DurAVR™ THV Demonstrates Exceptional Results in Second Valve-in-Valve Case
Dr. Janar Sathananthan with his team from St. Paul’s Hospital,
A ViV procedure is required for patients with a life-threatening situation wherein their current bioprosthetic aortic valve is failing due to calcification or structural deterioration, and a new heart valve must be implanted inside the failing valve. These patients are at high risk for another surgery and require a minimally invasive treatment option. Currently available commercial products can leave patients with a high risk of remaining in a diseased state post-procedure, with unsatisfactory high gradients. Canada’s SAP exists so that life-saving technology not currently available for commercial use in
Dr Janar Sathananthan, an interventional cardiologist at Vancouver General and St Paul’s Hospital and a world expert on bench testing the hemodynamic effects of different valves used in ViV procedures, made the request to Health Canada to make DurAVR™ THV available for this procedure.
DurAVR™ THV was implanted in a 79-year-old female who was previously implanted with a Trifecta surgical valve that had severely degenerated, causing debilitating symptoms. The intraoperative results after DurAVR™ THV was implanted were phenomenal, with a mean pressure gradient of 7mmHg, restoring near-normal physiology. The patient was safely discharged less than 24 hours after the procedure.
Dr. Sathananthan commented:
“DurAVR™ THV performed exceptionally well during this complex ViV procedure. Today’s case demonstrated what we saw in preclinical testing, that DurAVR™ THV has the potential to offer superior gradients for ViV patients. This is a great result in a small surgical valve at high risk for elevated gradients.”
Dr. Chris Meduri, Anteris Technologies CMO, Commented:
“DurAVR™ THV has been purposely designed in close partnership with the world’s leading TAVR physicians as a solution to achieve near-normal blood flow. As we continue to progress and build the body of clinical evidence for the DurAVR™ THV system, we believe that the unique design of this valve is behind the exceptional best-in-class results and will be the ideal choice for patients with both native severe aortic stenosis and those needing a ViV procedure. As Dr. Sathananthan has stated, these results do not come as a surprise. Extensive preclinical work in partnership with a large number of leading physicians has demonstrated a superior hemodynamic result compared to commercially available products, both in native aortic stenosis and in valve-in-valve procedures. With a rapidly growing number of degenerating AVRs, this valve will have a dominant role in treating these patients.”

About Anteris Technologies (ASX: AVR)
Anteris Technologies Ltd (ASX: AVR) is a structural heart company committed to designing, developing, and commercialising innovative medical devices. Founded in
The Company’s lead product, DurAVR™, is a transcatheter heart valve (THV) for the treatment of aortic stenosis. DurAVR™ THV has been designed in partnership with the world’s leading interventional cardiologists and cardiac surgeons, and is the first transcatheter aortic valve replacement (TAVR) to use a single piece of bioengineered tissue. This biomimetic valve is uniquely shaped to mimic the performance of a healthy human aortic valve.
The ComASUR™ Delivery System is designed to provide controlled deployment and accurate placement of the DurAVR™ THV with balloon-expandable delivery, allowing precise alignment with the heart’s native commissures to achieve desired valve positioning.
Anteris Technologies is set to revolutionise the structural heart market by delivering clinically superior solutions that meet significant unmet clinical needs.
