Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Corvia Atrial Shunt System / IASD System II
Other interventions - Intra-cardiac echocardiography (ICE), or transesophageal echocardiography (TEE)

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.


Treatment: Devices: Corvia Atrial Shunt System / IASD System II
The primary component of the system is an implant placed in the atrial septum designed to allow left to right flow between the left atrium and right atrium to reduce the elevated left atrial pressure.

Other interventions: 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.
