The device is introduced through the femoral vein using a transseptal approach – through the right atrium and then through the fossa ovalis to the left atrium.
- Implant deployment
The Implant Delivery System can be steered to reach any point on the annulus. Approximately a dozen anchors are sequentially deployed as the tip is navigated along the posterior annulus, exactly as a standard annuloplasty band would be sutured during an open-heart procedure.
- Implant adjustment and MR reduction
After completion of implant deployment, the Size Adjustment Tool (SAT) is introduced over a wire. By turning a knob, the implant can be adjusted bi-directionally to reshape the annulus. This is performed under real-time beating-heart echo to eliminate MR.
A distinctive aspect of the procedure is that it is performed solely in the left atrium with no contact with the left ventricle, thereby enhancing the procedure’s safety profile.
