Brief Summary:
A study to evaluate the Corvia Medical, Inc. IASD® System II to REDUCE Elevated Left Atrial Pressure in Patients with Heart Failure.

Condition or disease Intervention/treatment Phase
Heart Failure Device: Inter-Atrial Shunt Device Other: Intracardiac Echo Not Applicable

Detailed Description:
The primary objective of this randomized controlled clinical study is to evaluate the peri-procedural safety and potential effectiveness (mechanistic effect) of implanting the IASD System II in heart failure patients with an LV ejection fraction >40%, elevated left sided filling pressures, and who remain symptomatic despite optimal Guideline Directed Medical Therapy (GDMT). Clinical outcomes will also be evaluated.

Arm Intervention/treatment
Experimental: Treatment with Inter-Atrial Shunt Device
Once all study criteria have been met, if randomized to this arm, patients will receive the IASD implant.
Device: Inter-Atrial Shunt Device
An implantable device placed in the interatrial septum
Other Name: IASD

Placebo Comparator: Control
Once all study criteria have been met, if randomized to this arm, patients will not receive the implant. They will undergo an intracardiac echo only, with the option to crossover at 1 year.
Other: Intracardiac Echo
Patients randomized to the control arm will undergo intra cardiac echocardiography, with examination of the atrial septum and left atrial appendage.

Primary Outcome Measures :
  1. The change in supine exercise PCWP from baseline [ Time Frame: 1 Month Post Procedure ]
  2. The composite incidence of one or more of the following: major adverse cardiac, cerebrovascular embolic, or renal events (MACCRE) [ Time Frame: 1 Month Post Procedure ]
