Register a trial

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.
