention/treatment
Experimental: Treatment
Participants randomized to the treatment arm will undergo a fluoroscopic and intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE) guided trans-septal puncture and InterAtrial Shunt Device (IASD) System II implant procedure.

Sham Comparator: Control
Participants randomized to the control arm will undergo fluoroscopy and intracardiac echocardiography from the femoral vein or transesophageal echocardiography, for examination of the atrial septum and left atrial appendage.
 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.
