Magnetic Resonance Imaging (MRI) Safety Information

This device is labeled as MR Conditional. This means that the device has a demonstrated safety in a specified MRI environment with the defined conditions of use listed. The information on this page provides only a summary of MR conditions and is intended as a reference for the U.S. only. For a full version of conditions, please see product Instructions for Use (IFU). 

The information on this page is current as of November 2022. For the most current and complete MR safety information on any product, always refer to the IFU at


MR status MR Conditional
Static magnetic field strengths 1.5 tesla or 3.0 tesla only
Maximum spatial gradient 4000 gauss/cm (40 T/m) or less
Max whole-body-averaged specific absorption rate (SAR) <2 W/kg (normal operating mode)
Scan duration 15 minutes of continuous scanning
Image artifact (3 tesla, gradient echo pulse sequence) In non-clinical testing, the image artifact caused by the device extends approximately 5 mm from the GORE® CARDIOFORM ASD Occluder.
Time (post-implant) to safely scan Immediately after placement if conditions are met

INDICATIONS/INTENDED USE: The GORE® CARDIOFORM ASD Occluder is a permanently implanted device indicated for the percutaneous, transcatheter closure of ostium secundum atrial septal defects (ASDs). CONTRAINDICATIONS: The GORE® CARDIOFORM ASD Occluder is contraindicated for use in patients: unable to take anti-platelet or anticoagulant medications such as aspirin, heparin, or warfarin; with anatomy where the GORE® CARDIOFORM ASD Occluder size or position would interfere with other intracardiac or intravascular structures, such as cardiac valves or pulmonary veins; with active endocarditis, or other infections producing bacteremia, or patients with known sepsis within one month of planned implantation, or any other infection that cannot be treated successfully prior to device placement; with known intracardiac thrombi.
