ATS Medical of Minneapolis, Minnesota has announced winning the CE Mark from the European Union to market its ATS 3f replacement aortic valve. In an attempt at aortic bioprosthesis humor, the company calls it the “original you tube” claiming it functions more like a natural valve compared to competing products.
Features from the product page:
By using a single suture line at the annulus and tacking the commissural tabs to the sinotubular junction (STJ), the continuity between the annulus and the STJ is restored with implantation of the ATS 3f Aortic Bioprosthesis. Maintaining the continuity between the annulus and the STJ, without a second suture line at the sinuses, preserves sinus form and function. Sinuses facilitate better vortex formation early in systole and smooth closure of the aortic vale, thereby avoiding the buildup of abnormal stress in the leaflet.
Turbulent flow and greater leaflet stress is a consequence of sinus loss. Loss of sinuses results in leaflet and aortic wall contact, greater regurgitation during a longer systole and abnormal leaflet bending during closure. Because it is tubular, the ATS 3f Aortic Bioprosthesis restores physiologic, non-turbulent trans-prosthetic flow that is indistinguishable from flow across a native aortic valve. The ATS 3f Aortic Bioprosthesis is a stentless pericardial valve that replaces the diseased native aortic leaflets. Since there is no bulky stent, minimal tissue is implanted achieving essentially a 1:1 annulus to orifice ratio and laminar flow, just like a native valve. Because it is tubular, the ATS 3f Aortic Bioprosthesis restores native valve stress distribution to the entire aortic root. The form and function of a native valve is reproduced with the implantation of the ATS 3f Aortic Bioprosthesis resulting in minimal stress at the commissures, just like a native valve.
