What is TAVR?
Transcatheter aortic valve replacement (TAVR) system is a catheter-based device that delivers the valve to the heart through a blood vessel (femoral artery) in the leg. When compared to surgical aortic valve replacement (SAVR), the less-invasive TAVR technology has the same potential to improve cardiac function while improving procedural outcomes and quality of life.
With TAVR, replacing a diseased aortic heart valve without open heart surgery can be a reality.
The HLT TAVR procedure
The Meridian® Valve is designed to restore normal blood flow across the diseased aortic valve and reduce symptoms of the disease. Since patient anatomies and the aortic stenosis disease process vary, the system is uniquely designed allowing physicians to reposition or fully retrieve the valve to optimize the implant position. These video animations illustrate the procedure.
Physicians can assess valve performance prior to final valve release, and the option to retrieve or reposition if necessary.
This animation illustrates how to implant the Meridian® Valve.
The procedure includes crossing the diseased aortic valve, positioning in the annulus, deploying the self-expanding nitinol support structure, inverting the valve and exposing the valve leaflets.
This animation illustrates how the Meridian® Valve is repositioned by withdrawing it into catheter, repositioning it at the annular level and continuing with procedure.
This animation illustrates how the Meridian® Valve is retrieved, showing how the valve is withdrawn into catheter and removed.
