Anteris pushing boundaries…

The above image is a screenshot from an Xray Fluroscopy video of a world first Valve-in-Valve replacement of both the Aortic valve and the Mitral valve of a patient using Anteris’ DurAVR. Hopefully there is an official Anteris press release this week about this.

This is exceptional as DurAVR — as the name suggests — is designed only for Aortic Valve Replacement, but clearly has some versatility. Without the text I’ve pasted below I’d have no idea what I was looking at, but you can see the mesh frame in the top right is already expanded — that is the Aortic DurAVR from the month before. The one on the left is the Mitral DurAVR implantation during the balloon expansion. There appears to be no previous mesh frames/stents as the earlier valve replacements in this patient were surgical (as opposed to Transcatheter as in TAVR). In both cases the DurAVR is placed inside the surgically replaced valves, which themselves are inside the patient’s failed native valves. Dr Meduri is Anteris’ Chief Medical Officer.

First-in-Human Dual Valve-in-Valve Success with DurAVR™ THV
We are proud to share a groundbreaking case highlighting the versatility and performance of the DurAVR™ Transcatheter Heart Valve (THV) Anteris Technologies in both aortic and mitral valve-in-valve (ViV) procedures.
Patient Profile:
• A patient presented with a failed 25mm Sorin Crown aortic valve (True ID 21mm) exhibiting a mean gradient (MG) of 55 mmHg.
• Additionally, the patient had a degenerated 31mm SJM Biocor Epic mitral valve (True ID 27mm) with severe mitral stenosis (MG 18 mmHg) and moderate to severe mitral regurgitation.
Aortic ViV Procedure:
• The aortic valve was addressed first with a straightforward transfemoral approach
• Utilizing DurAVR™’s precise commissural alignment capabilities, the valve was successfully deployed with perfect alignment to the surgical valve.
• This resulted in a remarkable reduction of the MG to 5 mmHg at the 30-day echocardiographic follow-up.
Mitral ViV Procedure:
• One month later, a transseptal approach was employed for the mitral ViV.
• The deployment was straightforward, and post-procedure assessments revealed:
- Mean gradient of only 2 mmHg
- No residual mitral regurgitation
- Beautiful flow through the valve as seen on the TEE images in the surgeon's view, demonstrating the full opening of the biomimetic leaflet design.
Key Highlights of DurAVR™ THV:
• Exceptional Hemodynamics: Achieves low transvalvular gradients in both aortic and mitral positions.
• Versatile Deployment: Demonstrates effective performance in both transfemoral and transseptal approaches.
• Innovative Design: Features a single-piece, biomimetic ADAPT® tissue design that facilitates optimal leaflet coaptation and flow dynamics.
This case exemplifies the promising capabilities of DurAVR™ THV in addressing complex structural heart interventions. Much more coming in the upcoming PARADIGM Global trial! Incredible collaboaration across physicians and the Anteris team to successfully treat this patient! Vinayak Bapat Rishi Puri, M.D., Ph.D., F.R.A.C.P.
