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. Peri-procedural, and 1 month Major Adverse Cardiac, Cerebrovascular, and Renal Events (MACCRE) [ Time Frame: 1 Month Post Implant ]

    The primary safety outcome measure is the incidence of one or more of the following major adverse cardiac, cerebrovascular embolic, or renal events (MACCRE) defined as:

    1. Cardiovascular death through 1-month post implant;
    2. Embolic stroke through 1-months post implant;
    3. Device and or procedure related adverse cardiac events through 1-month post implant;
    4. New onset or worsening of kidney dysfunction (defined as eGFR decrease of > 20 ml/min) through 1-month post implant

  2. Change in supine exercise pulmonary capillary wedge pressure (PCWP) [ Time Frame: 1 Month Post Implant ]
    Change in supine exercise pulmonary capillary wedge pressure (PCWP), as assessed by an independent blinded hemodynamic core laboratory, across the four values measured at each visit (values at 20W, 40W, 60W and 80W).

Secondary Outcome Measures :
  1. Change in exercise PEAK pulmonary capillary wedge pressure (PCWP) from baseline [ Time Frame: 1 Month ]
  2. Cardiovascular death [ Time Frame: 12 Months ]
  3. Rate of total (first plus recurrent) HF admissions/emergency clinic visits or acute care facilities for IV diuresis for HF [ Time Frame: 12 Months ]
  4. Change in Quality Of Life Questionnaire (EQ-5D) [ Time Frame: 12 Months ]
  5. Change in Kansas City Cardiomyopathy Questionnaire (KCCQ score) [ Time Frame: 12 Months ]
