Important Safety Information
MRI INFORMATION, PATIENT INFORMATION GUIDE, INSTRUCTIONS FOR USE
The Corvia Atrial Shunt System (IASD®) is indicated for the improvement in quality of life and reduction of heart failure related symptoms and events in patients with heart failure with preserved (HFpEF) or mid-range ejection fraction (HFmrEF) with elevated left atrial pressures, who remain symptomatic despite standard Guideline Directed Medical Therapy.
MAGNETIC RESONANCE (MR) IMAGING INFORMATION
Non-clinical testing demonstrated that the Corvia Atrial Shunt is MR Conditional. A patient with this device can be scanned safely in an MR system immediately after placement under the following conditions:
- Static magnetic field of 1.5-Tesla and 3-Tesla, only
- Maximum spatial gradient magnetic field of 4,000-Gauss/cm (40-T/m) or less
- Maximum MR system reported, whole body averaged specific absorption rate (SAR) of <2 W/kg (Normal Operating Mode)
Under the scan conditions defined, the Corvia Atrial Shunt is expected to produce a maximum temperature rise of 2.4°C after 15-minutes of continuous scanning (i.e., per pulse sequence).
In non-clinical testing, the image artifact caused by the Corvia Atrial Shunt extends approximately 5mm from this device when imaged using a gradient echo pulse sequence and a 3-Tesla MR system. The device shunt lumen cannot be visualized on T1-weighted, spin echo and gradient echo pulse sequences.
