Body Mass Index (BMI) > 45; BMI 40 - 45 is also excluded unless in the opinion of the investigator, vascular access can be obtained safely 28. Severe depression and/or anxiety 29. Currently participating in an investigational drug or device study that would interfere with the conduct or results of this study. Note: trials requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational 30. In the opinion of the investigator, the Participant is not an appropriate candidate for the study.

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.
